Stephen J. Duffy

Duffy Electrical has been wiring houses around Lynn since 1933 — 93 years, by the company's own account to the BBB — and is listed there as a six-person sole proprietorship with Stephen J. Duffy as owner. The permit trail backs up the longevity: 68 permitted jobs on BuildZoom, five of them in the past year, with the site's own read of those permits being that electrical work is what he mostly does. Sampled permits from 2018 to 2025 are the bread and butter of a residential electrician — service upgrades, new services, kitchen wiring, a generator hookup — spread across Nahant, Beverly, Peabody, Salem, Brookline, Newton, Topsfield and Holden. BuildZoom scores him 96, which it places in the top fifth of Massachusetts contractors. Two things to raise on the call. The BBB grades the business C+ and gives the reason plainly: failure to respond to one complaint filed against it. The complaint itself isn't described, so ask him about it. And the licence picture is layered — BuildZoom lists a Massachusetts electrician number, 21790, a construction supervisor licence CS-107656, and a home improvement registration 177644 issued in February 2026, all as records it says it verified active, alongside an older home improvement registration, 146708, that Massachusetts consumer affairs shows as inactive and at one point cancelled. Those are a directory's records rather than a registry check of our own, so ask for his current numbers and confirm them with the state. Neither page carries a single customer review, which is unusual for a business this old and leaves the case for hiring resting on the permit history and whatever references he offers. A reasonable call for a panel upgrade or a whole-house rewire from someone long established in the trade — get the complaint story and the licence numbers settled first.
