Radon Testing & Mitigation in Union
Union, Missouri is located in Franklin County, an EPA Radon Zone 1 area with high potential for elevated indoor radon levels. Radon is a naturally occurring radioactive gas that can enter homes through foundation cracks, slab joints, sump pits, crawlspaces, and soil-contact surfaces.
Union has a mix of established neighborhoods, mid-century ranch homes, and newer residential developments. Full basements are common throughout the area, making professional radon testing an important part of home ownership and real estate transactions.
Radon levels can vary significantly between neighboring homes. The only way to determine radon concentration is through professional testing. The EPA recommends mitigation when indoor levels measure at or above 4.0 pCi/L.
Testing is recommended every two years and during property sales.
