Radon Risk in Minneapolis & Hennepin County
Minnesota consistently ranks among the highest-radon states in the country. The Minnesota Department of Health estimates that approximately 2 in 5 Minnesota homes have radon levels above the EPA action level of 4 pCi/L — and Hennepin County is no exception.
Radon is a naturally occurring radioactive gas that seeps into homes from the soil and bedrock beneath your foundation. It's colorless, odorless, and tasteless — impossible to detect without testing. Long-term exposure is the second leading cause of lung cancer in the United States, responsible for about 21,000 deaths per year.
If you haven't tested your Minneapolis home, or if results came back above 4 pCi/L, the EPA recommends mitigation. Radon Stoppers can typically reduce levels below 2 pCi/L — often down to 1 pCi/L or less.

Minneapolis Has Some of Minnesota's Oldest Basements -- and the Radon Risk to Match
Minneapolis has more pre-1960 housing than almost any other city in the state. Older homes -- particularly the bungalows, Craftsman-styles, and two-stories common across South Minneapolis, Northeast, and North -- have aging block or stone foundations with decades of settling, cracks, and deterioration that give radon gas easy entry points. Minnesota is classified as a high-radon state by the EPA, and Hennepin County consistently reflects that risk. The Minnesota Department of Health estimates roughly 2 in 5 MN homes test above the EPA action level of 4 pCi/L.
Renters and landlords in Minneapolis face a particular challenge: Minnesota's radon disclosure rules are limited, and many rental units -- including basement apartments and older duplexes -- have never been tested. Radon is a leading cause of lung cancer among non-smokers, and long-term exposure in an untested basement apartment is a real health concern. Radon Stoppers works with both homeowners and landlords to assess and mitigate residential properties across the city.
Mitigation in older Minneapolis homes requires experience with varied foundation types: fieldstone, concrete block, poured concrete, and partial basements with earthen floors. Radon Stoppers, LLC is NRPP-certified and has the expertise to design systems for Minneapolis's diverse housing stock. Call 763-222-9562 for a free assessment and estimate.
Radon Mitigation FAQs for Minneapolis
Are older Minneapolis homes at higher risk for radon?
Yes. Older homes typically have more foundation cracks, deteriorated mortar joints, and less effective sealing than newer construction -- all of which make it easier for radon to enter. Minneapolis has a large inventory of pre-war housing with stone, brick, and block basements. These foundation types are common entry points for radon and often require specialized mitigation approaches. Radon Stoppers is experienced with the full range of Minneapolis foundation types.
Does a Minneapolis duplex or rental property need radon mitigation?
Any property with a basement or slab-on-grade construction can have elevated radon, regardless of whether it's owner-occupied or a rental. Landlords in Minneapolis are increasingly asked by tenants and property managers to test and mitigate. Radon Stoppers works with rental property owners and provides clear documentation of post-mitigation results for tenant disclosure purposes.
How does radon mitigation work in a Minneapolis bungalow with a partial or stone basement?
Partial and stone-foundation basements require more careful assessment than standard poured-concrete basements. Radon Stoppers evaluates soil communication beneath your slab or earthen floor and designs a system that creates sufficient negative pressure to prevent radon entry. In some older Minneapolis homes, combination approaches using both sub-slab and sub-membrane elements are used. We assess each property individually before recommending a solution.
