What to Expect
Ballwin, Missouri is located in St. Louis County, an EPA Radon Zone 1 area with high potential for elevated indoor radon levels. Radon is an invisible radioactive gas that forms naturally in soil and can enter homes through foundation openings.
Ballwin neighborhoods consist primarily of established subdivisions with full basement foundations. Many homes have finished lower levels, increasing the importance of accurate radon testing in occupied living spaces.
Because radon levels vary significantly between homes — even on the same street — professional testing is the only reliable method of measurement.
