Radon & Your Basement in Potter County

Potter County is in EPA Zone 2. Basements in this area may have radon levels that exceed the EPA action level, even though the county average is moderate. Many homes in Zone 2 areas still require mitigation.

Radon concentrations are typically highest in the lowest level of a home. However, radon does not stay confined to the basement — it migrates to upper floors through stairways, HVAC ducts, and gaps in flooring. Even if your basement is unfinished or rarely used, elevated radon there can affect the air quality on your main living floors. Always test on the lowest livable level.
