Radon Mitigation in Central Minnesota
Central Minnesota runs from the granite bedrock around St. Cloud to the sandy lake country around Brainerd, and radon rides along the whole way. Stearns County is rated Zone 1 on the EPA Map of Radon Zones, and the Minnesota Department of Health reports that 2 in 5 homes tested statewide have radon levels that pose a significant health risk.
The region's counties treat radon as routine public health work: Crow Wing County gives test kits away for free in Brainerd. When a result comes back high, we connect homeowners in St. Cloud, Brainerd, and the surrounding towns with independent, MDH-licensed mitigation contractors for free written quotes.
Radon in Central Minnesota
Stearns County carries the EPA's Zone 1 rating, the highest radon potential category, and MDH's statewide numbers apply here with no discount: 2 in 5 tested homes high, and a state average more than three times the national average. County health agencies in the region actively push testing, including free kit programs, because the cold-climate mechanics are unavoidable: months of heating season pull soil gas into basements that people actually live in.

St. Cloud is called the Granite City for the 1.7-billion-year-old igneous rock quarried there for over a century, and central Minnesota's surface is a mix of glacial till and sandy outwash laid over that bedrock. MDH traces radon to the natural decay of uranium in rocks and soil; igneous bedrock regions and the glacial sediments derived from them are exactly where that decay chain lives. The permeable sandy outwash of the Brainerd lakes area also lets soil gas move easily toward foundations.

The housing mix runs from early-1900s rail-era homes with block and stone basements in St. Cloud and Brainerd proper, through postwar ramblers and split-levels, to lake cabins converted for year-round living, many on crawl spaces or slab additions. Crawl spaces get sealed membranes instead of slab suction points; conversions with mixed foundations sometimes need more than one. Homes permitted after June 1, 2009 include a passive radon rough-in under the state code that a licensed contractor can activate with a fan.

Verify Your Contractor's Minnesota Radon License
Before you hire anyone for radon work in Central Minnesota, check their license. The Minnesota Radon Licensing Act, Minnesota Statutes section 144.4961, requires anyone who performs radon testing, mitigation, or laboratory analysis for compensation to be licensed by the Minnesota Department of Health, and every mitigation system installed under the law must carry an MDH system tag. A licensed professional expects the question. Three things to ask before you sign:
- Can I see your current MDH radon license, and is the company licensed too?
- Will the installed system carry the MDH system tag required under the licensing law?
- Will I get a written, itemized estimate and a follow-up radon test that confirms the system works?
Central Minnesota Radon Questions
How do I get a free radon test kit in central Minnesota?
Crow Wing County Land Services offers free radon test kits at its Brainerd office at 322 Laurel Street, and other county health departments in the region sell kits at low cost. The MDH Local Radon Contacts directory lists the current program for every county.
Does granite bedrock mean more radon around St. Cloud?
Granite is an igneous rock, and MDH attributes Minnesota radon to uranium decaying naturally in rocks and soil. Stearns County's EPA Zone 1 rating reflects high predicted indoor levels. The practical takeaway is the same as everywhere in Minnesota: the geology loads the dice, and only a test tells you how your specific house rolled.
My cabin near Brainerd is on a crawl space. Can it be mitigated?
Yes. Crawl spaces are mitigated with a sealed soil-gas membrane over the exposed earth, with the suction pipe drawing from beneath the membrane. Converted cabins with a mix of crawl space, slab, and basement sections are common in the lakes area, and licensed contractors design around exactly that.
