"In additional installing a new entire switch panel, we had a plan to install a generator, but when we bought a new house in a town 40 minutes away we decided to move the generator installation to the new house and they allowed us to cancel the planned install, just three days before initial install, and reschedule the installation to the new house a good two months following the initial plan. Very flexible and supportive."

"Jason and his team with Cotti-Johnson did an excellent job updating our electrical boxes, installing the washer/dryer hookup, and getting us setup with a generator! Sam, our assigned electrician, even took the time to go through the entire operation of the generator from A-Z. I would definitely recommend them for any electrical work!"

"I am extremely pleased with Mike's work. Very professional, very responsive, Kept in touch during the bid and installation process. Very reasonable pricing, showed up on schedule and did excellent work. No surprises. I will definitely use his services again and strongly recommend him to others. Business is based in Sandwich, MA."

"Tim P, Generator Advisor, visited our house and gave on the spot estimatesâ ¦..he was GREAT. Licensed Electrician who knew his business and was easy to speak with. Timely communications and responses to text messages! Tim was helpful answering questions after the generator was installed. We talked to 5 Generac dealers and a Kohler dealer. Cotti-Johnson had the best pricing in the South Shore area. We highly recommend this company. If you are thinking about buying a standby generator, Cotti Johnson is the company to callâ ¦..Art V"
