"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."
