Radon Risk in Milwaukee
Milwaukee and Milwaukee County sit in EPA Zone 1, the highest radon-risk classification. The Wisconsin Department of Health Services reports that 5 to 10% of Wisconsin homes have radon levels above 4 pCi/L on the first floor — and far more in basements, with southeastern Wisconsin among the higher-risk regions. The area's glacial deposits over dolomite bedrock release radon that collects in the deep basements common to Milwaukee homes. The EPA and WI DHS recommend testing every home.
Why Radon Testing & Mitigation Matter in Milwaukee
Deep Basements
Milwaukee's classic brick bungalows, duplexes, and Polish flats almost all sit over deep full basements in direct contact with radon-bearing soil — the primary driver of elevated readings.
Geology & Climate
Southeastern Wisconsin's glacial till and dolomite bedrock release radon naturally. Long, cold winters keep homes sealed for months, maximizing radon buildup indoors.
Health Risk
Radon is the second leading cause of lung cancer after smoking. The EPA action level of 4 pCi/L is a safety threshold — any level above it warrants mitigation.
Affordable Mitigation
Most Milwaukee-area homes can be mitigated in a single day with sub-slab depressurization. Costs typically run $1,200–$2,500 for a standard system.
Wisconsin uses national certification (rather than a state license) for radon professionals. All contractors shown are NRPP or NRSB certified. For local guidance and a list of regional radon information centers, visit Wisconsin DHS Radon Program.
