Certified Radon Mitigators
in Milwaukee, Wisconsin

Milwaukee and Milwaukee County sit on Silurian dolomite bedrock overlain by glacial till and lake sediments, a combination that produces moderate to elevated radon across the metro area. Wisconsin's northern and central counties run higher than the Milwaukee metro, but the city's older housing stock — particularly brick colonials and ranches with full basements in Wauwatosa, Shorewood, and Bay View — tests above the action level with regularity. Wisconsin requires state certification for radon contractors, providing a clear standard for consumers to verify. Milwaukee's competitive contractor market keeps pricing at or below Midwest averages.
