Jeff Rubino and his team at JMR provide exceptional and intelligent service. I have worked with JMR Electric for many years. This year, they really went above and beyond. My wife and I had a huge roof leak at our three family house in Somerville. In the course of repairs, old knob and tube wiring was discovered. JMR worked with us, the Insurance company and Inspectional services so that we could complete the project quickly. They were very easy to work with and their work came in under budget.

Had electrical work done at my house and could not be happier with the experience. They were professional, on time, and explained everything in a way that actually made sense. The quality of the work was excellent and they clearly take pride in what they do. It’s hard to find contractors that are reliable, communicate well, and leave the place cleaner than they found it, but these guys did exactly that. Fair pricing, honest work, and no headaches. I would absolutely recommend them to anyone looking for electrical work done right.

Dylan and Joe were the best. They arrived on time and worked until the two thermostats were installed. They explained what they were doing and patiently showed me how to use the app on my cell phone. i would give them 6 stars. Gail Stein

Frequently Asked Questions

Yes, repeated breaker trips can indicate that electrical demand is exceeding what the existing panel or circuits were designed to manage safely. JMR Electric Group can assess service capacity, review circuit loading, and determine whether a panel replacement supports more stable power in older residential layouts.
Power is usually shut off for part of the project, but the exact duration depends on panel condition, access, and coordination needs. JMR Electric Group explains expected outage windows in advance so homeowners can plan around refrigeration, remote work, and other daily household routines.
After completion, homeowners should expect labeled breakers, tested circuits, and a panel better suited to current household use and added electrical loads. JMR Electric Group reviews the completed setup, helps identify which areas are tied to each breaker, and supports a smoother transition back to normal use.
