Northern Kentucky
Radon Mitigation in Campbell County, Kentucky
Campbell County is the easternmost of the three Northern Kentucky counties in our service area, sitting directly across the Ohio River from Cincinnati. The EPA places Campbell County in 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. The only way to know your number is to test.
We're not a contractor. Ohio Valley Radon Mitigation is a referral service that matches you with a certified radon professional who covers Campbell County, then steps out of the way. The contractor gives you the quote and does the work.
Zone 2 geology
Why Campbell County homes 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. Campbell 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.
The county runs along the Ohio River, and the same river-valley soils and fractured bedrock that drive radon on the Cincinnati side don't stop at the water. The ground that holds and releases the gas runs right under the neighborhoods on the Kentucky bank.
A Zone 2 label is a prediction of the average, not a ceiling. Individual homes across the county have tested well above 4.0 pCi/L, which is exactly why testing matters more than the map.
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.
Campbell County housing
Two kinds of housing, one radon risk
Campbell County's housing is bifurcated, and both halves carry radon risk for different reasons. Along the river, the older cities hold a dense urban stock; to the south, the suburbs are still filling in with newer homes.
Newport, the county seat and largest city at roughly 14,500 people, sits directly across from Cincinnati. Much of its housing predates 1940 — closely spaced homes on full basements, with the settled mortar joints, floor cracks, and unsealed penetrations that give radon easy paths inside. The neighboring river cities of Bellevue and Dayton, Kentucky share that same older, dense character.
South of the river, Alexandria is a growing suburban community with newer housing, but basements are common there and a Zone 2 label doesn't spare a new home. Cold Spring, between Newport and Alexandria, is another growing suburb built largely on basement foundations. Newer construction can still draw radon up through the slab, sump, and utility penetrations — which is why radon testing is increasingly part of the home inspection process in the suburbs as much as in the river cities.
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 — the Kentucky Board of Radon Safety (KBRS) registers radon contractors, and NRPP certification is recommended rather than a mandatory state license.
That distinction matters when you're comparing quotes in Campbell County. You're not looking for an Ohio license number here; you're looking for a contractor registered with KBRS who holds current NRPP certification, which shows they've met the national training and proficiency standards. You can read the state's rules at kbrs.ky.gov.
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.
Crossing the river
Filling a real Campbell County gap
Many Cincinnati-area radon contractors don't cross the river to Campbell County. It's a consistent gap — homeowners in Newport, Alexandria, and Cold Spring call around and find that the closest crews stay on the Ohio side.
This service exists to close that gap. We match Campbell County homeowners with certified contractors who actually cover the Kentucky side of the river, so you're not left chasing quotes that never come.
Whether your home is a century-old Newport river house or a newer build in Alexandria, we connect you with a professional who works your area and can schedule the visit.
Buying or selling
Radon and the Campbell County real-estate market
Radon testing is increasingly part of the home inspection process across Campbell County, in both the river cities and the growing southern suburbs. 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. A fast turnaround can keep a deal on track whether the home is in Newport or Alexandria.
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.

Campbell County questions
Radon questions from Campbell County homeowners
Yes. Zone 2 predicts a 2–4 pCi/L average, but that's a prediction, not a guarantee. Northern Kentucky test results frequently exceed the 4.0 pCi/L action level, so every home should be tested regardless of the zone map.
Not the way Ohio does. Kentucky's Board of Radon Safety (KBRS) registers radon contractors, and NRPP certification is recommended rather than a mandatory state license. The contractors we match you with in Campbell County hold those credentials.
Yes. Newer suburban homes in Alexandria and Cold Spring are usually built on basements, and radon can still enter through the slab, sump, and utility penetrations. Age doesn't rule out a high reading — testing is the only way to know.
Yes. Older Newport homes on full 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. Our cost guide breaks it down.
