Buying a home in Denver often means evaluating features many buyers haven’t thought about before, and chimneys are near the top of that list. One of the simplest but most important parts of a chimney system is the spark arrestor. It’s a small device with a big role in fire safety and overall fireplace performance.

What Is a Spark Arrestor?

A spark arrestor is a metal screen or mesh installed at the top of a chimney that prevents burning embers or sparks from escaping into the air. Think of it as a final safeguard between your fireplace and the surrounding environment. It allows smoke to exit freely while keeping small, hot particles inside the chimney where they belong.

What Does a Spark Arrestor Do?

A spark arrestor serves two main purposes: fire prevention and chimney protection.

First, it stops embers from escaping the flue and drifting into the surrounding area. That’s an especially important safeguard in Colorado’s dry climate. Even though modern homes are built with fire-resistant materials, floating sparks are unpredictable, and this small screen reduces that risk.

Second, it acts as a barrier against animals, debris, and wind-driven leaves. For instance, it creates a barrier to birds and small mammals looking for warm, sheltered spaces near the chimney. 

Does Your Denver Home Need a Spark Arrestor?

Most buyers will benefit from having one, especially in homes with wood-burning fireplaces. While local requirements vary, many older Denver homes were built before current fire-safety standards were put in place.

Even when not explicitly required, Colorado’s dry seasons, mixed urban-wildland edges, and higher winds make spark arrestors a practical safety feature. For buyers evaluating a chimney during a home inspection, it’s one of the easiest upgrades to look for because it provides reliable protection with minimal maintenance.

How to Tell if a Spark Arrestor Is Installed

If you’re touring homes, you can often see the spark arrestor from ground level by looking for a metal cap with a mesh screen around it. Most arrestors are built into the chimney cap itself.

During inspections, professionals confirm the presence of a spark arrestor by checking the top of the chimney, noting its condition, and verifying that the mesh openings are the correct size. This ensures that embers stay contained while allowing proper airflow.

What Are the Benefits of a Spark Arrestor?

1. Reduced Risk of Fire Spread

The main reason spark arrestors matter is simple: embers can travel. With Colorado’s weather swings and dry vegetation, an arrestor keeps sparks inside the flue where they pose no risk. This added protection becomes especially valuable in homes surrounded by mature landscaping or wood structures.

2. Improved Chimney Performance

A properly fitted spark arrestor helps stabilize airflow, which supports better drafting. When air moves through the chimney more efficiently, smoke exits smoothly, reducing smoke-back issues that can surprise first-time fireplace owners.

3. Critter and Debris Protection

Small animals often nest in chimney flues without any visible sign from the ground. A spark arrestor keeps the pathway clear by blocking entry, which prevents nesting material from creating airflow obstructions. Clear airflow leads to safer, more efficient burning, which ultimately supports the long-term health of the chimney system.

4. Weather and Wind Shielding

Denver’s winter storms and fast-moving winds can push snow, rain, and debris into an unprotected chimney. The spark arrestor acts as a shield while still letting smoke escape. This consistent design detail ensures the chimney continues functioning the way it was designed, even on rough weather days.

3 Common Spark Arrestor Problems 

Even though spark arrestors are fairly simple devices, they still experience wear and tear. When reviewing an inspection report, buyers might encounter a few of these common chimney-related issues:

Clogged or Dirty Mesh

Over time, soot accumulation or debris can clog the mesh. When that happens, airflow can be restricted, which may cause smoke to draft poorly. It’s a quick fix, but it’s helpful for buyers to understand why airflow matters.

Rust or Corrosion

Denver’s freeze-thaw cycles are hard on exterior metal. Spark arrestors built with lower-grade metals can rust faster, which weakens the structure. A rusted arrestor should be replaced to ensure it continues doing its job effectively.

Damaged or Missing Screens

Wind, storms, or age can cause tears or gaps in the mesh. Even a small opening can allow animals or embers through, so any damage should be repaired promptly.

Loose or Improper Fit

An arrestor that isn’t securely fastened can shift or detach. This is especially important for homes in areas exposed to stronger wind. Inspectors typically check the stability of the cap and the arrestor during routine evaluations.

How Are Spark Arrestors Maintained?

Annual Chimney Inspections

A yearly inspection is the best way to ensure the spark arrestor stays in good shape. Inspectors check for damage, corrosion, blockages, and proper airflow. Even if the fireplace is used lightly, these checks help catch early issues.

Occasional Cleaning

Depending on use, the mesh may need to be cleaned to remove soot or creosote buildup. This keeps smoke moving freely and helps reduce smoke-related issues inside the home. Cleaning intervals vary, but many homeowners schedule cleaning as part of broader chimney maintenance.

Replacing Older Components

If the arrestor is older, bent, or rusted, replacing it is often straightforward and inexpensive. Newer models offer better durability and tighter mesh standards, which means improved long-term safety with minimal ongoing effort.

What You Need to Know

A spark arrestor prevents embers, animals, and debris from entering or escaping the chimney. Denver’s dry climate makes it especially useful for home buyers. Look for proper installation, clean mesh, and rust-free materials. Simple maintenance keeps the fireplace safe, efficient, and ready for long-term use.

It’s a situation every homeowner faces eventually: the day your old water heater calls it quits. Whether you’re standing in a puddle or planning ahead before that happens, understanding your water heater replacement options can save you time, money, and stress.

For Colorado homebuyers, choosing the right system can make a big difference in comfort and energy costs. Here’s a simple breakdown of what to know before replacing your water heater and how to find the right fit for your home.

