"The Buyer's Inspector was extremely thorough. I have heard it said that he is the "pit bull" of home inspectors. He left radon detection equipment behind for over 50 hours. He offered additional water testing at my request. He has provided me with a itemization of all things good, marginal, bad, dangerous of every aspect of my house. He cross referenced these comments with pictures and suggestions. He seemed highly knowledgeable. It will be easy for electrician, plumbers, chimney sweeps, etc. to understand and locate the problem areas in the home. But beware when you schedule: My inspection lasted 6 hours!"

"Mike did a great job and did it for a great price. I was a little disappointed at the mess left behind that I had to clean up. That said, I would recommend Mike to anyone needing a radon mitigation system."

"SWAT did a great job installing the radon mitigation system in my house. They were very responsive, coming out quickly to provide a quote and offered a discount if the neighbors in the connecting townhouse would sign on as well. Installation was quick and the system was installed with no problem whatsoever. The radon levels in my house dropped from a reading of 12 to “undetectable” in just a couple of weeks."

"Mike and his daughter performed the inspections. He was responsive to my questions and doubts and was able to set up the appointment for the next day. I would have expected that the smoke detectors along with the doorbell to be tested - I didn't think of this until after the inspection. I did ask him to check some of the lights (porch, closet) that maybe would have been missed. Price was higher than most but he was able to accommodate my timing."
