Radon Testing & Mitigation Services for Iowa and Wisconsin
Radon mitigation is not one-size-fits-all.
Every building is different, and the right solution depends on factors like the foundation condition, crawl spaces, pressure conditions, and existing HVAC systems. Depending on the property, mitigation may involve sub-slab depressurization, crawl-space depressurization, an HRV system, or other approaches. We can help you figure out exactly how much radon is present and where it’s coming from—and help you take care of it, too.
Residential Radon Testing & Mitigation
7 in 10 Iowa homes have elevated radon levels. Residential radon testing can give you peace of mind.
Your home should be a safe place for you and your loved ones—but Iowa has the highest indoor radon levels in the country, and radon is bad for our health. According to the EPA, radon is the leading cause of lung cancer among nonsmokers in the United States, and it increases the risk for smokers tenfold.
Because radon is invisible and odorless, testing is the only way to know if it is present in your home. TCO Radon provides professional radon testing for homes throughout Iowa and Wisconsin.
