The short version
What radon is, and why Cincinnati keeps coming up
Radon is a radioactive gas that seeps up from the soil and rock beneath your home. You can't see it or smell it, and the glacial till and Ohio River valley geology under Greater Cincinnati produce more of it than most of the country.
The gas enters through foundation cracks, sump pits, and slab penetrations, then collects in the lowest lived-in level — usually a basement. Over years, breathing elevated levels raises lung-cancer risk. The EPA sets a clear line where it recommends you act.
Testing is the only way to know your number. If it's high, a mitigation system brings it back down — reliably, and usually for less than people expect. See the health risks or how a mitigation system works.

Why Greater Cincinnati has a radon problem
The whole region falls in EPA Radon Zone 1, the category with the highest predicted indoor levels. That designation isn't marketing — it comes from soil, bedrock, and decades of test data.
Ohio River valley geology is the reason. Glacial till and fractured limestone hold and release uranium's decay products, and radon rides that path straight into basements. Older neighborhoods add to it — a large share of the housing stock predates 1940, with foundations that give the gas plenty of ways in.
Ohio's real-estate disclosure form also puts radon in front of every buyer and seller, which is why so many Cincinnati transactions include a test. See the county-by-county radon data →
Radon-system searches in Cincinnati are up 70% in the past year.
More homeowners are researching the physical system — the pipe, the fan, the exhaust — not just the service.

Common questions
Radon questions Cincinnati homeowners ask
No. Ohio Valley Radon Mitigation is a referral service. We match you with an independently licensed, Ohio ODH-credentialed radon contractor who covers your area, and that contractor performs all testing and mitigation.
Most Greater Cincinnati homes land between $800 and $2,200 for a complete mitigation system, depending on foundation type and layout. Our cost guide breaks it down line by line.
The EPA recommends fixing your home at or above 4.0 pCi/L. Many homeowners also mitigate in the 2–4 range, since there's no truly "safe" level. A good system usually gets a home below 2.0.
Same-week service is common across our contractor network, and real-estate deadlines get prioritized. Tell us your timeline when you reach out.
