The Crucial Importance of Identifying Federal Pacific Electrical Panels in Home Inspections
When it comes to ensuring the safety and reliability of electrical systems in a home, few components demand as much attention as the electrical panel. At Double H Inspections, one of our critical focuses during a home inspection is identifying Federal Pacific Electrical (FPE) Panels. These panels, once widely used across the United States, have been found to pose significant safety risks. Let’s explore why these panels are a red flag during home inspections.
The Legacy of Federal Pacific Electrical Panels:
Federal Pacific Electric Company was a popular manufacturer of electrical panels installed in millions of homes from the 1950s to the 1980s. Initially celebrated for their affordability and availability, these panels later became notorious for their safety issues. (Crazy I know but the “cheaper” option on something as important as your electric panel probably isn’t the best idea).
- Faulty Breakers: Research and real-world incidents have revealed that FPE Stab-Lok breakers often fail to trip in case of an overload or short circuit. This failure can lead to electrical fires, posing serious risks to homeowners.
- Incorrect Labeling: Some FPE panels were found to be improperly labeled, potentially misleading electricians and homeowners about the safety and capability of these panels.
- Recall and Litigation: The issues with FPE panels led to widespread recalls and litigation, highlighting the risks associated with these panels.
Why We Call Them Out:
At Double H Inspections, our priority is the safety and well-being of our clients. During inspections, we specifically look for FPE panels for the following reasons:
- Prevention of Electrical Fires: Identifying and recommending the replacement of FPE panels can significantly reduce the risk of electrical fires.
- Compliance with Safety Standards: Modern electrical standards and practices have evolved, rendering FPE panels obsolete and non-compliant.
- Ensuring Peace of Mind: Informing potential home buyers about the presence of FPE panels helps them make informed decisions and plan for necessary upgrades.
In conclusion, the identification of Federal Pacific Electrical Panels during a home inspection is more than a mere technicality; it’s a crucial step in ensuring the safety and integrity of a home’s electrical system. At Double H Inspections, we are committed to thorough inspections that protect our clients and their investments. Remember, when it comes to electrical safety, knowledge is power, and awareness is the key to prevention.

Understanding Ice Dams in Wyoming: Causes, Effects, and Prevention
- Nov, 10 2023
Welcome to the Double H Inspections blog! As residents of Wyoming, many of us are no strangers to the challenges that winter brings. One such challenge, particularly relevant to homeowners and potential home buyers, is the formation of ice dams on roofs. In this blog, we aim to shed light on what ice dams are, why they occur, the problems they can cause, and most importantly, how they can be prevented and treated.
Ice dams are ridges of ice that form at the edge of a roof and prevent melting snow from draining off. They typically occur when the roof warms enough to melt the underside of the snowpack. The melted water flows down the roof surface until it reaches the cold overhang, where it refreezes, creating an ice dam. In Wyoming, with our cold winters and frequent snowfall, conditions are often ripe for these icy blockades.
Several factors contribute to the formation of ice dams. Key among them is poor attic insulation and inadequate ventilation. When heat escapes through the roof, it melts the snow directly on the roof surface. This problem is compounded in areas like Sheridan, Wyoming where temperature fluctuations and heavy snowfall are common.
The implications of ice dams can be serious. They can tear off gutters, loosen shingles, and lead to water seepage into your home. This water intrusion can damage ceilings, walls, insulation, roof decking and framing, and can even foster mold growth. Addressing ice dams is crucial in maintaining the structural integrity of your home.
Preventing ice dams starts with improving attic insulation and ventilation. This reduces the amount of heat escaping through the roof, thus preventing the melting and refreezing cycle. Regularly clearing snow from your roof can also help, as can ensuring your gutters and downspouts are clear and in good repair. Using heat cables should be a last-ditch effort as they are a bandaid and typically not a full solution. Sometimes older homes don’t allow for proper improvements without significant remodeling costs do to their architecture. In these cases, heat cables may be the only feasible option. If you use heat cables we recommend having a professional install thermal-regulated commercial-grade cables, they are much more effective than the cheaper residential models sold in box stores.
If you already have ice dams, it’s important to remove them carefully. Using tools like hammers or chisels can damage your roof. Instead, try using calcium chloride ice melt. For safety and effectiveness, consider hiring professionals for ice dam removal.