The Two Main Choices: Tank vs. Tankless

When it’s time for water heater replacement, most people start with the classic question: Do I stick with a tank or upgrade to tankless?

Tank water heaters are the traditional choice — large, insulated cylinders that store and heat water all day long. They’re familiar, relatively affordable to install, and straightforward to replace if your existing setup already uses one. But they also have downsides: tanks continuously use energy to keep water hot, even when you’re not using it. Over time, that “standby loss” can add up on your utility bills.

Tankless water heaters, on the other hand, heat water only when you need it. Instead of storing hot water, they activate when you turn on a faucet or shower, running cold water over a heat exchanger. That “on-demand” system is why they’re sometimes called instant water heaters.

Because they only heat water as needed, tankless systems tend to be more energy efficient. That’s a major plus for Colorado homeowners looking to lower monthly costs. They’re also compact, mounting neatly on a wall instead of taking up floor space.

However, tankless units come with higher upfront costs, and installation can be more complex. Homes converting from a tank system may need new venting or larger gas lines. And while they’re great for smaller households, larger families might notice a drop in water temperature if multiple showers, laundry, and the dishwasher run at once.

Exploring High-Efficiency Water Heaters

If you’re set on keeping a tank but want better performance, high-efficiency water heaters are worth a look. These models use advanced combustion and heat recovery technology to make the most of the energy they consume.

A standard gas water heater might operate at around 80% efficiency, while a high-efficiency model can reach 90% or more. That means less heat escapes through the vent and more goes into your water, translating to faster heating and lower energy waste.

The trade-off? Cost and complexity. HE units are more expensive to install and often require professional setup to ensure proper venting. But for long-term homeowners or energy-conscious buyers, the investment can pay off in reduced utility bills over time.

Considering Solar Water Heating Systems

For the environmentally minded, solar water heating systems are another replacement option. These setups use rooftop solar panels and a circulation system to preheat water before it enters your tank or tankless unit.

In sunny states like Colorado, this can offset a significant portion of your water heating costs. Many homeowners use solar as a supplement, letting the sun do most of the work while a conventional or tankless unit provides backup heating on cloudy days.

The main limitation is predictability: no sunlight means no solar gain. Installation also tends to cost more upfront, though some homeowners offset that with energy rebates or tax credits.

How Long Water Heaters Last

Another factor for buyers to keep in mind is lifespan. A standard tank water heater usually lasts 8–12 years, while tankless systems can run 15–20 years with proper maintenance. High-efficiency and solar systems vary based on usage and upkeep.

If you’re buying an older home, ask when the water heater was last replaced and look for signs of age such as rust and slow heating times. Replacing an outdated unit before it fails can prevent water damage and make your home more energy efficient.

Choosing the Right System for Your Home

There’s no single “best” water heater for every buyer. The right choice depends on your household size, water usage habits, and budget.

• Go with a tank if you want a lower upfront cost and straightforward installation.

• Consider tankless if you prioritize energy efficiency, space savings, and long-term value.

• Look into high-efficiency if you plan to stay in your home and want lower utility bills.

• Explore solar if sustainability and long-term savings are important to you.

Whatever route you take, the key is to understand your water heater replacement options early before an emergency forces a quick decision.

The Bottom Line on Water Heater Replacement

A water heater might not be the most exciting part of your new home, but it’s one of the most important for daily comfort. By learning the basics of tank, tankless, high-efficiency, and solar systems, homebuyers can make confident, informed choices that balance cost, efficiency, and convenience.

When you know your options, you can turn what feels like a stressful replacement into a smart investment and start your new home journey with hot water ready when you need it.

You’re walking through your new home, coffee in hand, when creeeak—the floorboard lets out that familiar protest. It’s a small sound, but it can make even the newest homeowner wonder: Is something wrong with my floor?

The good news? In most cases, squeaky floors are more of an annoyance than a serious issue. Still, those creaks can tell you something about how your home was built and how Colorado’s climate plays a part.

What Causes Squeaky Floors?

Squeaky floors can be caused by wood movement. Wood naturally expands and contracts as temperature and humidity levels change. In Colorado, where humidity levels can swing dramatically between seasons, these subtle shifts are common. When boards dry out in winter or swell slightly in summer, gaps can form between floorboards or between the flooring and subfloor. When you walk across those spots, the boards rub together and release that telltale sound.

Another common cause is loose fasteners. Over time, nails or screws holding your floorboards in place can loosen, especially in high-traffic areas like hallways or kitchens. When the board moves and the fastener doesn’t, you get friction and friction equals noise.

Finally, sometimes it’s simply construction settling. Even newer homes experience small movements in their framing and flooring systems as materials adjust to the local environment. It’s a normal process and not necessarily a sign of structural damage.

Are Certain Floors More Prone to Squeaks?

Yes. Solid hardwood floors tend to squeak more often than engineered wood or laminate, simply because they’re made entirely of wood. Homes built with wide-plank flooring may also creak a bit more than those with narrow planks, since wider boards expand and contract across a larger surface area.

That doesn’t mean something’s wrong with the installation or materials. It’s just the nature of wood reacting to its surroundings, especially in an environment with big temperature swings between day and night.

When Should You Be Concerned?

Most squeaks are harmless, but there are a few times when it’s worth taking a closer look. If you notice squeaking combined with visible gaps, sagging sections, or uneven flooring, it could indicate that the subfloor has separated from the joists beneath it. In rare cases, this can point to moisture issues, poor fastening, or structural settling that’s more than cosmetic.

