What to Expect
Chesterfield, Missouri is located in St. Louis 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 openings and accumulate without visible warning signs.
Chesterfield properties commonly include full basement foundations, many with finished lower levels and high-value interior spaces. Because radon levels vary significantly from home to home — even within the same subdivision — professional testing is the only reliable method to determine exposure levels.
