Although we interviewed about 4 to 5 plumbers total, as soon as I had Jamie come to the house I knew I had found the right company. He talked about the project like he was really trying to find the right balance between doing it right but also doing it to fit our budget. Master Mechanical handled all the permit issues from start to finish, while other companies told me I had to do this myself. The office staff, especially Rosemary, always e-mailed or called me back very quickly when I had a question. And then when the work finally started, the guys that came to do the job were professional, courteous, and did an excellent job making everything neat and clean. They even did a couple of side things for me and it was great as well. I plan on using Master Mechnical for all my future heating/plumbing needs. I will also be using them to insulate my home as well. I highly recommend this company to anyone considering having heating/plumbing work done in his/her home.
Update 10/2017: Had Master Mechnical/Green Homes come back and insulate my attic and rim joist using closed cell spray foam. Was a little nervous about this type of insulation since I had read on line if it is not done right it can cause a bad chemical reaction and make a big mess. But after the great job they did on the gas conversion I felt I could trust this company. And of course it went off without a hitch. The guys who did the job were very nice and tried to be as neat and clean as possible. They even helped us move some furniture into the house the happened to get delivered one of the days they were working.