For homebuyers, the key is to note where and when the squeaks occur. Consistent creaking across multiple rooms may be worth mentioning during an inspection, but an isolated squeak in an older home isn’t usually cause for alarm. A thorough home inspection can tell you whether it’s just wood movement or something that needs repair.

Simple Fixes You Can Try

If the squeak is driving you crazy, there are a few easy fixes you can try—no major renovation required.

• Lubricate the seams: Sprinkle a little powdered graphite or talcum powder between the floorboards, then step back and forth over the area to work it into the gaps. This helps reduce friction between boards.

• Tighten from below (if you have access): In unfinished basements or crawlspace, you can often pinpoint the squeak from below and add a short screw or wood shim to secure the subfloor to the joist.

• Use squeak-repair kits: Several hardware stores sell screw systems designed for squeaky floors. They let you tighten boards from above without damaging the surface.

These small tweaks often quiet the noise completely. But even if they don’t, remember: a squeaky floor isn’t a broken floor. It’s just wood doing what wood does.

A Little Character Never Hurts

In a way, squeaky floors tell a story. They creak where families gather, where kids race down hallways, where life happens. Especially in Colorado’s distinct climate, a bit of floor squeaking is almost inevitable.

So, while those creaks might make you pause, they rarely signal a real problem. Think of them as part of your home’s personality, an audible reminder that your house is made of living materials adapting to the world around it.

As electrical panels developed and evolved over the years, sometimes certain features turned out to be not so safe. If you do have an older panel, it’s important to be aware of era-specific defects that might be present.

There have been some pretty serious factory recalls throughout the decades – such as Federal Pacific Panels, Zinsco Panels, aluminum wiring etc. But in this blog, we will be discussing a much more recent electrical issue – the Square D AFCI recall.

What’s An AFCI?

Before we get into the Square D dilemma, let’s have a quick recap about Arc Fault Circuit Interrupters. AFCIs are located on individual breakers in modern electrical panels. Their sole purpose is to shut off the electricity to the breaker when any electrical arcing is detected.

Electrical arcing can occur from a number of reasons, such as gaps in wire insulation, frayed or damaged wiring, dust accumulation, or corrosion. If there is an interruption in the normal circuit, the electrical current might try to jump a gap to another nearby conductor. As the electricity travels through the air, it creates a bright and hot stream of plasma, which can cause fires, electrocution, and even explosions.

Needless to say, we do not want arcing to occur, which is why our friend, the AFCI, is so important. And we certainly want our AFCIs to function properly!

Square D AFCI Breaker Recall

In November 2004, Schneider Electric announced a recall on all Square D AFCI breakers manufactured between March 1, 2004 and September 23, 2004. There was a microchip in the breaker that was not reliably detecting characteristics of arcing. This was a huge safety and fire hazard, so the company had to issue replacements and refunds to any customers with these units.

At the time, around 700,000 units had been sold nationwide. Many of them were replaced, but it’s highly likely that some still remain out there.

How to Identify a Defective Square D AFCI

So how can you tell whether or not you’re looking at one of the recalled units? It helps to know the year of the home and when your current electric panel was installed. Next, make sure the breakers are manufactured by Square D.

The most noticeable characteristic of a defective AFCI will be its blue test button. If it does not have a blue button, you are in the clear. However, just because it has blue button does not necessarily mean it’s a defective model. There are certain iterations of breakers with blue test buttons that are fully functional.

The next defining factor will be its catalog number, which is located on the front under the test button. According to the Schneider Electric website the following catalog numbers are recalled:

• QO115AFI, QOB115AFI, HOM115AFI
• QO120AFI, QOB120AFI, HOM120AFI
• QO115VHAFI, QOB115VHAFI
• QO120VHAFI, QOB120VHAFI

If these numbers are illegible or faded, you can also tell by looking at the date code of the breaker. Defective date codes include:

• CN, DN, EN, FN, GN, HN, and JN.

However, the one caveat is that the date codes are located on the back of the breaker. So you will need a certified electrician to remove the breaker safely and view the date code.

Say the AFCI breaker has a blue button, but you are unable to identify the catalog number or date code. In these cases, Schneider Electric recommends that you assume that it is defective and have it replaced. You will not have to pay for the part replacement, only labor.

A garage is more than just a place to park your car or store those mountain bikes. It actually plays a significant role in the safety, security, efficiency and value of the home. However, because it is generally exterior to the living space, garage maintenance is often overlooked.

Inspecting garages is always a crucial part of our standard inspections. Our inspectors understand the importance of a well-maintained garage space, and the potential issues that can result from a neglected one.

Why Bother with Garage Maintenance?

Safety

Much like any other aspect of the house, keeping a close eye on the components of the garage will help to ensure safety. Things like faulty garage doors, exposed wiring, flammable materials, and structural damage can all lead to unsafe conditions and safety hazards.

Structural Integrity

Attached garages often share structural components with the main living space. This means that any unaddressed damage occurring to the garage foundation, slab, walls or ceiling could also directly affect other parts of the home – a prime reason to stay on top of garage maintenance!

Security

Any vulnerable or damaged parts of the garage could prove to be weak points in your home security. Intact windows and doors and properly functioning locks can prove to deter any would-be intruders.

Pest Prevention

Don’t forget about those small intruders! Garages are a hotspot for pests, such as mice, rats, birds and insects to seek refuge. And if they make their way into an attached garage, it’s that much easier for them to advance into the cozy living space. A well-maintained garage can help to keep these unwanted guests out!

