Radon Measurement Contractor List

High Radon Level? Consult the Certified Radon Mitigator Proficiency List

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.

Consumers and Contractors Note: 

There are no state regulations specifically for radon businesses in Wisconsin. 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 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.  Their websites carry the most up-to-date information.

Wisconsin-based lab that will provide test kits by mail or phone.
