- Same-day emergency fixes — fixed a dead dryer outlet in one visit

- Pricing unconfirmed — sole reviewer on cost had no comparison point
- License status unverified — BuildZoom's active claim is self-reported, not registry-checked
Joe Slowey runs Lumen Electrical Systems out of Carver, on the South Shore, and the spread of jobs in the reviews says a lot about who calls him: homeowners mid-addition who need a panel bumped up to code, and people wiring smart lighting into an older house. A few directories list the same operation under a related name — Jvs Electric, or Joseph V. Slowey Electrician — same owner, same crew. The last six months tell the clearest story: eight reviews, all five stars, none of them thin, on top of a Google page that already averages 4.8 from twenty ratings. In June, a homeowner had the team wire an entire addition and upgrade the service from 100 amps to 200 amps, and singled Joe's crew out as the best of the several subcontractors on site — they introduced themselves on arrival, reported progress daily, and cleaned up before leaving, which the reviewer noted wasn't the norm with the others on the job. In February, a call about a dead dryer outlet got a same-day fix from a technician named Cam, handled fast enough that the reviewer wrote in specifically to thank both him and Joe. Earlier reviews going back to 2023 tell a similar story across Google and two outside directories — on-time crews and clean work — so this isn't a new operation riding a hot streak; it's a multi-year pattern. Before calling, get a number in writing. The one reviewer who brought up cost at all said flatly they had no other electrical work to compare it against, so nothing here pins down what a job should run. It's also worth knowing that a BuildZoom listing scores it 90 out of 100 and marks the license as "Not Required" and active — that's BuildZoom's own self-reported check, not a state registry confirmation. For a service upgrade tied to a renovation, or smart-home lighting work, Slowey's crew has a clean multi-year record behind it. Get a written estimate before booking, since none of the reviews establish what typical jobs cost.

Joe and his team did all the electrical in our addition as well as a service upgrade from 100 amps to 200 amps. All of his employees were great to work with. We had numerous subcontractors at our house during the addition process. Joe and his team were BY FAR the best of all of them. They made sure to introduce themselves on arrival, kept us informed during the day on progress and cleaned up when they were done. We found that these 'little things' were not the norm with most other subcontractors we dealt with on this project. We highly recommend using Lumen Electrical Systems and we will be using them again when the need arises.

Great experience working with Lumen Electric. Joe Slowly, owner, always answers emails, texts, phone calls in a timely manner. The crews arrive on time and are very professional, polite, explain when necessary, and clean up. Additionally all work is top-grade. Not sure about the cost as I have not had a significant amount of electric work to base an opinion.