Every home is unique, and sometimes specific solutions are needed. Consulting with home inspection professionals, like those at Double H Inspections, can provide personalized advice and solutions. Upgrades or repairs to insulation and ventilation systems can also offer long-term relief. Not only that but you will improve the overall thermal efficiency of the home and save on heating and cooling costs. You are replacing damage from ice dams you might spend thousands of dollars on with upgrades to the home that over a lifetime will save you thousands.
Ice dams can be a persistent problem in Sheridan, Wyoming, but with the right knowledge and approach, they can be effectively managed and prevented. Remember, the key is to be proactive – regular maintenance and timely intervention can save a lot of trouble down the line.
If you’re concerned about ice dams or want more information on protecting your home this winter, don’t hesitate to contact us at Double H Inspections. We are ready to help you with all your home inspection needs.

Fall Home Maintenance Tips to Protect Your Wyoming Home
- Oct, 21 2023
As the leaves change colors and the air becomes crisper in Wyoming, it’s a clear sign that fall has arrived. While many may be thinking about cozy evenings by the fire and enjoying the beauty of the season, homeowners need to remember that fall is also the perfect time to prepare their homes for the upcoming winter. Seasonal home maintenance not only protects your investment but also ensures a safe and comfortable living environment. In this article, we’ll provide you with essential fall home maintenance tips for your Sheridan, Wyoming property.
1. Clean Your Gutters: As the leaves fall, they tend to accumulate in your gutters, potentially causing blockages. Clearing your gutters of debris is crucial to prevent water damage during winter rains and snowmelt. Also, make sure your downspout extensions are on and diverting water at least 4′ away from your home. This can be a dangerous task as over 50,000 people are sent to the emergency room each year for falls while cleaning their gutters. You should consider hiring a contractor or handyman to perform this task and keep yourself safe.
2. Check Your Roof: Inspect your roof for loose or damaged shingles and have any necessary repairs done. Ensure there are no leaks, as winter precipitation can exacerbate existing issues. This is another task best served by a qualified contractor, or even better, a qualified inspector. I have spent over a decade in the roofing industry and I am an Internachi certified roof inspector. I can come give you a non-biased, non-sales related, unbiased opinion of the condition of your roof and if it needs repairs, upgrades, or replacement.
3. Seal Gaps and Cracks: Seal gaps and cracks in doors, windows, and any other openings in your home to prevent drafts and heat loss. This helps to maintain a comfortable indoor temperature and save on heating costs. Also sealing cracks in your driveway and walkways can help prevent further damage and deterioration from water and ice this winter.
4. Service Your Heating System: Before the temperatures drop, schedule a professional inspection and maintenance for your heating system. A well-maintained furnace or heating system runs more efficiently and is less likely to break down during the cold season. If you skip this important maintenance item Murphy’s Law is likely to rear its ugly head on a freezing cold weekend this winter costing you big time for an after hours emergency service call. Change that air filter too!
5. Fireplace and Chimney Maintenance: If you have a fireplace, ensure that it’s clean and the chimney is clear of debris. A professional inspection may be needed to identify and address potential issues.
6. Inspect Insulation: Check the insulation in your attic. Adequate insulation is essential for retaining heat and preventing ice dams on your roof. If you have had ice dams in the past you are almost assuredly lacking proper insulation and possibly proper ventilation in your attic. Get this looked at ASAP to prevent damage to your home this winter as well as same some money. Upgrading your attic insulation is one of the best returns on the money you can get in home improvements. The heating and cooling savings are noticeable instantly.
7. Test Carbon Monoxide and Smoke Detectors: Your safety is paramount. Test your carbon monoxide and smoke detectors, and replace batteries if needed. If your smoke detectors are yellowing that means its time to replace them. For more information on locations and best practices check out this link: https://www.nfpa.org/Public-Education/Staying-safe/Safety-equipment/Smoke-alarms/Installing-and-maintaining-smoke-alarms
8. Lawn and Garden Care: Prepare your yard for winter by aerating, fertilizing, and protecting plants. Trim trees and shrubs away from the house to prevent damage during heavy snowfalls. Cut your grass one last time a little shorter than normal for winter.
