Colman Electric

Knob-and-tube removal sits on Colman Electric's list of everyday jobs, which tells you what vintage of Cambridge and Boston house it spends its days in. The family-run company says it was founded in the fall of 1976, and its Better Business Bureau page puts it at 50 years in business as a Cambridge electrician, graded A+, with electrician license #A9320 listed there. The work itself runs to residential and commercial repair, wiring troubleshooting and lighting installation across Boston and Cambridge. A Somerville homeowner wrote in July 2026 that their household had used Colman a few times and was happy with the work. In a February 2023 r/medfordma thread, a commenter said they had used Colman Electric for small add/replace jobs but wouldn't use it for anything too large or complicated, after a bad experience over the phone trying to communicate and schedule a medium-sized job. One thing to settle before you plan around them: in April 2026 someone in r/CambridgeMA wrote that they pass the shop from time to time and had not seen activity inside for a while, with the company vans missing from the street. For a dead circuit in an older house, or for finally pulling knob-and-tube out of the walls, this is the kind of shop set up for that work. Call first and confirm they are taking jobs and can schedule a visit, and look up license #A9320 on the state register before you sign anything.
