"I could not have been more pleased with Payne Electrical! From the scheduling to the installation, everyone I worked with was incredibly professional and made the whole process easy. I had two ceiling fans and a light fixture installed. The two electricians that came to my house were prompt and incredibly courteous, and very thorough in their work. They were also super kind about my small dog that wanted to keep barking at them... I would highly suggest this company to anyone in the metro Boston area, and will definitely be calling them for any future electrical needs!"

"Generators of Maine just completed the installation of a 14kw generator with parallel transfer switches, to protect 2 separate metered panels at a rental property that I own. I didn't even know that this was possible, until Doug Sawyer suggested it. The incremental cost of protecting the additional panel with the parallel transfer switch arrangement was a fraction the cost of an additional generator and transfer switch. Throughout the job, Doug and his crew were awesome. I am a terrible snoop who enjoys technology, so I hung around just watching and learning. They didn't seem to mind my presence and were friendly and informative through out the install. Every aspect of the job was 100% top-notch. Doug also managed to under bid his nearest competitor on every component and aspect of the job, including the annual maintenance contract, which I deemed to be worth the $$$. I highly recommend Generators of Maine."

"This was to install a standby generator. The advance planning was excellent as was the quality of the work. Customer service is outstanding. Price was high, however. LaPlante was the highest of 3 bids received. Nevertheless, I selected them because of their professionalism and customer service."
