Its stated service area includes Easton, Foxborough, Norton, Walpole, Needham, Attleboro and Taunton. A recent customer who has used GMB for years wrote that if George says he will be there around 4:00, he is there around 4:00, and also recommended his colleagues Alex and Mike. Another recent customer found George reliable and knowledgeable about the electrical issue in their house. In 2025, George and his team installed recessed lighting in a home; George also replaced that customer's hallway fixtures, replaced a door lock and installed a vanity mirror. In 2024, a customer used GMB for their central A/C install. In a separate 2024 review, George fit a customer in on the same day for an emergency call and pinpointed the problem. In 2013, GMB installed 11 new recessed lights, new center lights and a closet light in a home before the customers moved in, starting promptly at 7am. In 2025, a customer who hired them to remove an unsafe electrical box and replace it with one up to code wrote that when they had the work inspected, it was not where it needed to be, and bringing it up to code cost them over $1,000 extra. A 2020 BuildZoom review complained about a deposit that was not returned; the company replied that it had never done business with that reviewer.
Typical Greater Boston range for this kind of work, from regional averages — not a quote from GMB Electrical Service, Inc.. Use it to sanity-check bids, then get the real number in writing.
Standard receptacle swaps — a new dedicated circuit is a bigger job ($350–$750).
Flush mounts, pendants, chandeliers — hung on existing boxes.

Excellent customer service. George was reliable and extremely knowledgeable about the electrical issue in my house. I highly recommend!
I have been using GMB Electrical Service for years now... for a reason. In my experience, very few specialists, contractors, etc. are punctual, great communicators, take pride in what they do and are also highly quality conscious. George is all of this. He is personable, cares about and values his customers and always comes through. If he says he will be there around 4:00, he is there around 4:00. With demanding schedules, this is huge to me and I know the job will be done right. I highly recommend George (GMB Electrical) and his colleagues (Alex and Mike).
I hired GMB Electrical Service to install recessed lighting in my home, and I couldn't be happier with the results. George and his team arrived on time and completed the job efficiently and professionally. The pricing was very competitive, and George’s customer service was exceptional. In addition to the lighting installation, George kindly replaced my hallway fixtures at little to no extra charge. He went above and beyond by also replacing my door lock and installing a vanity mirror after my locksmith canceled last minute. Both tasks were done excellently, and at a fraction of the cost a locksmith would have charged. I’m incredibly grateful for George's extra help and the quality of his work. I highly recommend GMB Electrical Service to anyone needing electrical work!
Great service. Reasonable charge. Knows his stuff. 6 star rating Neil Mattera
The actual electrician who came out was very personable and friendly. That being said, they were hired to remove an unsafe electrical box and replace it with one that would be up to current code status. We paid for this service and they came out and did the work and we parted way amicably…that is until I wanted to get the work inspected to ensure everything was where it needed to be. Suddenly, all out work that was done wasn’t where it needed to be and we were forced to have them come out AGAIN to do the proper work. This would not have been an issue if they simply came out and fixed their issues, HOWEVER, now the work would cost us additional funds. We went into this expecting to pay a certain amount, we shopped around and got everything priced out and we were excited to give them our business. To bring their work up to basic code inspection cost us over $1,000 extra. If you are looking for someone to do electric work look elsewhere. They will do some of your work and then either by mistake or by acting in a malicious way, you will be on the hook for substantially more than you expected to pay. BUYER BEWARE.
