"I specifically wanted an inspector that would be honest with me and not just gloss over costly problems with the homes we planned to buy. I've heard a lot of inspectors don't like to be "deal breakers" who get blacklisted from the realtors. I was nervous about the first home because we knew it needed work, but we are first time home buyers and weren't sure just what we were getting into. Thankfully, we chose the right inspector. Tom was thorough and noted every problem with the house. He caught a slight bulge in the basement wall that wouldn't have been permitted with our FHA loan. Although the owners could have fixed it first, there were several other major things we hadn't caught. We decided to pass on that house and went with another. We thought the second time around we had made a more informed choice (and it was a more expensive house). But again, Tom caught several things we had not seen. I also made several follow up calls about the details of his inspection, and he returned my calls each time, patiently answering my questions and explaining additional information. We appreciated Tom's honesty, professionalism, and thoroughness."

"We had a few workers here most of the time, the technicians were prompt and prepared, and friendly, which made things run smooth. Because of this, when an option was given, we were able to ask which way would save time and money, and trusted their judgement. We are very satisfied with the work that was completed and they left the place pretty clean considering all the soot they had to work in.
