Radon Risk in Monticello & Wright 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 Wright 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 Monticello 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.

Wright County Homes Face Real Radon Risk -- And We're Right Here
Monticello sits on glacial till soils deposited thousands of years ago -- the same geology that makes Wright County one of Minnesota's higher-risk radon areas. These soils allow radon gas to move freely through the ground and into your home's foundation, whether you have a poured concrete basement, a block wall foundation, or a crawlspace beneath a slab. Because radon has no odor or color, most homeowners don't know they have elevated levels until a test reveals the truth.
Radon Stoppers, LLC is based here in Monticello. We've mitigated hundreds of homes across Wright County -- from newer construction on the west side of town to older ranch-style homes closer to the river. We know what foundation types are most common here, which neighborhoods tend to test higher, and what size system your home actually needs. That local experience means faster assessments, accurate quotes, and installations that work the first time.
The EPA recommends action when radon tests above 4 pCi/L. The Minnesota Department of Health estimates roughly 2 in 5 Minnesota homes exceed that level. If you haven't tested your Monticello home -- or if your test came back elevated -- call us at 763-222-9562. Most mitigation systems we install here reduce levels to below 2 pCi/L, often closer to 1 pCi/L.
Radon Mitigation FAQs for Monticello
How common is elevated radon in Monticello, MN?
Wright County, where Monticello is located, sits on glacial till soils that allow radon to migrate easily. Minnesota as a whole has elevated radon risk -- roughly 2 in 5 MN homes exceed the EPA action level of 4 pCi/L according to the Minnesota Department of Health. The only way to know for sure is to test. Radon Stoppers provides free estimates and serves Monticello and all surrounding Wright County communities.
Can Radon Stoppers schedule mitigation quickly for my Monticello home?
Yes. Because we're based in Monticello, scheduling and site visits are straightforward -- no long waits for a crew driving in from the Cities. Most assessments happen within a few days of your call, and installations are typically completed in a single day. We're familiar with the common foundation types in Monticello and can give accurate estimates without guesswork.
Do new construction homes in Monticello need radon mitigation?
Newer homes can still have elevated radon. Some new construction in the Monticello area is built with radon-resistant features (passive systems), but passive systems alone often don't reduce levels enough without an active fan. If your new home included a passive system, adding a fan is a low-cost upgrade that makes a significant difference. We test and activate passive systems for homeowners throughout Wright County.
