"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."

"As a realtor, I found Rich from Expedient Environmental Solutions while searching for a client who needed mold remediation. He and his crew did an excellent job at a fair price. They finished on time and left the home clean. So, when I was looking personally to have basement waterproofing (interior french drains and sump pump) along with radon mitigation, I received 3 quotes, of which theirs was the most comprehensive plan, and again not the highest quote overall. They finished the work ahead of schedule by bringing four workers the second day, were respectful throughout and left the area reasonably clean. I'm confident that my days (and nights!) with the shopvac and flooded basement are finally over, and grateful they stand behind their work for a full year. Good contractors are hard to find. Glad I found them. Thanks and I highly recommend!"

"Mine was very meticulous and honest. I appreciate him doing a whole inspection when I only had a few issues needing a check up. He was not in a rush and made sure he checked every floor and room! I would friendly hire him again!"

We would highly recommend Inspect & Detect and would use them again."
