Greater Boston Contractors is a Brookline general contractor whose basement finishing work runs through dozens of five-star Google and Thumbtack reviews — full basements with a bathroom, family rooms, and home offices, plus drainage and sump-pump work, come up again and again, with reviewers singling out co-owners Wellynson de Oliveira and Alyson Hoepers for staying hands-on through permits and inspections. Kitchen and bathroom remodels, drywall installation, and hardwood floor refinishing round out the work. The company holds an active MA HIC license (213686). Thumbtack lists Top Pro status for 2022, 2024, and 2025. The company says it has served the Greater Boston area for 15 years and offers free estimates.
The kitchen remodel turned out great.
Very happy with our basement remodel / finish, Allyson who helped manage the project was a pleasure to work with, maximized the space we had!
Had a variety of needs after water damage from ice dams, including rebuilding ceilings and a floor, painting, and some electrical work; says they did a great job with all of it.
Excellent work, very professional. Hired GBC to finish a basement and add a full bathroom; delivered high-quality work at a reasonable price, was flexible with change requests, communicated well throughout, handled permits/paperwork transparently, and finished on time. Praised project manager Allyson specifically. Highly recommends them for basement finishing, bathroom additions, or home renovation.
We hired GBC in 2025 to renovate our basement and they did a great job, I'd recommend them to anyone.