Preserving Home Value

A well-maintained garage can add to your home’s curb appeal and resale value. All aspects of a property contribute to its value. This is why maintaining the garage is just as important as caring for the other lived-in portions of the home. Plain and simple – when a garage is clean, functional and secure, it looks better to a potential buyer!

Inspecting Garages: What Do Inspectors Look For?

Garage Door and Opener

The main garage door and its opener are standard parts of most homes we inspect. Our inspectors will be checking for condition, functionality and safety. The door itself should be intact and structurally sound. In addition, all of its hardware that aids it in opening and closing should be in safe, operational condition.

Electronic auto-reverse sensors on either side of the garage door are a must. These should be placed 6 inches or less from the ground and should successfully reverse the garage door when triggered. Improperly mounted or defective sensors could be a serious safety hazard, which is why our inspectors will always step through the sensors to test them.

Fire Safety

When inspecting garages, this is a big one! In the case that a fire occurs in the garage, the door into the house must act as a barrier to stop or slowdown the spread of the fire and fumes into the living space. The International Code Council (ICC) states that the door must be fire-rated, self-closing and self-latching. Additionally, there cannot be a bedroom on the other side of the door.

The inspector will also examine the walls and ceilings to make sure there aren’t any breaches or holes that could allow fire/fumes to enter the home. If the drywall is exposed, the seams should be taped and sealed (as shown below).

Electrical

Just like any other part of the house, we are going to make sure the electrical components are safe and sound. This means testing outlets to make sure that they’re properly wired and grounded.  There should also be a GFCI (ground fault circuit interrupter) present. Any exposed or damaged wiring will be called out for evaluation and repair.

It’s not uncommon to find electrical panels located in the garage, as well. In those cases, our inspectors have a whole procedure to assess the panel.

For an in-depth look at how our inspectors look at electrical panels, check out this article!

Structural Components

Similar to the electrical system, when it comes to structural components, our inspectors will treat the garage just like any other part of the home. The inspectors will look at the exterior, including siding, windows and roofing. We make sure to walk the roof when accessible. Any signs of damage, defects or deterioration will be noted.

While inside the garage, the inspector will look at the walls, ceiling, floors and attic space (when present). Does everything appear structurally sound and in good condition? Are there any signs of water damage, leaks or mold?

We also want to pay attention to cracks in the garage floor. Minor cracks are common and can occur during the concrete curing process. However, sometimes more severe cracking can be caused by factors such as soil movement or moisture intrusion, and parts of the concrete slab can heave or settle. In these cases it may be necessary for further evaluation and repair.

Pests

As stated above, pests love to make garage spaces their homes. While inspecting garages, our inspectors will be on the look out for signs of pest activity, such as droppings, nests or damage. They will also make note of any conditions that would allow easy pest entry, such as garage door gaps (shown below).

If you’re looking for a thorough pest evaluation, we offer a specialized pest inspection service. This a more extensive, top-to-bottom, search for pests throughout the property.

General Condition

When inspecting garages, we will also make note of its general condition. Is it clean and free of excessive clutter? Any items that might obstruct doorways will be flagged.

Also, if there are stairs, are they safely intact? Inspectors will check the lights to make sure they are functional.  Additionally, if there are combustible appliances, like a furnace or gas water heater, they must have sufficient ventilation. Any other noticeable defects will be noted.

As you can see, routine garage maintenance can prevent costly repairs, optimize safety, increase resale value, and give you an overall peace of mind. So when it comes to your garage – Don’t neglect. Respect!

In this day in age, electricity is a critical component in any household. The electrical panel essentially works as the heart of your electrical system – meant to safely and efficiently distribute electricity throughout the home.

During a standard home inspection, the electrical panel (often referred to as the “breaker box”) is a key focal point. When improperly installed or configured, the breaker box can be very dangerous. So what exactly does your inspector need to look for when inspecting electrical panels?

Inspecting Electrical Panels

Accessibility

Right off the bat, the inspector will be assessing the panel based on how easily it can be accessed. Obstructions will be called out, especially if the inspector can not physically get to the the box.

There should be at least 36 inches of clearance in front of the box, and 30-36 inches to its left and right. Additionally, nothing should be propped against it or stacked on top of it.

Panel Condition

The condition of the panel is crucial. Any significant defects could lead to serious safety hazards. We check for signs of water intrusion, rusting, corrosion, scorch marks etc.

Also how old is the panel? If the breaker box appears to be 30 years or older, we will call it out for further evaluation by an electrician.

There are also specific problematic brands to pay attention to. For instance, Federal Pacific (shown below), Zinsco, and Sylvania panels each had its own respective defects that proved to be serious fire hazards. If our inspectors detect these brands on the premise, they will call them out for immediate evaluation and replacement.

Proper Labeling

Our inspectors will make note of any breaker labels that are missing, incomplete, or faded. Proper labeling is important because it helps to ensure that the power is disabled correctly to any circuits or equipment while being serviced. Additionally, if any of the breakers trip, correct labeling will indicate the circuit or circuits that have been affected.

Correct Wiring and Breakers

This is a big one. During a standard inspection, our inspectors remove the panel cover in order to examine the wiring. All hot, neutral and grounds must be configured properly. And any signs of improper or hazardous wiring will surely be flagged.

A common defect we see is double tapping – where two or more conductors are connected to one breaker (shown below).  This is not allowed, and should be corrected for safety.  An electrician should evaluate and repair this item.

We are also on the look out to make sure that all the breakers are the same manufacturer as the panel itself.  Incompatibilities between breaker and panel manufacturer can cause electrical arcing and performance issues.

The breakers should be properly sized for their wiring circuits. When oversized, the wiring could overheat without the breaker tripping, creating a potential fire hazard.