9. Drain and Store Outdoor Hoses: Disconnect garden hoses, drain them, and store them indoors to prevent freezing and damage. This is a huge one that can cause massive damage if skipped. Leaving a hose hooked up can freeze and break your exterior spigot or the plumbing behind it. This can lead to flooding of your home, don’t skip this step!
10. Schedule a Home Inspection: Consider hiring a professional home inspection service, such as Double H Inspections, to thoroughly evaluate your property. A home inspection ensures that no hidden issues are lurking, potentially saving you from costly repairs in the future. Most people don’t do a thorough evaluation of their property, let alone annually. If you are one of these people then it’s a good idea to get a home inspection just to find out the condition of all aspects of your home and get a list of repairs and upgrades you may need to make. To help more people get this done I am offering 25% off any general home inspection for non-real estate transaction purposes to anyone who mentions this newsletter when booking.

Whether you’re purchasing a pre-owned home or constructing a new one, a comprehensive inspection by experts like Double H Inspections can be the key to unlocking a future of safety and peace of mind.
Why a Home Inspection?
1. Uncover Hidden Issues:
Purchasing a home is not just about what meets the eye. Structural, electrical, plumbing, and other hidden issues may lurk beneath the surface. A professional home inspection acts as a detective, uncovering potential problems that could turn into costly repairs down the line.
2. Negotiating Power:
Armed with the insights from a detailed inspection, you gain negotiating power. If issues are identified, you can work with the seller to address them before finalizing the deal or negotiate a fair price based on the necessary repairs.
3. Protect Your Investment:
A home is one of the most significant investments you’ll make. Protect that investment by ensuring that the property is in sound condition. Identifying issues early can prevent small problems from escalating into major headaches.
Double H Inspections: Your Trusted Partner in Home Safety
At Double H Inspections, we understand the importance of a thorough and accurate inspection. Our team of certified inspectors is dedicated to providing comprehensive assessments to give you the confidence you need in your real estate transactions.
Services Offered by Double H Inspections:
1. Home Inspections:
Our standard home inspection covers every nook and cranny of the property. From the foundation to the roof, we leave no stone unturned to ensure that you have a complete understanding of the home’s condition. If it is visible and accessible on the date of inspection we are going to make sure it’s in proper operating condition.
2. New Construction Inspections:
Even new homes can have hidden issues. Our new construction inspections ensure that your dream home is built to the highest standards, identifying any potential concerns before they become major problems. I know you think you don’t need an inspection because it passed a city inspection or because it’s brand new. However, houses are built by people and people make mistakes. I have yet to inspect a home where I did not find enough defects that the cost to correct those issues was less than my inspection cost. If you are on the fence about a new construction inspection, go read some of my Google reives from customers who were more than happy they didn’t skip this inspection.
3. 11 Month Warranty Inspections:
Did you skip the new construction inspection, or didn’t know about it? Well, you are in luck. We offer an 11-month warranty inspection so that you have a professional inspector find any defects in the home that should be repaired by your builder prior to your builder’s warranty expiring. You’ve waited long enough, hurry up and book your 11-month warranty inspection today!
4. Radon Testing:
Radon is a silent threat that can go unnoticed. Our radon testing services help you identify this colorless, odorless gas, ensuring the safety of your family. Click here for more information on Radon and the dangers it poses.
5. Sewer Scopes:
Sewer lines are a hidden component of a home that can cost you big time if it’s not in proper working condition. Add a sewer scope to your inspection, or as a stand-alone service, to make sure you aren’t hit with an expensive repair you weren’t expecting. This is especially important for homes built in the 1970s or older.
6. Septic Inspection:
Septic systems are a major part of many homes especially those in the county or rural properties. We can perform a septic inspection during a home inspection by having a pump truck pump out the tank for a visual inspection as well as running a sewer scope from the house to the tank to ensure everything is functioning properly.
7. Water Testing:
Want to make sure your drinking water is safe? Is the property on a well and you need a test for your FHA loan? Are you interested in knowing exactly what is in the water you drink every day from your home? Well, we have the answer for you. Our 3 levels of water quality testing range from basic bacteria and mineral testing to the most compressive including well over 150 specific items being tested across the categories of bacteria, metals and minerals, anions, attributes, radioactive chemical elements, industrial & cancer-causing chemicals, semi-volatile organic compounds (SVOCs), and herbicides/pesticides.

Radon – what you need to know!

