Certified Radon Measurement and Mitigation
Below is a list of contractors certified for measuring radon and reducing it. These contractors must pass a national exam, meet continuing education requirements, maintain a quality-assurance program, and follow appropriate testing protocols to be listed on this page.
Interested in becoming a certified radon measurement or mitigation contractor?
Trainings are held in Wisconsin twice per year; check the training page to get dates and locations. To be listed here, contact the Wisconsin Radon Grant Manager once you obtain certification.
Being listed on this page does not constitute endorsement by the State of Wisconsin or the Department of Health Services. The lists are provided as an additional resources for interested individuals.
Before You Begin
Wisconsin has no radon regulations. As a result, homeowners are best served by educating themselves as much as possible before hiring a contractor and having a system installed. Before selecting a contractor from the Wisconsin list, first read the EPA's How to Select a Contractor.
The following are some additional general tips for those who need to hire a contractor.
-
The certified individual must show up at the job site, at least to supervise, although they don't have to stay throughout the work. When inquiring about estimates, ask the person answering a call if the certified individual will be doing the work or at least inspect the system, and be sure he or she does.
-
The fan must be outside the basement and the exhaust stack must go up to the roof, at least 10 feet above ground and 2 feet above any windows less than 10 feet away. If the exhaust is released at the sill of a house, some of this radon can enter the house through openings at the sill plate (where the basement sucks it in), and potentially into nearby windows. Studies have shown the average indoor radon can be increased by 1 pCi/L or more by these effects. In addition, experienced EPA contractors show that the joints and couplings to radon fans tend to leak radon on the high pressure side, significantly reducing the effectiveness of mitigation systems with fans in basements.
-
For a list of mitigation system standards see the U.S. EPA booklet Consumer's Guide to Radon Reduction, or call a Wisconsin Regional Radon Information Center toll-free, 1-888-LOW-RADON.
