At least a few times a week I ask a client if they want a Radon test performed on their new house. Most give a sharp “yes” without hesitation. Some folks, however, don’t know what to say, or may be confused from the all the different opinions they have gotten from their realtor, dad, cousin, neighbor, etc… Let’s see if we can clear things up a bit.
If you are buying a home in Louisville (all of KY really) you should have it tested for Radon Gas. Every home should be tested for Radon gas. No exceptions; especially in homes that already have a Radon mitigation system installed in the home. We’ll get into the “why?” of that in more detail later. There are only two types of houses that don’t have some form of Radon Gas around here. Houseboats and tree houses. Unless your house falls in one of those categories, you need to get it tested. Here is an EPA map of Jefferson County KY. Notice how nearly every part of the county is in the red; Zone-1.
What is Radon Gas?
Radon is an odorless, colorless, radioactive gas that comes from the earth. It forms naturally from the decay of radioactive elements in the ground, such as uranium. Some locations have much higher levels of these elements than others. This is why some areas have high levels of Radon gas, and others only have trace amounts. We just happen to drawn the short straw here in Louisville and have some of the highest amounts found in the U.S.
Radon is found both indoor and outdoors. Outdoor levels are typically very low, while the measurements in indoor buildings can range from very low to extremely high. As the Radon breaks down in the ground, it seeps in through the cracks and holes in the foundation of your home. If enough Radon gas makes it through, the house will test high for Radon.
How to test for Radon in your home.
There are several different ways to test for Radon, but the easiest way is to have a CRM (continuous radon monitor) placed in the home for several days. EPA (Environmental Protection Agency) testing protocol says the machine should be left undisturbed in the home for a minimum of 48 hours, up to 7 days. Placement of the CRM is always on the “lowest potential living space.” This means if you have an unfinished basement, but may one day finish it out, you run the test from that area.
If the home has a crawlspace or concrete slab (since no one will ever live under the house) the CRM monitor is placed as close to the center of the house as possible on the first floor. You also want to keep the machine away from exterior doors and windows (that is to simply keep as much fresh air away from it as possible, which can dilute the radon gas and affect the test). Once the machine is in place and running the test, it will take an air sample once an hour, every hour, until the test has been stopped. Those numbers are then averaged to give you your test results in picocuries per liter or pCi/L.
The house doesn’t have a basement, do I really need a Radon test?
Yes, you do. A home is not required to have a basement to have high levels of Radon gas. Somehow, a nasty lie got started years ago that a home that was built on a concrete slab, or a crawlspace “won’t have Radon, only houses with basement do.” This is 100% completely false. Some of the highest numbers I’ve ever seen came from homes that were built on slabs and crawlspaces. I’ve also heard it said that walkout basements don’t have Radon. Again, this is simply not true. There is no building style that is Radon proof, or Radon resistant. All homes have the potential for elevated Radon gas, so all homes need to be tested.
The house already has a mitigation system installed, why waste the money on a test?
I hear this all the time, and the answer is quite simple. There are lots of systems that don’t work properly. More than you would think. Oh, they’re in place, and the fan is running, yet the Radon levels are still elevated when I test the home. That is because anyone with a truck, a cheap fan, and some PVC pipe can call themselves a Radon mitigation company. There are no laws or rules currently enforced in Kentucky for Radon mitigators; it’s the “Wild West,” and it shows in the quality of work that I see.
Look at it like this. If a home has a mitigation system, that means the levels were once high enough to warrant the install to begin with. It is in your best interest to double check to see that the system is working properly, and is actually lowering the Radon gas levels. Over the course of the past year, I tracked my data on testing Radon in houses where Mitigation systems were already installed. My results: One in every five systems were not working properly. In several homes, the mitigation fans didn’t work at all.
Test completed. Now what? EPA vs WHO
Now that you have your numbers, let us talk about what all this means, and what you need to do next.
There are two sources that folks look to for guidance when it comes to Radon gas and their home. The EPA (Environmental Protection Agency) and the WHO (World Health Organization). The EPA says that homes with 4.0pCi/L or more should have a Radon mitigation system installed in the home. However, in 2009 the WHO released a study that stated they are lowering their recommended action level to 2.7pCi/L. Most people in the real estate world won’t tell you about the newer WHO study though. Sometimes its just plain ignorance (you’d be shocked at the amount of people I run into every week that have never heard of the WHO), but other times it’s just not convenient to the transaction at hand. You see, lots of homes fall in between the 2.7 and 3.9 levels, and when home buyers want the sellers to foot the bill for a Radon mitigation system, well, the higher the action level numbers are, the better…. for the transaction. So who’s right? Which organization do you listen to; who do you go by? I don’t know. In fact, I don’t know if there is a right answer.
In my mind, it is simply not worth the risk. Radon mitigation systems are not extremely difficult, or expensive to install.
Mitigating the problem-
So you’ve had your Radon test completed, and the home came back elevated. It’s time to get a Radon mitigation system installed. Radon mitigation systems are simple creatures by nature, but not just any jack-leg can install them (although they try). Just like choosing your home inspector, you need to be picky and smart about who you choose to install your Radon mitigation system. I’ll get into mitigation systems, and what problems can come up from them in a later post.
Another year older, one or two more gray hairs found, and a stack of pictures to choose from. It’s hard to whittle it down to just a handful, but I selected the top 10 problems found during home inspections this year.
A Cold Fireplace – This is a picture from a one year old home. The owners paid extra to have a vented gas fireplace insert installed. What they didn’t realize is they would be paying extra on their heat bill forever because of it. You can see through the eye of my thermal imaging camera that the lower section of the insert was not insulated or air sealed. It’s constantly letting cold in air. The room temp was 68, the outside air was 17. This is why thermal imaging home inspections are awesome. It put visual reasoning to a problem you can feel. This problem is fixable, but it would requiring removing the mantle and fireplace to air seal/insulate the back wall.
Structural Window – Ok, there is no such thing, but this window in this custom garage is acting as one. The owners of this two month old custom built garage called me when they started to have trouble with water leaking in. I came out to find what the water problem was. I did, and found this beauty as well. Whenever we have masonry spanning the top of a window or door or opening, there should be a piece of steel installed above the window, called a lintel. This L shaped support is what holds everything up in the air. These concrete blocks are resting on the window frame only. No steel. Only water leakage.
Flooded Crawlspace – There is not much I won’t do for my clients. I have been bitten and stung. I have crawled through dead animals, piles of poop, puddles of pee, and everything you can imagine to get the low down on a house. But I drew the line with this crawlspace. I took one look in there with the exposed and flooded electrical lines and “noped it.” The buyer just laughed and said “I don’t blame you.”
Rotting Creatures – In keeping with the creepy, nasty crawlspace theme; one day I turned the corner and stumbled across this guy. I think it used to be a possum at one time. It may not seem too bad now, but imagine yourself in a dark, wet crawlspace. You’re crawling on your belly, turn the corner and find this dude 6 inches from your face. It’s a bit startling. Oh, and wet, decomposing hair smelled great!
See Through Drain – Ever wondered what your bathroom sink drain looks like? Yeah, me neither. But if by some chance you do….wonder no more. This thing is flat out gross. It was almost like a lava lamp for hair and dead skin cells.
So there is the first five. It’s tough picking a top ten with thousands of pictures to choose from for sure, but you can see part two here- ABI Home Inspection – Best of 2014 Part 2
I was recently invited to be a guest speaker on the River City Real Estate Radio Show. Try saying that 10 times fast!) My friend Sam George, a fabulous Realtor in Louisville was with me as well. We were there to talk about home inspections, and the most common questions people have about what I do, and how the process works.
Of course, the first thing you think of when being on the radio is how you hate the sound of your own voice. I’m no exception. Do I really sound like that? Yeah, I’m afraid so. Hate aside, it was a fun process. I would do it again tomorrow. Brady is doing a great thing in trying to get good info out to people. I highly suggest you tune in. You can hear the show every Saturday morning at 11 on 1080am Talk Radio. As always, if you have any question about what I do, and how I can help you, feel free to give me a shout 502.938.5190, or email here. You can listen to the whole episode below.

