Verified record
Harbor Electrical Construction is a Chelsea, Massachusetts electrical contractor, listed on BuildZoom for electrical work. The state registry carries Massachusetts electrician licence #5863 under the company's name and shows that licence expired; BuildZoom lists the same number with a 2007 expiration date. That makes the licence the first thing to sort out. Ask who would hold the active Massachusetts electrical licence for your job, get a certificate of insurance, and have the scope and price in writing before any work starts.
