Radon testing for Columbus homes: what Ohio says
Ohio licenses radon testers (Ohio Administrative Code) and bars unlicensed people from giving professional radon testing advice. Homeowners can test their own homes. The Ohio Department of Health has offered free test kits to residents (Dispatch report). Call us if you want a pro to run it and explain it.

I would definitely recommend Columbus Radon Mitigation to anyone concerned about radon in their home. They were professional from the first phone call through installation. The team explained the system, answered our questions, and made sure we understood the importance of follow-up testing. A great experience overall!
