Trevor Kelly Construction Services works two ways: it supplies carpentry labour to general contractors around Greater Boston, and it takes on residential work of its own. The Wilmington company describes itself as a full-service carpentry outfit with over 20 years in residential and commercial construction, covering a 33-town area across the Merrimack Valley and north of Boston. Its Houzz page runs to 10 project galleries and lists the design-build side of the work — home remodels, additions and extensions, kitchens and baths, decks, outdoor kitchens and custom homes. BuildZoom lists a Massachusetts construction supervisor licence, CS-108070, two home improvement contractor registrations, #180585 and #182397, and a Rhode Island residential contractor number, #43212. One thing to sort out early: Houzz gives the address as 26 Saint Paul Street in Wilmington, while an unclaimed Procore page for the same company and phone number gives 50 Garden Ave. This is a sensible call if you want a carpenter used to framing and finish work on a builder's schedule — an addition, a deck, a kitchen. Ask to walk through the Houzz galleries closest to your own job, ask whether his crew runs the project or a general contractor does, and check the construction supervisor licence and the home improvement registrations on the state's register before you sign.
