Michigan includes EPA Zone 1 counties, so radon mitigation in Detroit should be treated as a core indoor-air priority. 1 local contractor is currently listed, so broader metro comparisons may help with pricing and availability. Based on EPA county-level mapping, Michigan includes Zone 1 areas, which indicates high predicted indoor radon potential. State context: Michigan's glacial soils create ideal conditions for radon. The Ann Arbor-Detroit corridor and Grand Rapids metro both have significant radon issues.
We track 1 local contractor. The strongest service coverage is 100% testing and measurement.

Compare your estimate with the cost calculatorPrimary state-level EPA reference: Zone 1. Most of the Lower Peninsula is Zone 1, particularly the southeastern and central regions. The Upper Peninsula is mostly Zone 2.
EPA zone maps are county-level screening tools. Home-level testing is still required to confirm risk.
Michigan is generally mapped as higher-potential radon territory (Zone 1), so annual-to-biannual testing is common after mitigation or major foundation changes. For seasonal timing, closed-house winter testing usually captures worst-case indoor buildup. For real-estate transactions, run a short-term test during due diligence, then confirm with follow-up testing if results are near or above 4.0 pCi/L.
