Florence & Boone County, Kentucky
Radon Mitigation in Florence, Kentucky
If your Florence home tested high for radon, you don't have to figure out who's qualified on the Kentucky side of the river. We match you with a certified radon mitigation professional who works Boone County — and that professional handles the testing and the system, start to finish.
One thing up front so there's no confusion: Ohio Valley Radon Mitigation is a referral service, not a contractor. We connect you with our certified contractor partners and step out of the way. You pay them, not us.
Local radon context
Boone County is EPA Radon Zone 2
Florence sits in Boone County, Kentucky, just across the Ohio River from Cincinnati. Boone County is classified by the EPA as Radon Zone 2, where the predicted average indoor level is between 2 and 4 pCi/L. But a Zone 2 label does not mean safe: real-world Northern Kentucky test results frequently exceed the 4.0 pCi/L action level, and the river valley geology that drives radon on the Ohio side doesn't stop at the state line. Every home here is worth testing.
Here's where Kentucky differs from Ohio, and it's worth getting right. In Ohio, radon contractors must hold a mandatory license issued by the Ohio Department of Health (ODH). Kentucky does not require a state radon license. Instead, Kentucky recommends that homeowners hire professionals certified through a national credentialing body — the National Radon Proficiency Program (NRPP) or the National Radon Safety Board (NRSB).
So on the Kentucky side, the right question isn't "are you ODH-licensed?" — it's "are you NRPP- or NRSB-certified?" That national certification is the standard we match Florence homeowners against. See how radon testing works →
Kentucky recommends NRPP- or NRSB-certified radon professionals rather than mandating a state license — a real difference from Ohio's required ODH credential. Your Florence home still needs its own test.
Florence growth & housing
Why Florence homes are worth testing
Florence is the largest city in Boone County, and Boone County has been one of the fastest-growing counties in Kentucky for years. New subdivisions keep filling in around the Mall Road and Houston Road corridors, and the housing stock runs from mid-century ranches to homes finished last year.
That range matters for radon. Older Florence homes have had decades for foundations to settle and crack, opening more paths for gas to seep in. But newer construction isn't safe by default — many of the newer builds here sit on full basements, and a basement is exactly where radon collects.
If your family uses that lower level as a rec room, an office, or a bedroom, you're spending real hours in the part of your home where radon runs highest. That holds whether the house dates to 1965 or 2024.
No two homes vent the same way, which is why a certified contractor sizes the system to your specific foundation. See what a mitigation system includes →
Buying or selling
Radon and the Florence real-estate market
Boone County runs one of the busiest real-estate markets in Northern Kentucky, and Florence is a big part of it. Homes move quickly, and radon testing now shows up in most lender-backed transactions on this side of the river.
If you're under contract, the calendar is the pressure. Inspection periods are short, and a high reading can hold up a closing until a system is installed. Our certified contractor partners prioritize real-estate deadlines and can often test and quote fast.
Selling? A recent test — and, if it comes back high, an installed system — is one less thing for a buyer to negotiate. See how radon fits a real-estate deal →
Many Cincinnati radon companies barely cover the Kentucky side.
Plenty of firms across the river don't create Northern Kentucky content or actively serve Boone County. That gap is exactly why we cover both sides of the Ohio River.

Florence radon questions
Local questions homeowners ask
No. Unlike Ohio, which mandates an ODH license, Kentucky does not require a state radon license. Kentucky instead recommends that homeowners hire professionals certified through the NRPP or NRSB. We match Florence homeowners with certified contractors so you get that national standard.
Boone County is EPA Radon Zone 2 (predicted 2–4 pCi/L), and Florence sits in it. A Zone 2 label does not mean safe — Northern Kentucky test results frequently exceed the 4.0 pCi/L action level, so every home is worth testing. The only way to know your level is a test.
Yes. A newer Florence build often comes with a full basement, which is where radon concentrates. New construction doesn't rule out elevated levels, so a test is still the right first step.
No. We're a referral service. We match you with an independently certified radon professional who covers Boone County, and that contractor performs all testing and mitigation. See how it works.
