“Chris and his team helped refresh the interior of our 50 year old house. They were very professional and did fantastic work. Contractors who are easy to work with are hard to find, but Chris was just that.”
“A few years ago, Gamache also did a sunroom addition for us, as well as replacing all of our windows and replacing a bathtub with a walk in shower. We were very happy with that work, also!”