We will also test AFCIs and GFCIs when they are present on the breakers. However, many older panels do not have ACFIs, and GFCIs are commonly found directly on outlets within the house.

Furthermore, it is crucial to be on the lookout for aluminum wiring. This material was widely used in the ’60s and ’70s as a cheap alternative to copper. But it soon became clear that this material is highly susceptible to corrosion and oxidization. Needless to say, this is a red flag for any inspector!

Amperage Rating

The inspector will be sure to look at the main service amperage rating, to make sure it is sufficient for the household. The average home should have at least 200 amps, with some smaller apartments only needing around 100 amps.

We sometimes see older homes with inadequate services amperages. While this may have been adequate when the home was built, this can prove to be an undersized electrical service for modern electrical needs. In these cases, the service conductors running to the home will likely need to be replaced, and the main panel will also need to be replaced with a higher capacity panel.

DIY or Non-Standard Installations

When inspecting electrical panels, any type of sloppy or seemingly unprofessional alterations or wiring may raise concern. Any improperly stripped or exposed wires will be noted. Also all unused knockouts should be covered to avoid pest or moisture intrusion.

Essentially anything that might seem out of the ordinary will likely be called out, just to be safe. When in doubt, call it out!

What Home Inspectors DO NOT Inspect

While our home inspectors can give you a comprehensive overview of the electrical system, they are not certified electricians, which means they do have limitations.

For instance, we do not remove breakers or wiring to inspect behind them. We don’t perform load calculations or test individual circuits.

If the home has an older breaker box, and you wish to verify code compliance, we will recommend that you consult with a specialist. And of course, we do not perform any repairs or upgrades.

Water is a force not to be underestimated. It can sneak its way into a home, causing structural damage, health issues, and expensive repairs. Having inspected over 66,500 homes in the span of 19+ years, we have certainly seen our fair share of mold and moisture issues.

When left unaddressed, even the smallest traces of moisture can lead to BIG issues. Whether you’re a homeowner or a property manager, understanding what leads to moisture problems—and how to prevent them—is key to protecting your investment and your (or your occupants’) health.

What Causes Mold and Moisture Issues?

Poor Ventilation

Whether we are showering, cooking or even breathing, we are constantly producing moisture. If the moisture is unable to exit the home, it can build up and lead to water-related issues and mold growth.

Leaks

Leaks are, of course, a top culprit for moisture and mold problems. Sometimes leaks are difficult to detect, as they can occur behind walls, furniture or appliances.

Without the proper attention, even the smallest leaks can amplify into huge issues. Plumbing leaks, roof leaks, and HVAC leaks are some of the leading sources for leakages.

Basement and Crawlspace Dampness

Basements and crawlspaces are naturally prone to moisture due to their location below grade. Poor drainage, water seepage through foundation walls, and high humidity levels all contribute to mold problems in these areas.

Flooding

It goes without saying that any flooding—whether from a storm, rising groundwater, or an appliance overflow—can lead to mold and other related issues.

Improperly Sealed Doors and Windows

If seals around windows or doors are failing, outside moisture can seep its way in, especially during rainstorms or in high-humidity weather.

How To Prevent Mold and Moisture Issues

As a home inspection company, we make it our job to not only identify moisture issues, but also to recommend how to avoid these problems in the future. Staying on top of maintenance and making proactive improvements can help to prevent costly repairs down the road. Let’s discuss!

Utilize Ventilation

Proper airflow and ventilation is crucial in mitigating excessive moisture buildup. Essentially, any place that produces moisture should have some type of sufficient exhaust. Having an exhaust system in your kitchen is highly recommended. This doesn’t only expel moisture from the kitchen. It also helps to pull any harmful cooking fumes out of the living space. Your clothes dryer should also be vented to the exterior for the same reason.

The bathroom is obviously a prime source for heavy moisture. You should always be mindful to run the exhaust fan when showering. It is also recommended to run the fan for 15-30 minutes after the shower in order to eliminate any moisture that may still be lingering in the air.

If you find that the home is accumulating excessive moisture, it is often advisable to install a dehumidifier. These systems can vary in size from small units for single rooms to whole house systems that regulate heat and humidity called ERV systems.

The attic space is another hot spot for moisture buildup. Proper ventilation helps the air in the attic space to circulate and alleviate any moisture accumulation or mold growth.

Monitor and Fix Leaks

This may seem like a no-brainer, but we’ve seen many cases where a small leak goes undetected and later becomes a big problem. Periodic visual inspections are a great way to avoid this type of issue. Check under your sinks from time to time, look behind the washing machine, and don’t neglect that utility closet!

We know that if you are a property manager, sometimes your tenants might not be too vigilant. That why it’s a great idea to hire a certified inspector to conduct periodic inspections.

Maintain Proper Grading and Drainage

You want to get that rain water and snowmelt as far away from the foundation as possible! That’s why having sufficient grading around the perimeter of a home is so crucial.

During a home inspection, we will always make note of any negative or flat grading. When water pools up around the foundation, it can start to seep through tiny cracks. The gradual pressure it exerts over time (known as hydrostatic pressure) can even lead to worse issues, such as bowing and structural failure.

Gutters and downspouts should also be utilized to channel water off of the roof and away from the foundation. Sometimes we will recommend downspout extensions as a way to achieve sufficient clearance.

Sump pump systems are another significant way to avoid water buildup and flooding. A properly functioning system will effectively collect any water entering into the basement or crawlspace and then discharge it away from the foundation. We always check sump pumps during our standard inspections to ensure proper functionality.

