Verified record
Typical Greater Boston range for this kind of work, from regional averages — not a quote from Chappy Corporation. 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.

Sixty years in, and the trail Chappy Corporation leaves is in permits and federal jobs, not in customer reviews. The Chelsea company was started in 1966 and incorporated that December, and its BBB profile puts it at 41 employees doing electrical systems plus general building construction, alarm and fire-protection sprinkler systems, pumping stations, sewage and water treatment plants and telecommunications work. The outside references match that institutional book of business: CommTank described working as a subcontractor to Chappy on an FAA project at Logan Airport, upgrading underground fuel lines and relocating monitoring equipment for the emergency generator system. Further back, the Bowling Green Daily News reported that in December 2004 OSHA, the National Park Service and the Chappy Corporation signed a worker safety and health partnership agreement at the start of Mammoth Cave's underground electrical renovation. The homeowner-facing picture is thinner and less flattering. Google shows 3 stars from two ratings and no written comments. BBB does not accredit the company and marks it Not Rated, saying it lacks sufficient information to issue one. BuildZoom's unclaimed page carries a score of 0 under the flag "No active license on file": it lists a Massachusetts master electrician licence #5857 last verified with a July 2016 expiration date, and separately shows a City of Newton electrical licence, a Virginia electrical and highway/heavy licence and a Massachusetts Department of Public Safety S-Licence as inactive or at one point cancelled. Those are that directory's records, not a state registry check. One more thing to weigh before calling: safetyrecord.org reports one OSHA inspection of The Chappy Corporation since February 11, 2025, resulting in one violation and $3,476 in penalties on record. Even who runs it reads differently depending on the page — BBB lists Michael Massimino as president while the older text on that same profile still names Charles E. Colbert. For a commercial or institutional job this is a long-established shop with a real project history behind it. Before signing anything, confirm the current licence status directly with the Massachusetts Board of State Examiners of Electricians and ask what the 2025 inspection was about.
