Nearly every account of Booker Electrical circles back to the same machine: a Generac standby generator. Homeowners from Cape Cod to Medford describe the same sequence — someone comes out and measures for an accurate estimate, the proposal gets walked through question by question, the company handles the permitting and the inspection, and the unit goes in. Across 42 Google ratings the average sits at 4.9.
The Mansfield company is run by William Booker, and its Massachusetts electrician licence #22110 is active on the state registry with him as the holder of record. BBB, which has had a file open since February 2019, grades it A+ — though it is not accredited there, and BBB lists the business as started 12/23/2015 with a single employee. Its own site names Mansfield as its base and describes it as an authorized Generac sales and service dealer.
The work volume runs well ahead of the review count. BuildZoom's permit history reaches 306 permitted projects, 119 of them in the past three years, at a typical permit value near $11,000, spread across North Easton, South Easton, Taunton, Randolph, Braintree, Brockton, Attleboro and Chestnut Hill. On Procore, where the profile is claimed, the company lists 13 projects and puts itself in both the commercial and residential sectors.
What customers return to is response time. In a January 2024 review, a homeowner whose generator failed twelve hours into a storm left a midnight voicemail expecting a morning callback and had a technician troubleshooting that same night. In an April 2024 review, a commercial customer had a building upgraded to three-phase and a spray booth wired, and wrote that the crew showed up when they said they would and held true to the quote. Reviewers through 2023 and 2024 name the same people over and over — Brandon, Cameron, Jake, Steve, and Pam and Lucy in the office.
Two things are worth pinning down. In July 2026, a customer who had a shed rewired called the job clean and the electrician professional, but said the price came in above what they expected and that an inspection they waited for never happened. And in July 2024 someone left one star purely about the phone system, describing a menu loop that would not recognise inputs or forward the call to anyone.
If you are installing a Generac, servicing one, or inherited one with the house, this is the shop those reviews keep describing. Get the inspection date in writing, confirm the licence number that goes on your permit, and ask up front what the quote does and does not include.
