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.

As one of the leading rental inspection companies in Colorado, our inspectors have conducted hundreds of rental inspections throughout Denver. Needless to say, we’ve seen a lot of different properties. And one of the most common defects we come across is an unsafe or improperly configured exterior door deadbolt lock.

This often comes as a surprise to clients who are confused as to why a perfectly functional deadbolt would fail a rental inspection. So what are the deadbolt requirements for passing a Denver Rental License Inspection? Let’s unlock the truth!

The Denver RRP – All About Safety

If you are a Denver property owner or manager, you are probably quite familiar with the Denver Residential Rental Program (or RRP) and the licensing it requires. Recall that the program was implemented as a way to ensure minimum safety standards for all Denver renters. The inspector utilizes the city’s Inspection Checklist, which is broken down into several important sections, as shown below.

Section 1 – Egress makes it a requirement for every dwelling to “have a means of egress leading to a safe and open space at ground level.” This is where the deadbolt discussion comes into play.

Check out this article for a full breakdown of the Inspection Checklist.

Why Do Deadbolt Requirements Matter?

There is a large number of older homes in Denver with exterior doors or security doors with deadbolt locks that are keyed on the inside (i.e. you need a key to lock/unlock them from the inside). This may seem like a perfectly viable means to exit the property. However, this will always be flagged as an inspection fail.

We know the key to that deadbolt lock is likely present and accounted for. In fact, some tenants even leave the key in the deadbolt for convenience. So you might be thinking – why is this an issue?

You need to consider the worst case scenario. What would happen in an emergency if the tenant needs to exit, and the key is somehow missing? All of a sudden you have a serious safety hazard that could be life threatening. And for that reason, these types of deadbolts are non-compliant items.

Deadbolt Requirements to Pass a Rental Inspection

In the case that you do have a keyed-on-the-inside deadbolt lock, our inspectors will require it to be switched out to a hand turn lock (like the one shown above). If the defective door in question is an outer security door, you can also opt to remove the lock all together (variations shown below).

You may notice that, if you reference the Inspection Checklist Guidebook, it does not explicitly mention deadbolt requirements. However, section 1.1 C states the following:

C. Doors, windows, corridors, stairways, fire escapes, and passageways, serving as ordinary or emergency exit routes shall be free of stored, discarded, or extraneous material, and in no case shall these routes be obstructed or locked to persons within the dwelling.

This excerpt essentially states that any feature obstructing an individual from unlocking and exiting the premise is an inspection fail. And according to the city, that includes keyed-on-the-inside deadbolts. We even personally verified this with city officials. So make sure to keep your property safe and update those deadbolts!

We hope this article has cleared things up with regards to deadbolt requirements. If you have any questions, feel free to contact us through our Ask Your Inspector program. Or you can reach out directly to the city of Denver at licenses@denvergov.org.

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!

In this day and age, energy efficiency is more important than ever. Building codes have grown stricter with the goal to reduce energy consumption, stimulate sustainability, and increase long-term savings. We needed a way to standardize these code requirements, which is why different energy efficiency ratings have been developed over recent years. But with so many ratings and certifications— like HERS, ENERGY STAR, DOE Zero Energy Ready Home, and the newer ENERGY STAR NextGen— understanding what each one means can get confusing! In this article, we will compare and contrast each of the primary energy ratings systems to help clear things up.

HERS Ratings

This is one of the flagship energy services that we offer at Scott Home Services. Developed by the Residential Energy Services Network (RESNET), the Home Energy Rating System (HERS) is a scoring system that measures the energy efficiency of a home. This is nationally recognized method to meet IECC energy code standards in many municipalities.

During the HERS rating process, the home is assessed based on a list of criteria including:

• Insulation Levels
• HVAC Systems
• Windows and Doors
• Ductwork
• Air leakage (Blower Door Test)
• Water heating
• Solar/renewable energy use (if applicable)

A certified home rater performs a full energy rating on the home by analyzing aspects listed above using a specialized software. The results of the data analysis are compared against a “reference home,” and a resulting HERS score is created.  A lower score means the home is more comfortable and energy-efficient. So the lower the score, the better.

