A tree came down in a storm and knocked out one homeowner's electrical service. Grid Electric was out to assess it and put an estimate together the day after the tree was cleared, then came first thing the following day to do the work — that's a January 2024 review, and speed is what these reviews come back to most. The company works out of 11 Salem Street in Medford, and its Massachusetts electrician licence, #9330, is active on the state registry. BuildZoom and Thumbtack both name Waner Da Silva as the owner; the Thumbtack profile says six years in business. The jobs it lists are residential bread and butter — outlets and switches, lighting, fans, wiring, and circuit-breaker panels. Eighteen Google reviews, every one of them five stars, run from January 2023 to July 2025, and Thumbtack shows a 5.0 from 23 ratings. Eight of the eighteen Google reviews turn on how quickly the company answered or arrived: a July 2025 customer whose disposal quit — they thought the outlet was at fault — got a prompt response and a quick fix, and a January 2024 homeowner had an outlet replaced the day after calling. Five of the eighteen mention price, calling it reasonable, competitive or fair. Two describe coming back for more work, including a March 2023 repeat customer who had recommended the company to family members. One thing to settle on the phone: BuildZoom and Thumbtack both place the business in Winchester, while its listed address is on Salem Street in Medford — check that your town is on its route. Scheduling was simple for the two reviewers who mentioned it, one of whom set the visit up with office manager Lucy in January 2024. For an outlet, a fixture, a fan or a panel that needs a licensed electrician without a long wait, this is a straightforward call. Ask what the work will cost before it starts — the pricing praise here comes from jobs done in 2023 and 2024 — and if yours is a job that ends with an inspection, a May 2023 customer described the company following the inspection with the inspector.
I had a problem with a disposal that stopped working, thought it was the outlet. I called Warner Silva, had a prompt response, and it was fixed quickly. I appreciate his professionalism and honesty. Warner is "my" electrician for every job I have going forward! Super service! A+
I was very happy …
Mr Silva is punctual, easy to schedule with office manager Lucy, professional, and does excellent electrical work. Had an outlet replaced the next day after calling and all was seamless. I found the price to be quite reasonable considering the excellent service.
A tree knocked our electrical service out during a storm. Waner and Grid Electric was out to assess the work and provide an estimate the next day after the tree was cleared and came first thing the following day to perform the work. Excellent work and responsive communication.
I had a great experience. The company was very responsive and easy to set up a visit with. The electrician was professional and fixed the issue in my kitchen quickly.
