Petersen Electric

One customer kept calling Dave Petersen back for five years straight -- three separate remodeling jobs in an older Rochester-area home -- and by 2023 they were calling him their "go to guy" for electrical work. That kind of repeat business says something a single star rating can't. Petersen Electric is a one-person shop run by owner Dave Petersen out of Rochester, MA, working South Coast towns -- Marion, Mattapoisett, Wareham, Bourne, and Fairhaven -- with residential and commercial wiring, generator installs, and new-construction electrical work. The company describes itself as roughly a decade into the business, though its Better Business Bureau file, accredited at an A+, lists 22 years in business. On Google, a dozen ratings average five stars, and the reviews that spell things out point the same direction: prompt, thorough, reasonably priced. A 2025 review describes Dave showing up right on time for a new electric mast install and doing the job "flawlessly"; another calls him dependable and reasonably priced "over the years." The BBB profile lists generator installation, commercial and residential wiring, new construction wiring, and outdoor lighting among its services. There's a small gap worth asking about: the company's own site describes itself as under 10 years old, while BBB's file puts its start date at 2004 -- worth a quick question about which reflects the current shop. For a South Coast homeowner who wants one electrician for the long haul rather than a rotating cast of subcontractors, the repeat-customer pattern here is the strongest signal. Confirm current pricing up front, since the reviews call it reasonable without giving numbers.
