"adon After I contacted him, he responded promptly. While evaluating the area that needed radon mitigation, he called to discuss an area that had not been evaluated by inspectors (not affiliated with him). After accepting his price, we agreed on the day for the installation. During the installation, he was respectful and communicative. After completing the installation, he provided written warranties for me and the buyer. I highly recommend Keystone Radon Mitigators.
