JM Electrical Company, Inc

JM Electrical is a family business now on its third generation — a 2026 profile marking the company's 40-year milestone describes founder Paul Guarracino's sons Matthew, John, and Andrew carrying the business forward, with Matthew summing up the approach as wanting "to make every customer a lifelong customer." Based in Lynnfield, the company (self-reported founding in 1985, and on its own site: "since 1985... a trusted name in the commercial development sector") is built for commercial and industrial electrical work — building automation controls, instrumentation, mechanical power tie-ins, and energy projects like EV charging and solar controls — rather than typical homeowner service calls. That same anniversary piece credits the company with roughly 25,000 completed projects and six million work-hours, plus a national safety distinction: the National Electrical Contractors Association ranked it the ninth-safest electrical contractor in the country. Written reviews are sparse but line up with that reputation — Google shows 4.2 stars from 11 ratings, and a customer writing on LocalityBiz called the work "professional," said an appointment was made quickly, and added they'd call again for future jobs. Angi lists a 5.0 rating, but of its four reviews, one is actually a mismatched write-up describing an unrelated cellphone-repair shop rather than JM's own work — worth knowing if you're leaning on that number. Because the business is built around commercial and institutional clients, what's on record speaks more to complex commissioning and mechanical-contractor coordination than to small residential jobs. For a routine home electrical fix, this isn't obviously the first call; for a larger commercial or building-automation project in Greater Boston, the four decades of history and the safety ranking are the real selling points — worth confirming current project capacity and typical job size directly with them before booking.
