Frequently asked questions
What radon level should I fix?
EPA recommends fixing your home if a test shows 4 pCi/L or more and suggests considering it between 2 and 4 pCi/L, since there is no known safe level.
Do I need a licensed contractor in Illinois?
Yes. Illinois requires radon mitigation work done for pay to be performed by an IEMA-licensed mitigation professional. You can verify licenses on IEMA's website.
How long does installation take?
Most single-family systems are installed in a day; the contractor should then re-test to confirm the level dropped.
Does sealing cracks fix radon?
EPA says sealing alone has not been shown to lower radon reliably; it's used together with a venting system.
Is this service free?
Yes. Requesting a quote is free and there's no obligation. You hire and pay the contractor directly if you choose to.
Do I have to disclose radon when selling?
The Illinois Radon Awareness Act requires sellers to disclose known radon test results and provide the state's radon pamphlet to buyers.
