Radon Testing, Mitigation Costs & Contractors in Minnesota

Minnesota homeowners are encouraged to test even when a home has been tested before or already has a mitigation system. Cold-climate conditions and building changes can affect radon measurements over time.

Testing your home

Minnesota Department of Health recommends testing the lowest level used as living space and provides follow-up guidance based on the result. For real-estate or professional testing, use an appropriately licensed professional.

Free or low-cost test-kit information

During Radon Action Month and other local programs, Minnesota public-health partners may provide kits at low or no cost. Kits are also available from retailers and laboratories. Verify local availability before showing a free offer.

Programs and inventory can change. Confirm current availability with the listed agency before relying on an offer.

Mitigation cost planning

Estimate only: a professionally installed residential radon mitigation system often falls in a broad $1,200–$3,500 range, but the final price can be lower or higher. Foundation type, crawlspaces, finished basements, multiple suction points, fan/pipe routing, electrical work, permits, diagnostics, and post-mitigation testing can materially change the quote. Use local written bids rather than treating this range as guaranteed pricing. State reference: Minnesota Department of Health states that professional mitigation generally ranges from about $1,500 to $3,000; local quotes still control.

A test result provides important context, but it does not directly increase the modeled price.

Minnesota rules and public resources

Verified: Minnesota requires licenses for professional radon measurement, mitigation, mitigation companies, and radon analysis laboratories as defined by state law and rules. Verify a specific license in the MDH system before displaying it.

EPA radon-zone context

Minnesota has widespread radon potential. EPA zones and statewide averages are planning context only; test the individual home.

Testing is the only way to know. EPA radon zones are broad planning tools. Never use a zone, county, ZIP, or map to predict the radon level of a specific home or to decide that testing is unnecessary.

Frequently asked questions

Should every home in Minnesota be tested for radon?

Testing is the only way to know the radon level in a specific Minnesota home. Maps, county averages, a neighbor's result, and foundation type cannot replace a properly conducted test.

What does a result of 4 pCi/L mean?

EPA recommends taking action to reduce radon at 4 pCi/L or higher and suggests considering action between 2 and 4 pCi/L. The action level is not a line between safe and unsafe; long-term risk generally increases as exposure increases.

How much does radon mitigation cost in Minnesota?

Pricing varies by the home and the system design. RadonCostGuide uses broad planning estimates only; foundation type, crawlspaces, finished areas, suction points, electrical work, permits, diagnostics, and post-mitigation testing can all affect the final quote.

How do I find a radon professional in Minnesota?

Start with the state radon program and the NRPP/NRSB directories where appropriate. Independently confirm current credentials, insurance, scope of work, permits, warranties, service area, and pricing before hiring.

Are free or low-cost radon test kits available in Minnesota?

During Radon Action Month and other local programs, Minnesota public-health partners may provide kits at low or no cost. Kits are also available from retailers and laboratories. Verify local availability before showing a free offer.
