"Thorough and informative. Our inspector, Chris, was there before our appointment to unlock doors, turn on lights, and get acclimated with the house. The inspection lasted about 3 hours and Chris explained things as he went. Chris even made it on to the very steep roof. We received the report the very next day. The report was thorough and clear with pictures for every finding."

"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.

"It was a little tough to get in touch with John at first as he apparently does home inspections part time, but once I did he was very prompt and was very thorough in his inspection. He explained everything in a manner that I could understand and answered all of my questions without being condescending. If he's still doing home inspections when I look to buy another house I'd certainly work with him again."
