Iannazzi Electrical Services

Ninety-nine permitted projects sit under this Andover company's name on BuildZoom, most of them commercial electrical work at a typical permit value near $13,000. That's the clearest read on what Iannazzi Electrical Services actually does day to day: it is a contractor shop first, not a residential service-call outfit. The company describes itself as an electrical services, construction and consulting firm handling both residential and commercial work, plus low-voltage systems — fire alarm, security, video surveillance, data wiring. It tells its own story as a third-generation family business, tracing back to Michael J. Iannazzi in 1945, with William J. Iannazzi learning the trade from his father in the 1970s and still guiding the third generation. The Better Business Bureau's file is more specific about the corporate entity: William J. Iannazzi, Inc., incorporated in 1989, 30 employees, A+ but not BBB accredited, with no complaints and a stated one-year warranty on services. The website's claim of 81 years reaches back to that 1945 origin rather than the incorporation date, so expect the two numbers to differ if you ask. The customer-facing record is where it thins out. Four Google ratings averaging 4.8, and the written accounts on file are dated — the newest is from 2020. BuildZoom scores them 101, which it places in the top 12% of Massachusetts licensed contractors, and its permit-record page carries no reviews at all. So the volume of real work is well documented; what individual homeowners thought of it is not. On credentials, be careful how you read the directories. BuildZoom lists a stack of Massachusetts electrician and electrical-business licence entries under the company — several it marks active and says it verified in spring 2026, alongside others it shows as inactive or cancelled, and a few carrying expiration dates already past (a Massachusetts master electrician entry dated to 2016, a City of Newton contractor entry to 2022). Those are the directory's own records, not a state-registry check, and a busy multi-licence shop routinely accumulates lapsed municipal entries. The company separately says it is licensed in Massachusetts, New Hampshire and Maine and that its employees are OSHA certified — its own claim. Ask for the current licence number of the electrician who will actually be on your job and confirm it with the state yourself. They are a reasonable call for larger residential jobs, panel and service work, or low-voltage systems where a 30-person shop with a long permit history matters more than same-day response. For a small emergency repair, a residential-focused electrician may suit you better.