Insulate and Seal!

Believe it or not, proper insulation can help to reduce moisture issues. When sufficiently installed in a basement or attic space, insulation will minimize air exchange between the outside and interior, thus preventing excess humidity from entering the home.

Vapor barriers are also key to mitigating moisture and dampness in the crawlspace.

Essentially any opening or penetration in the home can be a potential entry point for water. That’s why windows and doors should be properly sealed and/or weatherstripped. Items such as lighting fixtures and spigots should also be sealed with necessary weatherproof sealant.

We hope that this article gave you some more insight into how to prevent mold and moisture issues. Whether you’re a homeowner or property manager, moisture control is imperative to maintaining a safe and healthy residence!

When considering a home, we often only focus on its aspects that are visible. But it is often the unseen components of a structure that play the most significant roles. One such area is the crawlspace – it plays a critically important part in the overall health, safety, and efficiency of a home. Crawlspace inspections can tell you a lot about the condition of a house, which is why they are one of the primary steps in our home inspecting procedure.

Our clients are often curious as to why the crawlspace is so important and how we go about inspecting it. So we thought it’d be a great time to break it down in a blog. Let’s discuss!

What Is A Crawlspace?

Keep in mind that not all houses have crawlspaces, so some people might not be familiar with them. For those of you who do know what they are, here’s a quick refresher.

A crawlspace is a narrow, unfinished space beneath a home, typically between the ground and the first floor. Unlike a full basement, crawlspaces are not meant for living or storage, but rather to provide access under the flooring of the home. They usually range from 1 to 3 feet in height — just enough for a person to “crawl” through.

Why Are Crawlspaces Important?

• Structural and Utility Access – As mentioned above, one of the greatest benefits to having a crawlspace is that it provides the homeowner with access to the “underbelly” of the home. Depending on the size and accessibility of the crawlspace, you can generally observe and perform and maintain important components, such as plumbing, electrical, HVAC systems and structural components.

• Moisture and Ventilation Management – Properly constructed crawlspaces help manage moisture and airflow under the house. They act as a buffer between the ground and the home’s flooring, which can prevent issues like mold growth and wood rot.

• Flood Protection – In the case that water does make its way into the building, the crawlspace helps to prevent water from entering the main living space and causing costly damage.

• Energy Efficiency: A well-insulated and sealed crawlspace can improve the energy efficiency of a home, leading to lower utility bills and a more comfortable indoor climate.

How Do We Conduct Crawlspace Inspections?

Now we’re up to speed on how important crawlspaces are. It’s no wonder then that crawlspace inspections are so important!

At Scott Home Services, we have conducted over 66,000 home inspections throughout the Colorado Front Range. Needless to say, our inspectors have seen their fair share of crawlspaces. So when it’s time to get on all fours and make our way under the house, what are we looking for?

1. Moisture and Water Intrusion

Crawlspaces have direct contact with the earth, so naturally moisture and water will want to make their way into the space. During crawlspace inspections, our inspectors are extra vigilant for any standing water, evidence of mold, and even signs of past water intrusion, such as efflorescence (powdery mineral salts that dissolve out of damp masonry). Sump pumps will also be tested for functionality (when accessible).

2. Structural Elements 

One of the benefits to crawlspaces (as stated above) is that our inspectors are generally able to see more of the home’s structural components. This means foundation wall, beams, columns, joists, etc. Any signs of cracking, deterioration, damage or settling will be noted, and we will recommend further evaluation from a structural specialist when necessary.

3. Insulation 

Depending on the age of the home, the crawlspace will generally have a varying level of insulation. For instance, newer homes usually have fully conditioned crawlspaces because they help to increase energy efficiency and reduce moisture concerns. However, in older homes, crawlspace were treated separately from the living space. So they will often have little-to-no insulation. The inspector will assess the condition and placement of the insulation, when present. In the case that the crawlspace is not conditioned, we will usually recommend converting it to a conditioned crawlspace.

4. Ventilation

Ventilation systems are an important aspect of older, unconditioned crawlspaces. These can sometimes be powered systems, but sometimes it is simply vents that allow airflow to and from the exterior. In either case, they are an important way to mitigate moisture and mold growth in the crawlspace. The inspector will make note of condition and functionality of ventilation systems, when present.

5. Vapor Barrier

The vapor barrier is a crucial element in a crawlspace. It provides added protection to the floor system from moisture or dampness that can enter from ground. So our inspectors definitely want to see one these in the crawlspace! The inspector will make note of any damage or defects, as well as missing barriers.

6. Pests

Critters such as mice, rats, spiders and insects of all shapes and sizes love to seek refuge in your cozy crawlspace. Your inspector will surely note any signs of pest intrusion, and recommend the necessary steps for remediation. We even offer a specialized pest inspection service for an even more extensive search for the unwanted guests!

7. Electrical, Plumbing and HVAC

Crawlspace access also gives our inspectors a chance to take a closer look at some of the additional components of the building. We can often examine electrical wiring, piping, ductwork, furnaces, and sometimes when present radon mitigation systems. This is also a common place that our associate inspectors will find a sewerline cleanout in order to conduct a sewer scope inspection.

We hope that this blog has given you a better understanding of crawlspaces – the unsung heroes of our homes. Thanks for reading!

Let’s face it – we need our water heaters. Whether it’s for those nice warm showers or sparkling clean dishes, most of us have our water heater working double time on a daily basis. It follows then that regular maintenance is essential for keeping your water heater running efficiently, preventing costly breakdowns, extending its lifespan, and ensuring a consistent supply of hot water. While you can certainly hire a professional to carry out periodic water heater maintenance procedures, it’s actually a very manageable process to do on your own.

