Should I re-test for radon after buying a Faribault home, even if it tested fine before?

It's a good idea. Radon levels aren't perfectly static; they vary with the seasons, the weather, how the house is operated, and changes to the structure. A test that came back below the action level during a summer sale, with windows occasionally open, might read differently in the dead of a Faribault winter when the house is sealed up tight and soil gas concentrates indoors. The EPA recommends testing every couple of years and after any significant renovation, foundation work, or change to your heating and ventilation system, all of which can alter how radon enters and accumulates. Given Rice County's elevated regional radon levels, periodic re-testing is cheap insurance for your family's health. If you install a basement finish, a new sump system, or do foundation sealing, re-test afterward. And if a home already has a mitigation system, confirm it's still performing with a fresh test. Radon is a long-term exposure risk, so ongoing awareness pays off. To schedule a radon test for your Faribault home, call us or build a free instant quote online.
