"Tom was wonderful and extremely thorough! He explained everything as he went along and I left feeling like I really knew the ins and outs of the property. He was extremely personable and very professional. He called to schedule and follow up prior to the date of the inspection. I felt confident in him during the entire process. I would recommend him to anyone."

"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.
