"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."

"Paul cam to assess the mold on my basement walls and he didn't just come in a look. He went above what we thought he'd do and inspect the baseboard in the entire basement. He also checked oitsode to see where the moisture could be coming in from. He was very efficient and helpful with providing information on air filters, remediation, and potential causes and how to prevent. We would use him again."

"The rep came out and reviewed the areas of concern. He gave me an estimate on the spot. The next day I decided to go with JBH and the project was scheduled for the following week. The workers arrived within the scheduled time period and they were very pleasant to work with. They were responsive, efficient and neat. The job was completed in no time.

"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."
