"Olivier was terrific. He was incredibly thorough and left no detail out of his inspection or his report. He took the time necessary to inspect all elements of the inside and outside of the home, he was patient in explaining what he found, and he was able to put all his comments within a helpful perspective. I would recommend him 100% and would use him again without hesitation."

"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."
