“Dave installed an active radon mitigation system for us 11 years ago when we bought our house. When the fan motor failed within the 5-year warranty period, he happily replaced it for free with no questions. That replacement motor lasted 8 years, and we just had him out to replace it. I would have expected his fee to increase over the last 11 years, but it didn't. Since this motor runs 24/7, I was surprised that we got those 8 years out of it. Dave spent plenty of time with me discussing another radon mitigation issue which he then fixed at no extra charge. He encouraged us to get another radon test and promised that if there was any problem he'd fix it for free. It is very rare to run across anyone who stands behind his work as well as Dave does. I recommend without hesitation.”

“It was completed flawlessly. From the moment I spoke to Dave through the quote process and the implementation, it was totally professional. The area around the system is neat, caulked, and perfectly clean.”
