If you're dealing with radon in the St. Louis area, mitigation usually involves sealing cracks in the foundation and installing a vent pipe that pulls gas from beneath the house. The clay soil common to this region can make radon levels unpredictable, so testing during the dry season gives a more accurate reading. Many older homes here were built before radon awareness became common, so retrofits may require a contractor familiar with the area's unique geology and crawl space designs.
