Verified record
Allied Builders Group is a Watertown, MA general contractor that has been building additions, remodeling bathrooms, and handling a wide range of home-improvement work — the company's directory listings add roofing, siding, windows, painting and flooring to the mix. Angi lists a Massachusetts trade license (CS-121149, expiring in 2028) for the company, though that number comes from the directory rather than a state registry verification. Every written review on file, spanning 2017 through 2025, is five stars, and several point to the same project manager, Marc, by name. In a 2025 review, a homeowner called their home-addition project exceptional from the initial consultation through the final touches. A 2024 review describes something more pointed: the company stepped in after a homeowner's original contractor disappeared mid-bathroom-repair, having already collected a $2,000 advance on a $3,600 job, and finished the work. Another 2024 review credits the team with finishing on schedule at a cost that matched the original quote exactly — no surprises at the end. Older reviews from 2017 describe the same pattern: on-schedule work and competitive pricing. On the platforms themselves, Allied holds a 5.0-star rating on Angi from 19 reviews and a 5.0 on HomeAdvisor from 2 reviews. The two directories report different self-reported tenure — 32 years on Angi, 38 on HomeAdvisor — a minor inconsistency worth noting but not a red flag on its own. Only seven written reviews are on file here, and the trade license hasn't been checked against the state registry directly, so it's worth confirming the license number is current before signing anything. For an addition, a bathroom project, or a general remodel — especially one where reliability and hitting the quoted number matter — the reviews describe a contractor that shows up, finishes on time, and stands behind the price it quoted.
Typical Greater Boston range for this kind of work, from regional averages — not a quote from Allied Builders Group. Use it to sanity-check bids, then get the real number in writing.

We recently had to deal with a challenging situation when our original contractor disappeared after doing only a minimal amount of work on our bathroom repair. We had already paid him an advance of $2000 from the total $3600 agreed upon, and we were left in a tough spot. Thankfully, we found Marc Silva of Allied Builders Group, who came in and truly saved the day. From the moment Marc arrived, he assessed the incomplete work and quickly put together a plan to finish the job efficiently and to a high standard. His professionalism and expertise were evident throughout the entire process. Allied Builders Group not only completed the work on time but also exceeded our expectations with the quality of their work and we are very happy with the results We highly recommend Allied Builders Group for any home renovation projects. Their reliability, skill, and excellent customer service made a difficult situation much easier to handle. Thank you, Marc, for turning our bathroom repair into a success story.
