Verified record
Whelan Denehy is an electrical contractor based in Canton, Massachusetts, carrying a BuildZoom Score of 92, the directory's own ranking for licensed contractors in the state. BuildZoom's profile shows two completed projects on file and attaches an Electrician license, a Master Electrician license, and a Plumber license — all filed under the same number, 12655 — to the company. The Master Electrician and Plumber entries haven't been reconfirmed recently: the master license shows an expiration date from 2016, and the plumber license is listed as inactive, cancelled at some point. There isn't a customer review to point to on any platform tied to this business, so its track record on actual jobs is still unwritten. Anyone considering Whelan Denehy for electrical work would do well to ask directly about current license status and for references from recent jobs, since a directory profile is what's available right now rather than verified state records or a history of customer accounts.

Standard receptacle swaps — a new dedicated circuit is a bigger job ($350–$750).
Flush mounts, pendants, chandeliers — hung on existing boxes.
