T.M. Sullivan Construction

T.M. Sullivan Construction is a small, fixed-cost general contracting outfit in Norwell that only takes on a handful of projects a year — closer to a boutique operation than a high-volume renovator. Owner Tom Sullivan, who the company says holds a construction management degree from UMass Amherst and worked at Shawmut Design and Construction and Bond Brothers before striking out on his own, runs it with Nicole Sullivan; BuildZoom shows the pair permitting 25 projects since 2016, mostly home additions and kitchen and bathroom remodels in Hingham and Norwell, with permits typically running around $179,000 — serious, higher-end residential work rather than small repairs. Massachusetts's home improvement contractor registry shows its license, #181051, active and held directly by T.M. Sullivan Construction LLC. BuildZoom also places the firm in the top 5% of the state's 139,240 licensed contractors by its own scoring, and the BBB rates it A+, though it isn't accredited and shows no filed reviews or complaints. The written reviews on file are dated — the newest from 2021 — but consistent: in a 2015 review, a Houzz customer described a third-floor renovation finished exactly as quoted; in a 2019 review, a homeowner called a slider-and-deck installation outstanding and ahead of schedule; a 2024 Reddit post credited the firm with essentially rebuilding a home through a series of unexpected complications while keeping the facade's period details intact. Given the fixed-cost, few-projects-a-year model, the practical thing to nail down before signing on is scheduling — availability for a company this selective is likely the real constraint, more than the quality of the work itself.
