Kenton County, Kentucky
Radon Mitigation in Covington, Kentucky
Covington sits in Kenton County, directly across the Ohio River from downtown Cincinnati. Kenton County is EPA Radon Zone 2 (predicted 2–4 pCi/L), but Zone 2 does not mean safe — Northern Kentucky test results frequently exceed the 4.0 pCi/L action level, so every home should be tested. If you own a home here, the only way to know your number is a test.
We're not a contractor. Ohio Valley Radon Mitigation is a referral service that matches you with a certified radon professional who works in Covington, then steps out of the way. The contractor gives you the quote and does the work.
Zone 2 geology
Why Covington basements pull radon in
Radon rises out of the soil and rock beneath your home and collects in the lowest lived-in level — usually a basement. Kenton County is EPA Radon Zone 2 (predicted 2–4 pCi/L), but Zone 2 does not mean safe — Northern Kentucky test results frequently exceed the 4.0 pCi/L action level, so every home should be tested.
Covington also sits at the confluence of the Ohio and Licking Rivers, and river-valley soils are part of the picture. The ground that holds and releases radon runs right under the neighborhoods on both riverbanks.
Older homes add to it. A full basement with cracked mortar, an open sump pit, and cold-joint gaps where the floor meets the wall gives the gas plenty of ways in — and that describes a large share of Covington's housing.
At or above 4.0 pCi/L, the EPA recommends fixing your home. Testing is the only way to learn your number. See the local radon data.
Covington housing stock
Older, dense urban housing over Zone 2 soil
Covington has one of the older, denser housing stocks in Northern Kentucky. Historic neighborhoods like Licking Riverside and MainStrasse Village are full of homes that predate 1940, many of them on full stone or block basements.
Those foundations were built long before radon was on anyone's radar. Decades of settling leave mortar joints, floor cracks, and unsealed penetrations — each one a path radon can follow up into the living space.
Rowhouses and closely spaced homes share the same valley soil, so a high reading on one block is a fair reason for neighbors to test too. Age and character are part of what makes these homes worth owning; they're also why a radon test belongs on the list.
Kentucky vs. Ohio rules
What "certified" means on the Kentucky side
Ohio requires a state ODH license to test or mitigate radon. Kentucky takes a different path — instead of mandating a state license, it recommends homeowners hire radon professionals certified through the national NRPP or NRSB programs.
That distinction matters when you're comparing quotes in Covington. You're not looking for an Ohio license number here; you're looking for current NRPP or NRSB certification, which shows the contractor has met the national training and proficiency standards.
The contractors we match you with hold those credentials. We confirm the certification is current before we connect you, so you can focus on the quote and the timeline instead of vetting paperwork. See how the matching works.
Buying or selling
Radon and the Covington real-estate market
Covington's historic homes move steadily, and a radon test shows up in a large share of those sales. When a buyer's inspection includes radon and the result lands above 4.0 pCi/L, the inspection-period clock starts.
We move quickly on those deadlines and match you with a certified contractor who can quote and schedule inside the window. On an older Covington home, a fast turnaround can keep a deal on track.
Sellers benefit too. A documented system and a passing post-mitigation test clears a common negotiating snag before it stalls your closing. See the real-estate radon page.

Covington questions
Radon questions from Covington homeowners
No. Unlike Ohio, Kentucky doesn't mandate a state radon license. It recommends hiring a professional certified through the national NRPP or NRSB programs instead. The contractors we match you with in Covington hold those certifications.
Yes. Older Covington homes on stone or block basements are mitigated all the time. A certified contractor tailors a sub-slab depressurization system to the foundation, sealing entry points and venting the gas above the roofline. See how a system works.
Most homes in the area land between $800 and $2,200 for a complete system, depending on foundation type and layout. Older basements with multiple entry points can sit toward the higher end. Our cost guide breaks it down.
