Minnesota
More than 2 in 5 Minnesota homes have radon levels that pose a significant health risk, and the state average is more than three times the U.S. level.1
Licensing
Minnesota requires anyone doing radon mitigation to be licensed by MDH. Ask for the installer's individual license number.2
Home sales
Under the Minnesota Radon Awareness Act, sellers must disclose what they know about radon in writing before a purchase agreement is signed.3
Which guide do you need?
If you haven't tested, start with the testing guide. If you have a result at or above 4 pCi/L, the mitigation guide explains how systems work and what a licensed installer should do, and the cost guide shows what Twin Cities homeowners can expect to pay.
