Verified record
Christopher P Barthuly works out of 28 Marshall St in Winthrop, and the thing a homeowner needs to settle first sits in the licensing line rather than the workmanship line: BuildZoom lists his Newton electrician licence #53822 as having expired on 31 July 2019, and says it confirmed the licence was still expired when it checked in March 2022. BuildZoom zeroes out its own score for him on that basis. The permit trail behind him is specific, though. BuildZoom's database credits him with 36 permitted jobs, and they cluster hard around one kind of work — wiring and installing cooling: ductless mini-splits, condensers, air handlers and heat pumps, plus the service and panel upgrades those installs need. The addresses run across Greater Boston and both shores, but nearly all of them were pulled in 2017 and 2018; only one has landed since 2024. BuildZoom hasn't collected a single customer review for him. Electrical work in Massachusetts requires a current licence, so that is the first call: ask him directly for his licence number and check its standing with the state before anything is scheduled. If it has been renewed, the permit history points to a lot of heat-pump and mini-split experience. If it hasn't, that is where the conversation ends.
Typical Greater Boston range for this kind of work, from regional averages — not a quote from Christopher P Barthuly. 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.
