FAQ: Radon Mitigation in Ohio

Does Ohio require radon disclosure?

Yes. Ohio's residential property disclosure form includes a radon disclosure section. Sellers must disclose known test results.

How much does radon mitigation cost in Ohio?

Most homeowners in Ohio see mitigation quotes in the low-thousands, but the final cost depends on foundation type, fan location, and pipe routing complexity. A cost calculator can help you benchmark estimates before requesting bids.

Do I need radon testing in Ohio before hiring a contractor?

Yes. A valid short-term or long-term test is the fastest way to confirm if mitigation is needed and to scope the right system design.
