Radon Testing & Mitigation in Dayton
The Miami Valley region — including Montgomery, Greene, and Clark counties — consistently records some of the highest residential radon levels in all of Ohio. The area’s unique limestone and karst geology creates natural pathways for radon to migrate into homes. Our licensed technicians have protected thousands of Dayton-area families from this hidden threat.

Why Dayton Homeowners Need to Know
Approximately 45% of Dayton-area homes test at or above 4.0 pCi/L — among the highest rates in the state. Apartment communities on HUD or agency financing: see multifamily radon testing. Centerville, Beavercreek, Kettering, and Miamisburg all show particularly frequent elevated readings driven by the Miami Valley’s distinctive geology.
The Miami Valley sits above Silurian Niagaran dolomite — naturally high in uranium and radium. As these minerals decay, radon is continuously generated and migrates upward through the valley’s permeable glacial gravel deposits into building foundations.
Radon is invisible, odorless, and tasteless. The only way to know if your family is at risk is to test. It takes 48 hours and costs less than a tank of gas.
WHAT THE EPA SAYS ABOUT OHIO
- Ohio is EPA Zone 1 — the highest radon risk designation.
- The EPA action level is 4.0 pCi/L — above this, mitigate.
- Radon is the #1 cause of lung cancer in non-smokers.
- ~21,000 Americans die from radon-induced lung cancer each year.
- No color, smell, or taste — testing is the only detection method.

“During our home purchase in Centerville, the radon test came back at 9.1 pCi/L — more than double the EPA limit. Buckeye State Radon accommodated our closing timeline and had the system installed in one day. Professional and genuinely caring team.”
James & Linda K.Centerville, OH“I’m a physician and I know firsthand how serious radon exposure is. Buckeye State Radon tested our Beavercreek home and found levels of 7.3 pCi/L. Their mitigation system brought us down to 0.6. I recommend them to every patient who asks.”
Dr. Robert A.Beavercreek, OH“We had two young children and were terrified when we found out our radon level was 11 pCi/L. The team arrived the very next day, explained everything clearly, and the system was running by that afternoon. They truly care.”

Why does the Dayton area have such high radon levels?
The Miami Valley’s geology is particularly radon-productive. The region sits above Silurian-age dolomite and limestone formations that are naturally high in uranium and radium — the source elements for radon gas. The glacial gravel and till deposits that blanket the bedrock also serve as highly permeable pathways that efficiently conduct radon gas upward toward building foundations. This combination makes the Dayton area one of the highest-risk radon regions in the entire country.
Are certain Dayton neighborhoods at higher risk than others?
Radon levels can vary significantly even on the same street, so every home must be individually tested. However, our experience serving Dayton-area homes shows elevated readings are especially frequent in Centerville, Beavercreek, Kettering, and Miamisburg — all built on the valley floor where glacial deposits are thickest. Homes in higher-elevation areas like parts of Springboro may see slightly lower levels, but no neighborhood is immune.
I rent my home in Dayton — can I still get my unit tested?
Yes. While landlords in Ohio are not legally required to test for radon, tenants have the right to request testing. We can work with tenants and landlords alike. If you’re a renter concerned about radon, we recommend discussing testing with your landlord first — the cost is modest and the health protection is significant for everyone in the building.
Does radon affect Wright-Patterson AFB housing and nearby communities?
The Fairborn and Beavercreek communities surrounding WPAFB are built on the same high-radon geology as the rest of Greene County. Military families living in community housing near the base are well-advised to test — radon is color-blind and rank-blind, and the homes in these communities can test quite high.
How much does radon mitigation cost in the Dayton area?
Most residential mitigation systems in the Dayton area range from $800–$1,500 depending on your home’s foundation type, size, and the complexity of the system needed. We provide a free estimate before any work begins. We also offer radon testing starting at $125–$175 for a 48-hour continuous monitor test.
Do you serve communities in Clark County and Springfield?
Yes. We serve the entire Clark County area including Springfield, New Carlisle, Enon, and South Charleston. Clark County also falls within Ohio’s EPA Zone 1 designation and sees elevated radon levels consistent with the broader Miami Valley region.
