Coastal Electric Inc. runs out of Hanover on the South Shore, taking on the electrical work that comes with owning a house near the water — panel upgrades, generator hookups before storm season, and the kind of new-construction and renovation wiring that comes with remodeling projects. In 2018 and 2019 reviews across HomeAdvisor and Angi, the electrician behind the jobs, Pat, comes up by name again and again: called back quickly, showed up the same day he quoted, and left the site clean when he was done. A 2018 review describes him retrofitting an EV charger onto an aging subpanel — he checked whether the panel could handle the load, explained the upgrade path in plain terms, and walked the homeowner through the wiring afterward. Another from the same year describes wiring a generator hookup, and a third describes replacing four ceiling fans and an exterior motion sensor light in a single visit. Both platforms show a perfect 5.0 average across 28 ratings, and all but one of the specific reviews on file are five stars — the one exception, a December 2018 review, still landed 4.5 with no complaint attached. One 2018 reviewer mentioned weighing some negative reviews found elsewhere before deciding to hire anyway, calling the experience nothing like what those accounts described; no negative account itself appears in what HomeAdvisor or Angi publish here. Worth knowing before calling: the written reviews on file run from 2018 to 2022, so recent feedback is thin, and Angi's own badge marks the profile "Not Angi Approved" even though the rating itself is perfect — worth asking directly about current wait times. HomeAdvisor and Angi both cite 12 years in business and list generator installations, new construction, renovations, and service upgrades among the work offered. For a South Shore homeowner with a generator, an EV charger, or a remodel that needs an electrician who explains the work before doing it, the reviews describe exactly that. Confirm current scheduling and get a firm timeline before booking.
Typical Greater Boston range for this kind of work, from regional averages — not a quote from COASTAL ELECTRIC. Use it to sanity-check bids, then get the real number in writing.
Standard receptacle swaps — a new dedicated circuit is a bigger job ($350–$750).
Flush mounts, pendants, chandeliers — hung on existing boxes.
Estimated range
$530 – $1,100
Typical electrical project around $820
Very professional and knowledgeable. his work was very neat
Pat was the ultimate professional. He completed the work in the committed time frame.
Coastal did a great job, was efficient, courteous, and very professional. The level of service they offered was excellent in relation to the cost of the overall project. I fully plan to use them again in the future, and would certainly recommend them for your electrical needs.
Careful work and courteous, would hire again.
Very reliable on keeping the appointment, called before coming to confirm. Very pleasant and efficient in doing his job. Cleaned up after himself. We will have him do other projects for us in the near future.
