"When Eversource relocated my gas meter, they discovered several â violations", and shut off the gas (this was in January). Tim agreed to come out the following day. He arrived with two trucks and two men, ready to work. Needless to say, I wasnâ t expecting such a response. After assessing the situation, the technicians solved my problems by noon. The workmanship was outstanding. I cannot recommend them more highly. They literally saved my butt."

"We hired Alan to replace several outlets in our house and assist with a dryer installation. He was a good communicator, was able to come soon and to work around our schedule, and was a knowledgeable and conscientious professional (he even brought coverings to wear over his boots in the house, a nice touch). I would gladly hire him again and recommend him to others in the Valley."
