“I have been exceptionally pleased and completely satisfied with every aspect of GEM’s work and every one of their employees has gone above and beyond for me. They are all very thoughtful, kind and considerate. I had a complete electrical upgrade, as nothing was up to code in the home I bought. I put in a completely new HAVC system, a tankless hot water heater and a full house generator.”

— Melissa Jones, New England
