"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!"

"Christian Zimbone presented a very competitive bid on our project to upgrade our electric service and installation of an electric car charger. He came in on budget and did a phenomenal job. Everything neat, clean, and 100 professional looking. He was very responsive, informative, and very friendly to work with. He knows his stuff! (...and we had several other estimates with varying dubious info). Highly recommend and will definitely hire again for any future needs."

"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"
