"I had a really good experience with Tom O'Connor. He scheduled quickly and arrived on time. He had me stay with him during the inspection and pointed out things as we went along. He showed me problem areas, explained why they were a problem, and suggested how to fix them. He also reviewed maintenance of things like the boiler and air conditioning. His report arrived on the day he said it would be complete. When he returned in a few days to pick up the radon test he also completed a portion of the inspection of the roof that he couldn't do initially because of snow. His report reflected everything we had talked about and did include the home maintenance points as well. And the report is easy to understand. He confirmed for me that I was getting a good, solid house and that the things that need to be fixed are manageable."

"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.
