Radon Mitigation (Reduction) Contractor List for Wisconsin

Information about choosing a contractor

Get Certified!

Radon measurement and mitigation trainings are held in Wisconsin twice per year. To be listed here, contact Wisconsin's Radon Grant Manager, Jessica Maloney, at 608-267-7199 once you obtain certification.

Note to Consumers and Contractors:

There are no state regulations specifically for radon businesses in Wisconsin. The list below is combined from two national certifying organizations: American Association of Radon Scientists and Technologists (AARST), and National Radon Safety Board – Radon Proficiency Program. To be listed by these organizations, an individual must pass a national exam, meet continuing education requirements, maintain a quality-assurance program, and follow appropriate testing protocols. The websites for these two organizations provide the most up-to-date information.

In the table, each contractor listed for a county* also serves surrounding counties.
