Radon Testing in Addyston, OH — EPA-Aligned Results in 48 Hours

Addyston sits in Hamilton County along the Ohio River — a region the EPA classifies as Zone 1, the highest radon-risk designation in the country. Ohio averages 4.3 pCi/L indoors, above the EPA's 4.0 pCi/L action level, and limestone-rich soil under Hamilton County pushes many Addyston basements well past that threshold.

A licensed technician places the device in the lowest livable level of the home per EPA siting rules — typically a basement or first-floor bedroom. We brief the occupant on closed-house conditions: windows closed, HVAC running normally, no operating exhaust fans during the test window.

The CRM logs radon levels hourly. This gives us hour-by-hour data instead of a single averaged number — useful if a buyer's agent questions the result.

We retrieve the device, generate a report including average pCi/L, hourly graph, tamper data, and our license number (RC202), and email it the same day. Reports are accepted by every Ohio lender, title company, and Realtor we've ever worked with.

If your result is at or above 4.0 pCi/L, we can begin code-compliant radon mitigation within days. Our systems are permanent, sealed, and warrantied — designed to drop levels below 2.0 pCi/L in most homes.

Addyston is a small Hamilton County village along the Ohio River, west of Cincinnati and north of the Kentucky line. The geology under this stretch of the river valley — limestone bedrock, glacial till, and a high water table in spots — is exactly the soil profile that drives radon up through basement slabs and crawlspaces.

We test homes across Addyston and the surrounding communities: Cleves, North Bend, Sayler Park, Bridgetown, Cheviot, Delhi Township, and the Western Hills corridor. Older homes near US-50 and the river often have stone foundations and dirt crawlspaces — both high-risk configurations. Newer subdivisions further inland aren't immune either; modern sealed construction can actually trap radon at higher concentrations than a drafty 1940s home.

We also serve Addyston-area schools and commercial properties that fall under Ohio compliance requirements, and we work directly with local home inspectors who refer clients to us when their inspection reports trigger a radon callout.
