JMR Electric Group

JMR Electric Group, based in Stoneham and led by Jeff Rubino, has built an unusually deep and consistent record on Google — 5 stars across 89 ratings, with dozens of detailed accounts stretching back to 2021. Ed Costa comes up again and again for fast, clear scheduling, alongside a rotating crew — Guy, Dylan, Joe, Matt, Trung, Zach, Charlie — named on job after job. The work described is real electrical scope, not vague praise: 200A service and underground service upgrades coordinated with town inspectors, full-house rewires during gut renovations, EV charger installs, and knob-and-tube removal. Reviewers also credit fast emergency response — an electrician and apprentice dispatched within the hour for one urgent call, a post-flood repair finished within a day for another. Recent 2026 reviews keep the same thread: recessed lighting and a kitchen safety update finished in under a day, a same-day dimmer-switch fix, a commercial oven install for a cafe. Several customers describe using JMR repeatedly across multiple properties and projects over several years. One December 2024 reviewer was the exception, describing "significant mistakes" on a large project that the crew worked to clean up and rectify — while still recommending the company. With this much repeat business, JMR reads like a shop that has earned its regulars; still worth confirming current licensing directly and getting a written estimate before a big job, as with any contractor.
