Its a charcoal type canister, if a reputable lab is testing, I can't see why it would be any different. That being said, $110 seems high for a radon test, but of course this could be regional. Most inspectors in my area include this in part of the inspection and generally charge in the $600 range for a complete inspection including, radon. Call around, there really is nothing to a radon test.

The radon inspector is just going to send it to a lab and pocket the difference. Unless there is something really complex about the situation, you should be able to do this yourself just as reliably.

I am the buyer. If we find there is radon we will install an exhaust fan.

If not, no need.

We moved into our house a year ago. Neighborhood talk was that radon was sometimes an issue in our area. We bought a kit and did it ourselves after our remodeling was complete. The result was low enough that we aren't at all worried. If the result had been marginal or high, we would have hired a company to do a second test prior to remediation.

Yes, that is what I assumed. While we can follow instructions on a radon test kit, we don't know how to do DIY on home repairs, so no risk on that count.

@nickel_kg - When you moved into your house 1 year ago did you have a radon test done? If so, may I ask why you tested again after remodeling?

Lotus, radon is prevalent in my area. I sell real estate full time. Rarely, does anyone not get a radon test. When I our purchased my own home, there was a radon system. I tested anyway. Turned out the previous owner did not install the system on the lowest possible level so the lowest level which is where radon comes in was a 10 with a system! Of course we had it corrected. A radon system is not an expensive fix. The most expensive system I have ever seen in all my years of real estate was $1500 and this was for a humongous basement. You are talking a difference of $50 between doing it yourself or having someone do it. IMHO it isn't worth all this stress. Buying a house is an expensive endeavor. $50 is a small price to just get it done

Good point, @linda117117.

If a house is found to have radon then in your experience do most buyers move on to look for a different house, or get it fixed?

It's so common in some areas, and as Linda said, the fix isn't outrageous, that when I sold my late mother's home in 2014, we had the system put in. I think a smart buyer will request a test for it, and a smart seller will pay the relatively little to have it remediated. I don't think any informed buyer would walk away, especially since in some areas, all homes will show it on a test.

I agree with everything My3dogs said. The important thing to be aware of in a real estate transaction situation is that "short-term" radon tests can take anywhere from 2 to 90 days depending on the test method technology, plus whatever time it takes for the test lab to receive the test kit, analyze it, and send you the results. If time is.of the essence, be aware of those factors. Longer times can give better average results as conditions in a house can vary from day-to-day, but shorter times can also be adequate. Here is a useful EPA guidebook on radon in homes: Radon

lots, in my area, its not a deal killer at all. Its an easy, inexpensive fix.

Two of my neighborhood homes (of which I'm aware) needed Radon remediation. Approximately $2K for each. Two stories with basement, MD suburbs of DC.
