Radon Contractors/Mitigation Service Providers

Interested in becoming certified radon measurement or mitigation professional?
The University of Minnesota offers radon courses for professionals.

What to Look for in a Radon Mitigation Contractor/Service Provider

Minnesota does not require radon mitigation contractors to obtain certification or licensure, nor is there any oversight of mitigation work performed. There are a couple of different consumer protection-related resources for homeowners to check when hiring a radon mitigation contractor. These agencies can also take complaints from consumers. 

Minnesota Attorney General’s Office Consumer Complaints
Better Business Bureau

If you have a complaint about any radon-related activity, please contact the MDH Indoor Air Unit at health.indoorair@state.mn.us or by phone at 651-201-4601 to discuss your issue.

Although it is not required, a voluntary certification does indicate that the individual has received radon mitigation training and has taken continuing radon education. Both the National Radon Proficiency Program (NRPP) and the National Radon Safety Board (NRSB) have voluntary certification programs for radon mitigation contractors. For more information regarding the requirements of these certifications, information regarding a specific listed contractor, or an updated list of certified professionals, please contact NRPP or NRSB directly.

Properly designing and installing a radon mitigation system is a professional level activity. This will insure the final system is properly located and sized to achieve optimal radon reduction and not cause any other potential issues with the structure. Only radon professionals on the MDH list should be hired to do radon mitigation. Be certain the individual hired visits the jobsite prior to beginning any work to give you a solid proposal for mitigation. Bids should not be made over the phone or by email. Also make sure the certified individual will be the one on-site doing the work on your house. 

Due to the recent increase in radon testing in Minnesota, consumers need to be aware of uncertified individuals conducting radon-related work. Be aware of 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. Be sure to get a firm price and avoid hidden fees for future work when it may become necessary. Also, 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.

One final point, individuals are certified, not companies. Companies should not be advertising or otherwise claiming they are certified. Be certain the person doing the work on your house is certified to do the work.

What are some of the key questions to ask a mitigation contractor?

  • Will the contractor perform diagnostics to determine the suction point location and correct pipe and fan sizes?
  • Who is responsible for obtaining permits, if required?
  • Will a contract be provided?
  • Who will do the licensed electrical work?
  • Is there a warranty on materials or the workmanship? If so, for how long? Do they warranty system performance?
  • How will the system be evaluated?
  • Will the contractor offer the homeowner training in the radon mitigation system operations and/or troubleshooting?
  • Will the contractor guarantee that radon levels will be brought to below the Environmental Protection Agency's (EPA) recommended action level of 4.0 pCi/L?
  • What will the contractor do if post mitigation radon levels are not below the EPA's recommended action level?
  • Can the contractor provide a list of references and their individual certification number?
  • Is the quoted price guaranteed?
