Keystone Mechanical Group Inc.

Keystone completed an unexpectedly difficult install of a fireplace at my home. They went above and beyond to make the install work - running a new gas line when they couldn't tee off an existing one, and installing the exhaust vent in such a way that it minimized the protrusion into the living space. They were also far more reasonable in cost (for the unit and install) than the top rated competitor. I'd gladly recommend their work!
