## The honest read

John Vespa Electrical Contractor LLC carries a verified Massachusetts electrician license under John Vespa himself, an A+ BBB rating, and a 5★ average across 94 Google ratings — the kind of stacked verification that's rare in this trade. The company runs as a family operation: reviews describe John working alongside his sons Dan and Phil, plus longtime staff Eric, Tim, and Shane.

Panel and service upgrades are a recurring specialty. One recent review describes a 150-amp service upgraded to 400 amps with two new 200-amp smart panels plus a 100-amp panel for a building's common area. In a 2023 review, a condo association describes coordinating a 400-amp electrification upgrade across three families — the review credits John with spending an hour walking through the building's five-year electrification plan before quoting.

Knob-and-tube removal and full rewires in older homes come up repeatedly: a 2022 review describes a full attic-to-basement rewire that preserved irreplaceable antique wallpaper by cutting only small openings for new outlets, and a 2023 review describes upgrading half a house from its original knob-and-tube wiring. A 2026 review describes five years of work on an 1890s house, crediting the team with understanding old-house construction and preserving its architectural character.

More than one review compares Vespa favorably against competing quotes: a 2025 review describes them avoiding 8–10 holes in drywall that a competing contractor had planned to cut for a minisplit install, instead routing the wire under the floor, and a 2024 review describes a wood-shop wiring job finished in half a day when other contractors had quoted a week.

The one blemish on file is a single 2022 Reddit comment describing a customer who couldn't reach the company by phone or email on their last attempt, after years of prior use — an isolated account against an otherwise deep and consistent record.

For panel upgrades, knob-and-tube removal, or electrical work in an older home, John Vespa Electrical has a verified license and a long, well-documented track record to back it up.

**Strengths:**
- Panel & service upgrades — full 400A upgrades with smart panels completed
- Knob-and-tube removal — full rewires done with minimal wall damage
- Beats competing quotes — faster timelines, less demolition than rivals
- Verified & accredited — active MA license and an A+ BBB rating

**Concerns:**
- Isolated contact gap — a 2022 account describes trouble reaching the office once
