What to Expect
Radon mitigation systems in Florissant rely on continuous fan operation to maintain negative pressure beneath the foundation. If a radon fan fails, radon levels can rise.
Because St. Louis County is classified as EPA Zone 1, maintaining proper mitigation system performance is essential.
