FAQ

Does RadonFixers install radon systems?

No. RadonFixers does not perform installs, testing, or repairs. We connect homeowners with independent, state-licensed contractors, and each request goes to at most 3 of them.

Where do your contractor listings come from?

From official state licensing lists (Pennsylvania DEP, Minnesota MDH, Illinois IEMA). Each state page links to its source and shows the date we copied it.

Is it free for homeowners?

Yes. In the future we may be paid by contractors for referrals, and we will disclose that on the site.
