Anyone have radon testing done in their house? If so what is involved? Selling a house and one of the new requirements is to have a Radon Test. I am sure the pro will do a better test but Has anyone used those test kits from Home Depot or lowes? How accurate are they and what is involved in that? thanks

I used a radon test kit from one of the big box stores a couple of years ago. It required setting it somewhere appropriate (in my case, my basement), opening it up and leaving it there for a while. I seem to remember 3 or 4 days. Then I had to send it to the lab noted in the instructions along with a processing fee. ($30-$40). It took them about a month to get the results back to me. My radon levels were through the roof. I contacted a local radon mitigation firm who came out and ran their own test. Their test used a fancy piece of electronics and only took a few minutes. They confirmed that radon levels in my house were outrageous. The mitigation system they put in was surprisingly basic. They broke a hole in an appropriate place in my concrete floor and emptied out about 3 5-gallon buckets of gravel. The idea was to create a cavity for the radon to collect in as it rose out the ground. They inserted a piece of 4” PVC pipe into the cavity, then resealed the concrete. They ran the pipe out of my house and installed a blower on it (to suck the radon laden air out of the cavity) and ran the exhaust from the blower in more 4” PVC to up above my roof line. They came back about a week later and tested again and all was good with radon in my house. The price for the mitigation system was about $500—not bad IMHO. I believe the fancy electronic testers the pros use are quite a bit more accurate than the DIY type. I’m sure you can contact someone in your area to come out and test for a fee. The DIY kit is cheaper, and it’s probably accurate enough to help you decide about calling in the pros—but it does take longer to get results. Not sure if the real estate regs in your area will accept results from a DIY kit, so you may want to ask your realtor.

(Side note … my wife and I lived in that house for 13 years before we found out about the radon. We’re both still alive and neither of us has any cancer we’re aware of.)

Open up your house prior to testing (windows and doors) and let it air-out. You will pass with flying colors. The ‘cure’ for radon gas is exhausting it…
