A dedicated 240V circuit run from a garage panel to a mechanical room, with the conduit run done cleanly and neatly along the wall — that April 2026 Google review is a fair picture of what Justin Mellor's North Grafton electrical outfit gets hired for. The same customer said the crew made repairs they hadn't known were needed and relabeled the whole breaker box with printed labels. A May 2026 reviewer had an EV car charger and a sub panel installed. Its Massachusetts electrician licence, #13520-EL-B, is active, with Justin P Mellor as the holder of record. The company's own site cites License # 13520B and says it is insured and offers free estimates. All 13 Google reviews, written from 2023 to 2026, are five stars. Older ones fill in the range. In a February 2025 review, a condo landlord described Justin confirming a dead microwave was the appliance and not a bad breaker, scheduling around the tenants, then returning to install the replacement. A September 2024 reviewer had recessed lighting and a "difficult" chandelier designed and installed by Justin, his brother and a third worker, who arrived early and cleaned up afterward. A February 2024 review credits Justin and "his electrician brother Rob" with planning and installing an EV charging station at a fair price. The bigger jobs show up in 2023. In a March 2023 review, a homeowner described what amounted to a new construction installation with an upgraded main service, plus a transfer switch and subpanel for a future backup generator; the dates Justin gave were met or beaten, and the customer wrote that the city electrical inspector was impressed by the layout. Another 2023 customer listed outlet and switch replacements, a total kitchen renovation and rewire, and recessed lighting over several visits. Price comes up in several reviews, each time described as fair or reasonable.
I’m not really one for writing reviews but this team is legit. I had a car charger installed for my EV and the work was excellently completed. I also had a sub panel and some other things installed. Super professional team. Can’t recommend enough.
Justin and his team did an outstanding job installing a dedicated 240V circuit from my garage electrical panel through to my mechanical room. From start to finish they were professional, on time, and clearly took pride in their work. The conduit run was done cleanly and neatly along the wall — it looks like it was always meant to be there. What really impressed me was that they went beyond the original scope. They identified and made repairs I wasn't even aware were needed, and took the extra time to relabel my entire circuit breaker box with clean printed labels — something I had been meaning to do for years. The quote was fair, the communication was great, and the finished work exceeded my expectations. I wouldn't hesitate to hire Justin and his team again for future electrical work and will absolutely be recommending him to neighbors and friends. Highly recommend!
I am extremely happy with the work done by Justin and his crew. Prices are fair and the workmanship is top-notch!
I reached out to Justin recently when the microwave in a condo I own in Lordvale Acres died. Justin went by and verified that it was in fact the microwave, and not a bad breaker. He coordinated his schedule around my tenants, which was very helpful. He was on time, courteous, and communicated very well. Once I had found a replacement microwave, he returned to do the installation for me. Again, working around my tenants schedule. I could not be happier with the quality of his work, his professionalism, and the pricing that he charged for the services he provided. I would highly recommend him.
Excellent Quality and Customer Service! Justin and his team are reliable professionals that have performed many jobs for our house to include running a new circuit, fixing broken overhead lighting, installing new electrical equipment, and inspecting/certifying aspects of our antique home. It is always a relief to work with this team as they are beyond trustworthy and more than reliable. Highly recommended!
