I found Mark on homestars and am very satisfied with his work. Our installation consisted of a built-in fridge which was very difficult to move, a 6 burner gas range and a hood fan. The exterior opening for hood fan venting had been cut too small by another contractor and Mark was able to explain the implications. He came back for a second visit and modified the existing vent. His team is friendly and always clean up after themselves. Very positive experience and highly recommended.
