Verified record
John V. Roy is an electrical contractor listed in Rockland, and the BuildZoom profile for the business names Cristiano Da Silva as its owner. What BuildZoom carries is a permit trail and a licence block. The permits are a pair from 2013 — one building, one electrical — for a kitchen and bathroom remodel at a house on James Avenue in Nahant, alongside one sample project and a BZ Score of 90. The licence block lists several Massachusetts numbers tied to the name: an electrical business licence #8400, plumber and master plumber numbers, and a sheet metal licence #4922. For electrical work at a house, the useful first call is a direct one: ask which licence the person doing your job holds, and for a recent job like yours you can look at.

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