Of course, both tank and tankless water heaters benefit from proactive maintenance. But due to their contrasting designs and components, their maintenance routines do differ in certain ways. Let’s discuss!

Tank Water Heaters

These are the most common type of water heater. They can either be gas powered or electric, and (as their name implies) store a large amount of water in a tank. After continual use overtime, sediment can begin to settle at the bottom of the tank causing decreased efficiency and higher energy bills. And corrosive elements in the water can attack the metal components within the tank leading to potential leaks and damage. That is why giving your heater a little TLC seasonally is so important.

Tankless Water Heaters

Contrary to tank-style, these devices heat water “on demand.” When hot water is needed, water is channeled through the heater, it is heated to a designated temperature, then off it goes to your desired location (check out the diagram below). You don’t have to worry about sediment buildup in a water tank (because there is no tank), but you do have to worry about potential mineral buildup throughout the piping and heating chamber.

Standard Water Heater Maintenance

Although tank and tankless heaters have their distinct differences, some fundamental maintenance steps apply to both:

Visual Inspection – Let’s start with the easy (and somewhat obvious) items. It’s advisable to simply check in on your water heater on a regular basis. This means giving it a visual inspection to ensure that there are no defects or leaks. If you have an older gas water heater, you can check to make sure that pilot light is ignited and burning steadily. However, most newer water heaters no longer have standing pilot lights, instead using an electronic igniter.

Be sure to look at the the combustion air intake and flue to make sure there is no damage or obstructions. Also pay attention for any strange noises or odors. And don’t forget to keep your heater and the area around it clean!

Test The Temperature – Take a look at the temperature on your water heater’s thermostat. Then, using a water or kitchen thermometer, test the max temperature coming out of your faucet. Make sure it correlates with the thermostat setting. *Note that the normally acceptable temperature range is 115ºF to 130ºF. Temperatures over 130ºF can present a scalding hazard. This picture below shows a water temp that is way too hot!

Check the TPR Valve – The Temperature Pressure Release (TPR) Valve is designed to release water if the temperature or pressure in a water tank exceeds safe levels. Without a pressure release function, the pressure can buildup inside the appliance and lead to damage, and in worst cases, a water heater explosion. So needless to say, you definitely want this thing working properly! This mechanism should be tested annually.

To test it, place a bucket under the discharge pipe and lift the valve’s tab to release some water. If water flows freely and stops when you release the tab, the valve is working correctly. If you lift the tab and no water comes out or it continues to run once closed, the valve needs to be replaced.

Now that we’ve established the related maintenance items between the two heater types, let’s examine the differences.

Before we move on, please note that in the following sections, we touch on some more advanced maintenance. These steps can normally be performed by a qualified plumbing specialist. However, if you are comfortable with more advanced DIY maintenance tasks, you may consider doing these steps on your own!

Advanced Tank Water Heater Maintenance

As we discussed above, the main defining factor of the tank-style heater is that it stores large amounts of water, and its maintenance focuses on managing sediment buildup and protecting the tank from corrosion. So how do we do that?

Anode Rod Inspection and Replacement – The sacrificial anode rod (usually made of zinc) is crucial for preventing the tank’s metal parts from corroding due to water acidity, alkalinity and bacteria. The rod attracts corrosive elements, which causes it to deteriorate, instead of the tank itself. This rod should be removed and inspected annually. Before removing it, you should first shut off the power or gas. You should also shut off the supply lines leading to and going from your water heater. 

If the rod is less than a half inch thick or has excessive mineral buildup, it should be replaced. When re-inserting the rod into the water heater, make sure to apply pipe joint compound or wrap plumber’s tape around the threads to ensure a secure seal.

Flushing the Tank and Removing Sediment – It is recommended to flush your water heater once a year, in order to mitigate the excessive buildup of sediment. Again, don’t forget to shut off the power supply or gas, and cut the water supply. In order to drain the tank, you must connect a hose to the drain valve at the bottom of the tank.

You can drain the water into a bucket or a nearby floor drain, if available. Once empty, close the drain valve, add a gallon of vinegar, and let it sit for several hours. Afterward, fill the tank back up with water, and subsequently drain the water/vinegar mixture out of the tank.

Finally, once the tank is completely flushed, you can seal up the drain valve and fill the tank back up. Make sure you turn on a faucet in the house so that any excessive air pockets can escape the tank and water lines.

Advanced Tankless Water Heater Maintenance

As stated above, tankless-style water heaters with not have the issues that come along with stored water. Their primary maintenance focus is on preventing and removing mineral scale buildup within the heating chamber and pipes.

Descaling and Flushing the System – Tap water contains minerals like calcium and magnesium that can build up on and erode the walls inside the water heater, blocking water flow and decreasing efficiency. Therefore, it is recommended to flush your appliance at least once a year (maybe even every 6 months if your water supply is significantly hard).

We can’t say it enough – make sure to cut off the gas or power before flushing out your system! You should also close the water lines to and from the heater before servicing. Next you will want to connect a hose to each service valve (shown above). The hose attached to the “cold water in” line should connect to a submersible pump in a bucket, and the hose attached to the “hot water out” line should be emptying into the same bucket.

Add about 3 gallons of descaling solution or white vinegar to the bucket, then turn on the pump to circulate it through the appliance. This process should continue for 30 minutes to an hour. When the flush is complete, seal up the service valves, open the supply valves, and turn the power or gas back on.