I made the decision to start ABI Home Services after spending nearly a decade in the home remodeling field, working my way from helper to job foreman. That time has afforded me the ‘hands-on’ experience that a home inspector needs to really understand how a home should be constructed and maintained. Although classroom time and education are important factors in becoming a home inspector, I believe that nothing can replace the actual experience of doing the work yourself.
I have chosen to take the road less traveled by many home inspectors, and invest in cutting-edge technology for ABI Home Services. I carry a vast array of specialized equipment to assist in our work. Without this equipment, you simply cannot get a thorough inspection. This sizable investment has given us not only the ability to give you, our client, the home inspection you deserve, but allows us to convey our findings in a understandable way.
I realize that you have a multitude of choices when it comes to getting your home inspection, and I thank you for taking the time to consider ABI. If you have any questions for me, or about ABI Home Services, please feel free to give me call. I will be more than happy to answer all of your questions.

Not only do you need a great home inspector, you need one who produces a great home inspection report. Luckily, you found me.
Here are some examples of what your home inspection report will look like with Ben. Keep in mind however, that every report is unique and individualized to your specific home. A typical home inspection report can range anywhere from 30 pages up to 80 or more, depending on the age and condition of the home.
Many home inspection companies boast about “on-site” delivered reports. This is a surefire way for mistakes to be made. After I complete my inspection of the home I take my pictures and notes back to the office to prepare your report.
This is a critical part of the home inspection process. Mistakes can easily be made by trying to present you with a report “on-site.” My report process can take 3-5 hours to complete. I do not want to waste your day waiting for us to complete your report on-site. Once completed, you will be emailed a PDF version of your home inspection, complete with color coded text and photos.
I do NOT rush my home inspections. At most we schedule one home inspection per day. If your home needs more attention (large, old, and/or in “fixer-upper” condition) I’ll dedicate as much time as it takes, up to a day or more, for your inspection.
My home inspections and reports are completed and prepared by the ASHI Standards of Practice. You may download a copy of these standards here – ASHI SOP. This will give you a better idea of what you can expect from your home inspection. As always, you may give me a call if you have any questions about the process.

You get what you pay for. Here is an example of what a cheap $300.00 inspection report looks like from an local inspector here in Louisville. Are you comparing apples to apples when searching for a home inspector? Most people only do this kind of thing a couple times in their lives and don’t know any better. Don’t fall into the cheap guy price trap. You’ll only drown in problems down the road.
