"Dave first off cares about his customers health and well being. He is interested in solving your Radon issue and making sure the work is high quality. He pulls proper permitting for electrical and his support team is awesome. The other Radon company that was used did not meet specific standards in doing Radon migitgation work. Do your homework and read reviews before hiring a Radon company and check certifications: https://nrpp.info/. Dave takes his profession seriously and has a tremendous background in this work. I highly recommend Advanced Radon Technologies."
