"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!"

"The inspection was incredibly thorough with an excellent report provided. We learned a lot about the house and Matt was incredibly knowledgeable. We are buying this house built in 1893 with the confidence to know all positives and any problems we may run into. Septic system was inspected extremely well. We were also provided a visual look at Seawall and dock including a test of the boat hoist."
