Greater Boston Contractors

Greater Boston Contractors is a Brookline outfit that homeowners increasingly know by two names: the company, and Wellynson, who reviewers describe running estimates, sitting through project planning, and personally checking in throughout the build. Its Massachusetts home improvement contractor license is active, and Thumbtack lists it as Top Pro in 2022, 2024, and 2025, with a background-checked owner and 10 years in business. Basement finishing is where most of the record lives — full build-outs with media rooms, home offices, playrooms, bars, gyms, and added full bathrooms, several running 1,000+ square feet across two phases. Recent reviews from spring and summer 2026 describe a kitchen remodel and a basement finish where project manager Allyson "maximized the space" available; earlier accounts go deeper — a 2024 review described a roughly 1,400-square-foot basement converted into a media area, full bar, bathroom, gym, and storage, and a 2025 review described a two-phase, 400-square-foot-per-phase Lakeville build — after vetting several contractors first — that ran from permit application through final inspection, naming crew members Matthew Santana, Alyson Hoepers, and Ramon. Bathroom work is the other consistent thread: a 2024 review described replacing three bathrooms in one house that drew a "wow" from the homeowners' friends, and a 2025 review paired a detailed, transparent estimate with tiling and fixture work praised for precision. The one recurring snag, echoed both on Google and in Thumbtack's own summary of its reviews, is inconsistent project-manager coordination — a couple of otherwise-satisfied reviewers had to repeat instructions to different managers overseeing the same job at different points. Worth asking who the single point of contact will be before signing on for a larger project.
