We had a great experience with Radon Detection Control. We were selling our home & needed to have a system installed for the sale. We messed around with another company for two weeks. I contacted RDC through home advisor & they installed our system in two days. They had to put it in a difficult place but worked with us & did a great job. Larry & Paul were excellent to work with as well as the office ladies. We received a quote and guarentee via email prior to the installation along with paperwork to pass along to the buyer. They put my mind at ease & did a great job. ??