ENERGY STAR

ENERGY STAR is a program implemented by the US Environmental Protection Agency (EPA) as an initiative to “protect the environment, improve air quality, and protect public health.”

In order to be branded with that recognizable blue logo, a home must be evaluated by a certified ENERGY STAR rater. A HERS evaluation is included as part of the qualification process. The home must meet a predetermined HERS score (based on several factors like climate zone, house size, etc.), and also meet strict standards for:

• High- performance insulation, doors and windows
• Efficient HVAC systems and ducts
• Proper air sealing and ventilation
• Energy Star-rated lighting and appliances

DOE Zero Energy Ready Home (DOE ZERH)

DOE ZERH, which was established by the US Department of Energy, is a type of certification that signifies an extremely high performance home. This is meant to build upon the already stringent ENERGY STAR rating.

The difference is that these homes must either have solar installed to meet net zero energy usage, or have solar-ready infrastructure installed to be able to reach net-zero energy usage. Additionally they must have a stricter focus on indoor air quality, utilizing the EPA’s Indoor airPLUS guidelines.

Indoor airPLUS is a program designed to “improve the quality of indoor air by outlining construction practices and product specifications that help minimize exposure to airborne pollutants and contaminants.” Learn more about it here.

With all of these sustainable features in place, the house should have the infrastructure in place to offset most, if not all, of its energy usage with photo-voltaic solar. If the homeowner opts to install the solar needed, the house can achieve net-zero energy usage (or close to it), hence the name of the certification.

ENERGY STAR NextGen

Just when you thought a home couldn’t get any more energy efficient, out rolls the ENERGY STAR NextGen program in 2024. This is the strictest of all the energy efficiency ratings. It incorporates all the standards of the ENERGY STAR, but also emphasizes a focus on electrification, decarbonization, and grid-interactive technologies. Requirements include:

• High-efficiency electric heating and cooling
• Electric water heating
• Wiring for electric vehicle charging
• Induction cooking technology
• High indoor air quality
• Solar readiness
• Smart grid capabilities (for demand-response and time-of-use optimization)

This process can certainly be costly for the homeowner and difficult for the contractors while building . However, the end product can prove to have multiple benefits such as significantly lower energy bills, smaller. carbon footprint, improved indoor air quality, reduced noise, and even increased resale value!

Check out the table below 👇 to see how each of the energy efficiency ratings differs.

Need Energy Services?

Whether you need to meet your local building minimum code requirements, or you are striving for an ENERGY STAR NextGen certification, you’ve come to the right place! Because all 4 of the energy efficiency ratings discussed above are structured on the HERS ratings – a service we offer!

We can help you with virtually every step in the process. We proudly offer a whole list of energy services – including HERS Testing (projected, mid-construction and final), Blower Door Testing, Insulation Inspections, Air Barrier Inspections and Duct Leakage Testing – to help you reach whatever energy goals you may have.

Furthermore, our Energy raters are also ENERGY STAR certified. So if you are striving to meet the ENERGY STAR, DOE ZERH, or ENERGY STAR NextGen qualifications, our specialists can aid in evaluation and verification.

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).

Are You In Need of a Home Inspection?

If you are closing on a home in the Colorado Front Range, we hope that you will consider Scott Home Services for your home inspection services! Feel free to visit us online to learn more or contact us to schedule your inspection services today!

Let’s face it – there are a lot of critters in Colorado. Mice, rats, bats, birds, raccoons, termites, spiders and insects of every shape and size are all out there looking for a cozy place to call home.

When you’re purchasing a home, the last thing you want is to find some unwelcome guests shacking up with you and your family. Pests and insects can cause significant property damage and even pose health concerns. That’s why it’s never a bad idea to call in a specialist for a pest inspection before closing.

