Our state-licensed radon technicians stand behind every system we install, guaranteeing indoor radon levels below 4.0 pCi/L for 5 years. With a team of experienced professionals, we are committed to delivering high-quality, efficient solutions tailored to each home’s unique needs.

Our story began in the late 1980s when Dave, a licensed plumber, and Vickie, a realtor, identified a growing need for radon mitigation in both new and existing homes. Together, they established Radon Reduction Systems, Inc., to provide reliable, effective solutions that protect homeowners from the dangers of radon exposure.
