Verified record
Marroquin Electrical Services LLC is an electrical contractor based in Chelsea, Massachusetts, and its paperwork is the solid part: the state registry shows electrical licence 9035 active, held by the company itself rather than borrowed from an individual. BuildZoom lists the same number as an Electrical Business licence and names Mario Adan Marroquin as the owner, and it gives the company a BZ Score of 90. For straightforward residential electrical work around Chelsea, the licensing is in order. Before you book, get the scope and price in writing, confirm current insurance, and ask for a couple of recent customers you can call.
Typical Greater Boston range for this kind of work, from regional averages — not a quote from Marroquin Electrical Services LLC. 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.
Estimated range
$530 – $1,100
Typical electrical project around $820