Unseen Threats: Understanding and Mitigating the Health Risks of Radon in Your Home
In the realm of home safety, some threats are invisible but potentially lethal. Radon, a colorless and odorless gas, is one such danger that can seep into homes, putting occupants at risk of serious health issues. At Double H Inspections, we believe that knowledge is the first line of defense against unseen threats. In this blog post, we’ll delve into the health risks associated with radon, shed light on the importance of testing, and highlight how our advanced testing methods set us apart in ensuring your home’s safety.
Radon is a naturally occurring radioactive gas that forms from the decay of uranium in soil and rocks. It can enter homes through the ground, and in enclosed spaces, radon can accumulate to dangerous levels. Prolonged exposure to elevated radon levels is a significant health concern, as it is the SECOND LEADING CAUSE OF LUNG CANCER after smoking, according to the World Health Organization (WHO).
Health Risks of Radon Exposure:
The health risks associated with radon are alarming. According to EPA estimates approximately 21,000 people die from radon-related lung cancer every year in the United States. Long-term exposure to elevated radon levels can significantly increase the risk of lung cancer. Radon decays into radioactive particles that, when inhaled, can damage the lung tissue over time. Smokers exposed to radon are at an even higher risk of developing lung cancer, making it crucial for both smokers and non-smokers to be aware of radon levels in their homes.
(2005) Two studies show definitive evidence of an association between residential radon exposure and lung cancer. Two studies, a North American study, and a European study, combined data from several previous residential studies. These two studies go a step beyond earlier findings. They confirm the radon health risks predicted by occupational studies of underground miners who breathed radon for a period of years.
Early in the debate about radon-related risks, some researchers questioned whether occupational studies could be used to calculate risks from exposure to radon in the home environment. “These findings effectively end any doubts about the risks to Americans of having radon in their homes,” said Tom Kelly, Former Director of EPA’s Indoor Environments Division. “We know that radon is a carcinogen. This research confirms that breathing low levels of radon can lead to lung cancer.”
Radon Levels and Recommendations:
According to Airthings, a leading provider of radon detection devices, the recommended action level for radon is 4.0 pCi/L . The WHO suggests that even lower levels, starting from 50 Bq/m³, can pose health risks. Wyoming, known for its unique geological features, is prone to higher radon levels. The Wyoming Department of Health emphasizes the importance of testing for radon to ensure a healthy living environment.
To grasp the significance of radon gas levels, let’s dissect the interpretations of radon readings:
Minimal Levels (Up to 1.3 pCi/L): concentrations below 1.3 pCi/L are considered safe radon levels, necessitating no immediate action. Nonetheless, continuous monitoring is prudent.
Low Levels (1.3 to 2.6 pCi/L): levels falling within this range are classified as acceptable radon levels. While immediate intervention is not imperative, regular monitoring is advisable. Additionally, homeowners can experiment with ventilation and sealing foundation cracks as a preventive measure.
Moderately High Levels (2.7 to 4 pCi/L): levels between 2.7 and 4 pCi/L are considered moderately high, warranting attention. Initial steps may involve enhancing ventilation and monitoring the situation. If no improvement is observed after three months, it is advisable to consult a professional radon mitigator.
Risk Levels (Above 4 pCi/L): levels exceeding 4 pCi/L (150 Bq/m3) for more than 1 month are deemed high, demanding immediate action. In such cases, homeowners should promptly seek for professional radon mitigation to address the radon problem.
Average readings in our area: Over the past year the average readings in our area for tests performed by Double H Inspections have been 6.3 for homes with basements and 5.4 for homes with crawlspaces. As you can see both homes on basements and homes on crawlspaces are prone to high levels of radon in our area. I hear from potential customers all the time that because they have a crawlspace vs. a basement they don’t need a radon test. That simply is not true, the environmental/geological factors below the soil have far more impact on your home’s radon levels than having a crawlspace vs. a basement.
Why Test for Radon with Double H Inspections?
At Double H Inspections, we prioritize your safety and well-being. Our advanced radon testing method utilizes the Airthings Corentium Pro, a state-of-the-art device designed for precision and reliability. Unlike traditional charcoal tests, the Corentium Pro provides real-time, continuous monitoring of radon levels. This allows us to capture fluctuations and variations in radon concentration, offering a more accurate and comprehensive assessment of your home’s safety. The monitors also track temperature, humidity, barometric pressure, and movement. These help the inspector better determine why certain readings may exist or if the unit has been tampered with.
