Radon Contractor Licensing in Montana
Montana licensing
Montana does not require a state license or certification for radon mitigation contractors. The Montana Department of Environmental Quality Radon Control Program publishes lists of radon service providers as a convenience but does not certify the contractors listed. Look for national NRPP or NRSB certification, gather several written bids, and check insurance and references.
