Radon Testing & Mitigation in De Soto
De Soto, Missouri is located in Jefferson County, an EPA Radon Zone 1 area with high potential for elevated indoor radon levels. Radon gas forms naturally in soil and rock and can enter homes through basement slabs, crawlspaces, sump pits, expansion joints, and foundation penetrations.
Residential properties in De Soto range from established subdivision homes to rural-edge houses on larger lots. Full basement foundations are common, although some homes include crawlspace construction depending on terrain and grading. Rolling topography in parts of the area may influence soil gas movement beneath structures.
Because radon levels vary significantly from one property to the next, professional testing is the only reliable way to determine indoor concentration. Testing is recommended every two years and during real-estate transactions. If radon levels measure at or above 4.0 pCi/L, mitigation may be recommended.
