Get matched with top electrical wiring or panel upgrade pros in Marshfield Hills, MA

"Outstanding service. Less than one week from initial contact to completion of the job. Everything done in a professionally, neatly, and to code. No cutting of corners. Fair pricing and relatively quick (about 4.5 hours in total from beginning to end). They even went the extra mile and installed my 3rd party charger and tested it on the car. I'm very pleased and will be happy to call T&G again when I need electrical work done."

"Peter and his team did a panel upgrade for us when we bought our house in 2021. They completed tidy and well-labeled work on a tight deadline, exactly as planned, on one of the hottest days of the year. I was really impressed at the time with the clear communication about when they'd do different phases of work, what we needed to arrange with the town electric company, etc. More recently, one piece of conduit came unglued and they came by to fix it almost immediately, free of charge. I'm really impressed with this crew's standards."

"On time, very professional explained how and where he was installing my NEMA 14-50 receptacle - wired to electrical box. My new EV charger is working. Excellent - cleaned up work area - would 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."

"They came quickly and installed the tv in no time at all. They were professional, clean, respectful and friendly."

"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."

"We hired Zimbone Electrical to install our Tesla charger and would highly recommend the service. Professional attire/demeanor, punctual, fast & knowledgeable offering. Great price for this install, very happy customers. Christian even took the time to look at a couple of additional items. We will be calling on them again for our electrical needs. 5 Star Service."

"K&J updated our panel and outside wiring, which were in desperate need of repair. Kyle estimated the job, provided a written estimate and we agreed on a date (we needed a weekend and they were more than accommodating). Kyle and his partner Shane, showed up on the date, on time, answered any questions my wife or I had, and explained the whole process to us. They took roughly a half day to complete the job. Both areas (inside our basement and outside along the house) were as clean when they finished as they were when they started. I would 5 stars recommend K&J electrical for any work around one home."

"He was timely knowledgeable thorough and keep me informed of all he was doing. I plan on hiring him again in a few weeks to more electrical work!!"