The Airthings Corentium Pro Advantage:
Accuracy: The Corentium Pro employs advanced technology to ensure precise and reliable measurements, offering a more accurate assessment of radon levels in your home.
Real-time Monitoring: Continuous monitoring allows us to capture fluctuations and variations in radon concentration over time, providing a more detailed picture of potential risks.
No Lab Delays: Traditional charcoal tests require laboratory analysis, which can lead to delays in obtaining results. With the Corentium Pro, we can provide you with immediate, on-site results, enabling prompt action if elevated radon levels are detected.
In the quest for a safe and healthy home, addressing unseen threats like radon is paramount. Double H Inspections is committed to empowering homeowners in Wyoming with the knowledge and tools needed to ensure the safety of their living spaces. By choosing our services you are taking a proactive step towards safeguarding your home and the well-being of your loved ones.

Spring Maintenance Saves You Money
- Apr, 10 2022
Why spring maintenance is important to your home and can save you money over time.
All the components of your home are slowly failing. From the day they were installed they began the slow breakdown that leads to failure at some point in the future. Your roof, siding, windows, floors, HVAC, electrical systems, appliances, you name it in your home and it is working toward failure. Obviously, some things fail sooner than others but make no mistake everything is slowly failing.
So what do you do about it? Well, one of the most important things you can do is perform maintenance to your home and its systems to help extend their useful life. With proper upkeep, most items in and around the home will last much longer than those that are neglected. I have put together a brief summary of some important items and systems to make sure maintenance is performed on this spring. Some of these are easy homeowner jobs and others should have a professional do the work. If you’re not sure hire a pro the first year, if it looks easy enough then next year you can try it.
- Clean out your gutters.
- This one is a huge one that is largely overlooked far too often. Clogged gutters can lead to gutters pulling away from the fascia, rotted fascia and soffits, and over time improper drainage that can lead to foundation issues. There are lots of tools out there to help with this task to make it safe. Hire a handyman or roofer if you can’t clean them from the ground.
- Inspect your roof.
- This one can be dangerous so if you are not confident on a ladder and at heights don’t attempt this one hire a pro. You should be looking for loose or missing shingles, deteriorated sealant, hail damage, exposed nails, or other signs of damage that could lead to a leak. If you find something out of place contact a roofing professional to get it repaired right. You should also remove any vegetation, or build-up on your roof. These can lead to premature failure of the roofing system and cost you big money sooner than it should.
- Seal the exterior walls/siding.
- One of the most common defects I write up on the exterior is holes in the siding that are not properly sealed. Depending on the siding this can lead to all sorts of issues from insect intrusion, to rot, to mold. Take a little time, walk around the exterior and seal up and penetrations or holes in the siding. Don’t forget to seal around doors and windows if necessary (not all siding types require this).
- Clean out dryer vents.
- Check your dryer vent for lint build-up and clean it out. This will help with your dryer efficiencies as well as reduce any fire risk from a clogged line.
- Clean your windows and screens.
- This will help you catch small issues like screen tears before they become bigger. It’s also nice to be able to see out a clean window.
- Have your Air Conditioner serviced
- This is one that you should have a professional do. They will have the right tools and knowledge to get your system serviced correctly. If you schedule this now, you won’t get caught in August when temps are in the triple digits and not having AC will make you miserable. Not having your AC system serviced annually will shorten its lifespan and end up costing you big in the long run.
- Wash and stain your fence.
- Keeping your wood fence clean and stained will greatly extend its life. No one wants to build a new fence or pay to have a new one installed. So take a weekend and get your fence cleaned and stained/sealed and it will last you a long long time. Neglect your fence and you will get to fork out a heck of a lot more money to have it replaced. This is a great job for a handyman or maybe the kid next door too.
- Perform yard maintenance.
- Get out there and get your grass ready for summer. Aerate, rake, mow, fertilize, and just get ahead of the game. There are tons of great blogs and youtube videos out there on what you can do to improve your yard but starting early will help a bunch.
- Trim back vegetation from the house exterior. You should have any vegetation touching or within one foot of the home. When vegetation touches the siding it can cause damage, decay, and invite pests into the home. Get all of your shrubs, bushes, and trees trimmed back away from your house in the spring to help prevent issues the rest of the year.
