Testing for Radon Before Installing a Floor Over Dirt Basement

  • Transcript

    LESLIE: Amy in Iowa is on the line with a question about a dirt basement. Tell us what’s going on.

    AMY: Hi. I recently have purchased an old farmhouse and in the basement, it has a dirt floor. And I was wondering if I should lay concrete on it or if I can lay that thick plastic and put gravel on top to help with the radon and try to keep some of the heat in there.

    TOM: Do you know that you have a radon problem?

    AMY: Well, I don’t. They talk about it in Iowa being an issue. And with it being a dirt floor, I didn’t know if that was something I should have tested first or go ahead and just leave the plastic and the rock and be …

    TOM: I would definitely test because you don’t know what you’re dealing with. You may have to put stone down and then put a concrete floor and then do a ventilation system where you draw the gas up off from underneath the concrete. So, the first thing you have to do is test.

    So, do it yourself or hire somebody. And do it right. The testing has to be done under closed building conditions with all the windows and doors closed, except for normal exit and entry. And find out what you’re dealing with and then you can take the appropriate steps after that. But don’t just put it down thinking that if you have a radon problem, it’s going to solve it. Because frankly, it may not.

    AMY: OK. Alright. Well, thank you so much for your help.

    TOM: You’re welcome. Good luck with that project. Thanks so much for calling us at 888-MONEY-PIT.
