Brian M Doherty

Pull the permit list for Brian M Doherty and one kind of house keeps showing up: the older one, with wiring nobody wants to touch. Knob-and-tube removal and re-feeding at 47 Pond St in Nahant in January 2021. A $50,000 whole-house rewire in Brookline in July 2025. A kitchen and living-area rewire in Belmont in February 2025. He works out of 20 Elm St in Chelmsford, with Brian L Doherty and Brian M Doherty listed as the owners, and the permit history is long — 147 projects on BuildZoom, at least ten of them in the past three years. BuildZoom scores him 101, which it places in the top 12% of the 139,240 Massachusetts licensed contractors it tracks. Six of those permits are in Nahant alone. Besides the Pond St knob-and-tube job, there is a service replacement after water damage at 20 Rollins Ave in March 2024, an EV charger and a broken-wire repair at 182 Wilson Rd in April 2024, a GFI outlet for a water filling station at 198 Nahant Rd in July 2024, bathroom and laundry outlets at 18 Emerald Rd in February 2022, and a detached-studio sub-panel with bathroom wiring at 15 Fox Hill Rd in August 2020 — an older house handled one circuit at a time. The paperwork is worth a question or two. BuildZoom lists a Massachusetts Construction Supervisor licence, CS-057980, and three Newton city registrations — Building Contractor and Residential Builder under #213608, Electrical Contractor under #31892 — recorded with 2022 expiration dates. A BBB page for Doherty Building & Design, same Chelmsford address but a different phone, has been open since 2004 and puts the business's start at 1997; BBB lists it as Not Rated, saying it does not have enough information to issue a rating. For a rewire, a service or panel replacement, or getting knob-and-tube out of a house built long before anyone owned a microwave, this is a permit history built on exactly that work. Sort out which of the two phone numbers reaches him, and ask whether the Newton registrations matter for where your job is.