- Check your sprinkler system while you’re out there. It might a bit early to start watering as the spring showers will hopefully provide enough moisture for the next couple of months but you can get the system ready. Don’t wait until it is hot and dry to turn your sprinklers on to find out something is wrong and watch your grass die as you try to get it fixed.
- Check your sump pump if you have one.
- Sump pumps keep your crawlspace or basement from flooding. In some instances, they help remove water from around the foundation to prevent settlement issues. These are all very important and yet I rarely see sump pumps that have been serviced. I recommend having a plumber come to test and clean your sump pump in the spring to make sure it going to work properly. If you have a significant issue with water I also recommend having a backup unit on hand. I have seen far too many times during a wet spring when all the local stores run out of pumps and people are left with a big mess and big bills because their pump failed.
- Change your smoke detector batteries.
- If you don’t know the last time you changed your batteries go ahead and get them changed now and note it on the detector with a sticker. Then make sure to change them annually and test your detectors monthly. Some of the newer detectors have a sealed 10-year battery and don’t need to be changed every year. Make sure to check which kind you have.
All of these tasks can seem overwhelming but if you start now and tackle them one by one you will be ready to have a great summer enjoying your home. And don’t worry there will be a list of maintenance items for summer as well.

A common defect found in home electrical systems is grounds and neutrals terminated on the same bus bar in a sub panel.
Here is an explanation of why this can be dangerous. In short Laymen’s terms, if a fault occurs the breaker may not trip and metal components on that circuit (i.e. stove or fridge) could be come energized and electrocute someone who touches them. See below for a more through explanation.
Reference: NEC article 250.42.
We need to start by noting two things: (1) Current is always seeking a path back to its source, and (2) Current will take every available path it can find.
The function of the equipment grounding conductors (EGC), that ones that connect to the ground bar in the panel, is to carry fault current. If a fault occurs with a piece of equipment, such that a hot conductor comes into contact with the case or other external metal part, any person who touches that equipment is going to get a shock. The shock can be enough to kill, but the current will not be high enough to cause the breaker to trip.
However, with the EGC creating a path from the case back to the ground bar, then via the ground screw or bonding jumper to the neutral bar, the current in this path will be high enough to trip the breaker. This will terminate the event before the person can receive a fatal shock. That is why the ground and neutral buses are connected at the main service disconnecting means ? to complete the current path from the fault point back to the source. In this context, I am treating the main panel as the “source.” Once the current gets to that point, it has nowhere else go.
If you also connect the ground and neutral at a subpanel, then there will be two paths for current to flow back to the source during normal operation. Current will be flowing in the neutral most of the time (unless the loads running at the moment are perfectly balanced among the phases). But with the ground and neutral tied together both at the main panel and at the subpanel, the EGC will be in parallel with the neutral wire. Therefore, the EGC will carry current. This will cause the external metal parts of each and every component that has an EGC its to become energized. You could not safely touch anything in the facility.
Sewer Scopes for homes built between 1940-1975
- Mar, 25 2022
Was your home built between 1940 and 1975? If it was there is a very high likelihood that you have an Orangeburg sewer line. Why is this important you might ask? Orangeburg was a wood fibrous and tar material that was brought to prominence after World War 2 when metal was in short supply. This paper-like material had a life expectancy of 30-50 years which puts basically all of it well past its life expectancy.
When Orangeburg pipes begin to fail they can exhibit a crushing or squishing as the pipe becomes soft. This will lead to constriction of the pipe and eventual collapse. It can also exhibit what we call “eggs” where large bumps typically from rocks push into the side of the pipe as it weakens. These will all eventually lead to a complete failure of the line in the form of a collapse of blockage of the line. Repairs to these pipes can range from a few thousand to ten thousand dollars or more depending on the exact conditions. This is not something you want to be surprised by when buying a home. I strongly encourage anyone who is buying a home in this age range to add a sewer scope to your home inspection to make sure you aren’t surprised with a sewer line failure in the near future.
If you live in a home in this age range I can come out and provide you with a stand-alone sewer scope. This will let you know if you have this type of sewer line and what condition your line is in. This can prepare you for a repair before a complete failure and sewer backup that can add thousands of dollars to the repair and cleanup costs.
