About Radon Mitigation Directory

Radon Mitigation Directory helps homeowners find certified radon mitigation contractors — the professionals who install the fix when a radon test comes back high. We focus on mitigation because that's the urgent, high-value job, especially during a home sale.

Contractor listings are built from the AARST / NRPP National Radon Proficiency Program registry and cross-checked against state certification lists. We link each pro's credential so you can verify it independently. We are an independent directory, not affiliated with the EPA, AARST, or any state agency.
