Radon Mitigation Services
Professional, certified radon mitigation for homes and businesses across Minnesota and Western Wisconsin.
What Is Radon & Why Does It Matter?
Radon is a naturally occurring radioactive gas that forms from the decay of uranium in soil and rock. It seeps into homes through foundation cracks, gaps, and openings — and because it's colorless and odorless, you can't detect it without testing.
Radon is the second leading cause of lung cancer in the United States, responsible for approximately 21,000 deaths per year according to the EPA. The EPA recommends action if your home tests at or above 4.0 pCi/L.
The good news: radon is entirely preventable with a properly installed mitigation system. Over 90% of systems we install reduce radon to below 2 pCi/L — well under the EPA action level.