Cleaning Water and Air Filters – Most tankless units will have water and/or air intake filters, as well. These should be inspected and cleaned or replaced every 6 months.

Inspecting Water Heaters

Water heaters are one of the big ticket items we look at during our standard home inspections. Our inspectors understand the importance of these systems, and give them the thorough evaluations they deserve.

First of all, we are going to conduct a visual inspection. Any signs of damage or leaking will certainly be noted. The inspector will check for any apparent corrosion, and whether or not a TPR valve is present with a properly sized discharge pipe.

We also want to know if the water is being properly heated. The inspector will test the max temperature of the water from a faucet inside the house, making sure it correlates with the settings on the water heater thermostat. If there are noticeable issues that aren’t apparent from a visible inspection, the inspector will recommend further evaluation from a plumbing specialist.

Our inspectors also want to make sure the environment around the heater is safe and free of any harmful fumes. So they use specialized tools to check for gas leaks at the gas supply lines. They also to make sure the exhaust is exiting the living space properly through the flue by testing for carbon monoxide (as shown below).

The average residential home has a lot of vents – vents for your HVAC system, vents for your attic, a vent for your dryer, a vent for your gas water heater etc. But did you know that your plumbing system also needs vents? In fact, reliable plumbing ventilation is absolutely crucial for a healthy and functioning plumbing system.

What Is Plumbing Ventilation?

Plumbing vent pipes are a network of pipes that extend from your drain lines, up and out through your roof. Their primary role is to regulate the air pressure within your plumbing system. Think of them as the lungs of your home’s plumbing – and without the proper amount of air, your plumbing system cannot “breathe” properly.

Plumbing vents have two primary jobs:

1. They regulate pressure within the pipes and ensure the proper flow of water and wastewater.
2. They serve as an escape route for odorous and potentially harmful sewer gases, keeping your home safe and free of unpleasant smells.

How Does Plumbing Ventilation Work?

Plumbing vents work by maintaining a neutral air pressure within your drain pipes. When water flows down a drain, it creates negative pressure behind it. Without a vent, this negative pressure could create a vacuum, hindering the flow of water, causing slow drainage and even backups.

Improper airflow can also potentially siphon water out of your P-traps. P-traps are the U-shaped bends (shown below) found under virtually every drain in your house. These small segments of piping hold a small amount of water that acts as a seal that blocks sewer gases from backing up into your home.

Without adequate airflow, negative pressure can pull the water out of the P-trap. Now, with no water barrier present, gases and odors can make their way back through your pipes and into the house. That is obviously something no one wants!

In addition to promoting airflow, these vents provide a pathway for gases, such as hydrogen sulfide and methane, to safely escape above the roofline and away from your living spaces. This dual action of airflow and gas release is essential for a well-functioning and odor-free plumbing system.

Common Issues Associated with Insufficient Plumbing Vents

In order to function properly, vent pipes must remain open. So it follows that they can occasionally become damaged by exterior elements, or clogged by debris such as leaves, animal nests, dirt, ice, or snow. Without the proper ventilation, it is likely you will experience some of the following symptoms:

• Sewer Odors – If vents are blocked or damaged, sewer gases cannot escape properly and may be forced back into your home through drains.
• Slow Drainage –  Blocked vents mean no airflow in the plumbing system, hindering the ability of drains to empty quickly.
• Gurgling Sounds – Gurgling sounds in drains or bubbling toilets is a tell-tale sign that you may have air pressure problems in your pipes.
• Ineffective Flushing – Without proper ventilation, liquid will not exit the toilet as quickly as usual. In some cases, the toilet might not drain at all.

Inspecting Plumbing Ventilation

Our home inspectors are not plumbers. However, during our standard home inspections, there are a number of ways we can inspect your plumbing system. Our inspectors always walk the roof, when accessible. In the cases that roof access is available, the inspector is able to look at each vent, searching for any signs of damage or obstructions. During winter months (if the roof is walkable), inspectors will check to make sure there is no snow or ice buildup within the vents.

During the interior portion of the inspection, we always run all sinks and flush all toilets to test functionality. Inspectors will take note note of any abnormally slow drainage. Of course, this could mean there is some type of backup or clog in the plumbing. But it could also mean that there is a ventilation issue.

As stated above, strange sounds such as gurgling or bubbling could indicate poor venting. So the inspectors will make sure to listen closely for anything out of the ordinary.

Let’s not forget to use our noses! Our inspectors will certainly be vigilant for any unusual or foul smells and make note of it in the report. This could definitely indicate ventilation problems.

However, sometimes smelly odors just means that the P-trap has dried up. We see it a lot in vacant properties. If water has not been run through piping over an extended period of time, the liquid in the P-trap can evaporate, allowing gases to make their way into the living space. This can often be fixed by simply running water through the piping periodically.

When issues do arise, sometimes it’s hard to pinpoint exactly what’s going on. It may be best to look inside the plumbing. That’s why we offer sewer scope inspections. During this specialized inspection, we run a camera through your drainage system to examine its current condition and try to identify any issues that may be present. If/when we do identify a problem, our inspector will recommend further evaluation or repair by a qualified plumbing professional.

Conclusion

While they often remain out of sight and out of mind, plumbing vents are essential for a healthy and functional home plumbing system. Understanding their role and being aware of potential issues will help you keep your drains flowing smoothly and your home smelling fresh. Regular maintenance, such as periodically checking your vents, clearing vent openings, and pruning nearby trees etc. can help prevent serious venting issues from occurring down the road.  So be kind to those pipes sticking out of your roof, and remember the vital work they are doing behind the scenes!
