Elias Constantinou Construction

Elias Constantinou Construction works out of 1603 Centre St in Littleton, and what is solid about it is the paperwork rather than the praise: its Massachusetts home improvement contractor registration is active, held in Elias Constantinou's own name. BuildZoom counts 16 permitted projects behind the company and separately lists a Massachusetts construction supervisor licence, #CS-082400, which it says it checked in July 2026. That second one is the directory's claim, not something confirmed against the state, so treat it as a lead to verify rather than a fact. The part homeowners usually lean on is simply not there. No customer has written about this company anywhere — no stars, no account of how the crew schedules, communicates, or handles a problem discovered mid-job. A permit count tells you they build; it says nothing about what hiring them feels like. Worth putting in a bid comparison, particularly for permitted structural work where a construction supervisor licence is the relevant credential. Before you sign, ask for two or three recent local references you can actually drive past, and confirm both the registration and the supervisor licence yourself with the state.
