Gaither Bros Building Company

Gaither Bros Building Company is a Boston general contracting outfit run by Brian Gaither, whom Thumbtack lists as background-checked with 8 years in business; Thumbtack also lists a self-reported unrestricted general contractor license and a Massachusetts home improvement contractor license, though neither has been verified against the state registry. On Google the company holds a 5★ average from 11 ratings and on Thumbtack a 4.9★ from 15, and the written record — 12 reviews from 2022 into 2024 across both platforms — leans consistently toward one theme: communication. In a 2024 review, a homeowner called Brian the most responsive and communicative contractor they've ever worked with, describing frequent unprompted updates and photos during a bathroom floor renovation and a smooth handling of a mid-project scope change. In a 2023 review, a basement bathroom build-out finished within the original estimate and timeline, with steady notice throughout. The work itself ranges beyond bathrooms — a 2024 review describes upgrading two garages' rotted swing-out doors to new roll-up doors at a reasonable, no-pressure price, and other reviews cover a new porch, custom basement fixtures for an entertainment space, interior walls with sound-absorbing insulation, and a kitchen-and-bath renovation. The one thing worth confirming directly: Thumbtack's license listings are self-reported rather than independently verified, so ask to see the actual license numbers before signing. For a bathroom or basement remodel, or smaller build-outs like porches and garage doors, the reviews consistently point to a contractor who over-communicates rather than under.
