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