Find a Radon Mitigation Professional
Individuals conducting radon mitigation in Minnesota are required to be licensed by MDH.
If you have a complaint about any radon-related activity, please contact the MDH Indoor Air Unit at email@example.com or by phone at 651-201-4601 to discuss your issue.
Properly designing and installing a radon mitigation system is a professional level activity. This will ensure the final system is properly located and sized to achieve optimal radon reduction and not cause any other potential issues with the structure.
- Make sure the individual hired visits the job site prior to beginning any work, to give you a solid proposal for mitigation. Bids should not be made over the phone or by email.
- Make sure the licensed individual will be on-site doing the work or review the mitigation work completed at the end of the project.
- Avoid uncertified installers and inexpensive mitigation rates (less than $1,000). Price quotes promising really low installation rates are often too good to be true and leave the consumer with sub-standard workmanship and materials and a radon system that may not be working.
- Get a firm price and avoid hidden fees for future work when it may become necessary.
- Do not pay for the system in full before the work is complete. A valid radon test showing reduced levels should be obtained prior to full payment.
