Certified Radon Mitigators
in Detroit, Michigan

Detroit and Wayne County sit on thick glacial deposits over Devonian limestone and shale, with radon levels that are moderate to elevated across the metro area. Michigan's average indoor level is around 3.3 pCi/L, but individual homes in older Detroit suburbs — Dearborn, Livonia, Westland, and the Grosse Pointes — frequently test above the action level. Detroit's large housing stock includes many mid-century brick ranches and two-stories with full basements that are well-suited to standard mitigation. Michigan requires state certification for radon contractors.