Where Do We Conduct the Pest Inspection?

At Scott Home Services, our pest inspection is a complete visual review of the structure and foundation of the home. We follow the guidelines created by the National Pest Management Association and the NPMA-33 inspection procedure.

Our inspectors access and examine all readily accessible areas where pests and wood destroying insects might be a concern. Essentially, our pest inspectors will follow the same path as a standard home inspection. However, their sole focus is, of course, pests. The areas we inspect include:

• Exterior and Grounds
• Roof
• Crawlspace
• Basement
• Attic
• Garage
• Interior
• Additional Structures (sheds, outbuildings etc.)

What Pests Do We Inspect for?

Wood Destroying Organisms (WDOs) – This is a category of insects that feeds on wood, which includes termites, carpenter ants, carpenter bees, and wood boring beetles. Being that most homes have certain wood components, these critters can pose a serious threat to structural integrity.

Due to the relatively dry climate of the Colorado Front Range, our inspectors don’t come across WDOs very often. But we do find them from time to time, and we make sure to always stay vigilant for signs of WDOs.

This means inspecting the property for any evidence of live or dead WDOs. Our inspectors will also take note of any damaged wood, tunneling, termite mud tubes, or frass (tiny fecal pellets that several WDOs commonly leave behind).

Unfortunately, much of WDO damage may be hard to identify, as it occurs behind walls. So when we do detect any signs of WDO activity, we will recommend further evaluation from a specialist.

Rodents –  Rodents, especially mice and rats, are very common home intruders in Colorado. They like to shack up in less busy parts of the house, such as basements, crawlspaces and attics.

Our inspectors will always inspect the nooks and crannies of the premise looking for signs of rodents. The most prominent clue is droppings, but we will also often find signs of nesting or rodent trails in insulation.

Whenever we discover a significant presence of mice or rats, we always recommend consulting with a pest control company. Although they might look cute, these rodents can cause costly damage and unsanitary conditions.

Birds –  These critters are primarily nesting in certain parts of the roof and gutter systems or under decks. But we have also found them in less common locations such as chimneys or attics. Birds can also cause damage and make unwanted messes.

Wasps – It is very common to see wasp nests a the exterior of homes, especially under overhangs and soffits. This is generally a maintenance item, and we will recommend removal from a pro, as needed.

We also occasionally see wasp nests located inside the home, usually the attic. This can be more concerning, being that it is in the living space, and removal is recommended.

Other Insects – No matter how airtight your home is, bugs will somehow find a way inside. We see a lot of spiders, flies, ants, etc. While these types of pests aren’t usually much of a concern, our inspectors will make note for removal or extermination as needed.

Additional Animals – Having been conducting inspections for almost 20 years, our inspectors have seen quite the spectrum of animals in homes. Raccoons, bats, snakes, squirrels to name a few.

If our inspectors don’t actually see the pest, they can generally identify them by their droppings, and will recommend further evaluation when necessary.

How To Prevent Pest Intrusion

At Scott Home Services, we are all about setting our clients up for success. That’s why, during our pest inspections, we don’t only identify existing pest issues. We also make note of the ways that you can prevent future pest intrusion!

For instance, any holes, cracks or openings will be noted. This includes gaps in weather stripping, garage door gaps, holes or damage in screens, openings at penetration points, gaps at the eaves and all other vulnerable areas.

Many insects thrive in damp conditions (including subterranean termites), so we call out any moisture concerns around perimeter. In addition, our inspectors will mention any grading issues or improperly installed gutters that could promote moisture build up.

We all know that WDOs love wood, and any wood piles in contact with the home will be called out for relocation. Subterranean termites also love when they have access to wood sources directly from the soil – so we call out any siding or deck components that are in contact with soil.

Also make sure to trim back those bushes and trees! They may look pretty, but foliage in contact with the home or overhanging the roof (as shown below) give pests an easy route to access the home.
