"John M. was courteous, timely, and professional in his inspection. He was upfront about the issues -- whether they are serious or minor, rare or common, and whether more specialized input is required. His written report was very well done and will serve as a great home guide for us in the future after we move in. Thank you!"

"Mike is absolutely amazing. We wanted our basement air tested so we can safely work there and he did all the tests and advised us on a number of things that have indeed greatly improved the air quality. He also volunteered to take a look through our house and he identified mold in our bathroom that I hadn't even seen! He told us exactly what to do to get rid of it and it worked. I highly recommend Mike."
