A Tesla charger in the garage, a well-defined quote and a work area left spotless: that is the job a May 2026 Google reviewer described from G&S Electric, adding that it was their second time using the company. G&S Electric LLC is a Cohasset electrical business. Its BBB profile lists Brian J. Galvin as owner, one employee and a start date of 9/11/2019, along with residential wiring, commercial installations and energy-efficient technologies among its services. The Massachusetts electrician licence 10747-EL-B is active, with Brian J Galvin as holder of record. BBB grades the company A+. One BBB review complains that the phone number listed for the business reached a person who said it was the wrong number and had never heard of G and S Electric.
Used G&S to install Tesla charger in my garage. They had a well defined and well priced quote. The work by the team was exceptional and they left the work area spotless. I have used them 2x now and would use them again for sure. Would strongly recommend them for your electrical needs both small and large.
I called the number and double checked their site and here because I needed an electrician for a panel upgrade and the person that answered said it was the wrong number and that he never heard of G and S Electric even though the phone number was updated here in March and the website showing the number said 2024.

Typical Greater Boston range for this kind of work, from regional averages — not a quote from G&S 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.
