"He was excellent, arrived on time and did project quickly and the price was right ! I highly recommend him !"

"Matt and his team did an excellent job upgrading our electrical panel. He coordinated the work with National Grid, relocated the panel, labeled the circuits and tested all the work. I would highly recommend Dever Electric."

"We had a serious issue apparently caused by a bad connection in our wiring. Lights were dimming, flickering and several appliances had failed. Dan came by on time the next day. ( I had contacted him around 4:00 PM the previous day). He investigated the problem thoroughly, and so far the issue has not returned. If it does, I will call him again. This type of problem sometimes is not a black and white issue, but he spent a good deal of time and checked everything. His charge was very reasonable considering the time he spent."

"Chris handled a wiring job for a new screened porch and deck addition. It ended up being fairly complex due to high-wattage radiant heaters and a specialized control panel to allow them to be dimmed. Chris did a great job mounting and wiring everything, was very timely, and responsive. Since I was remote, he texted me photos so that I could appove of location of installations when questions arose. Will use again!"

"Great experience. Professional and on time. Knows what he’s doing, and is very straightforward. The work involved running wires through walls and from the basement panel as well. He did minimal cutting of the walls. Super happy with the work done. Would definitely hire again."

"Cotti-Johnson was superb. We had long wanted a permanent generator attached to our house but delayed due to the hassle (buying a generator and then finding all the separate contractors needed to do the electrical and gas work). Cotti-Johnson was one-stop shopping. They did it all, including arranging for the final inspections. They responded to our inquiry right away and within weeks, our generator was fully installed. They also upgraded our electrical panel (long overdue). Kudos to Eric for assessing our needs and E. J. and his co-workers for their efficient and excellent work in installing both the generator and electrical panel."

"Jim was very helpful. The TV had a problem with it when he mounted it. He took it down from the mount and called the company for a service call. I would definitely hire this company again. He was very professional, showed up on time and cleaned up after his work."

"Came on time. Checked out the electrical problem with our clothes dryer and gave me an estimate. He went right to Home Depot to get new wiring and came right back and fixed the problem. Excellent service and will use him again."
