Colleary Construction is a Belmont, MA general contractor founded and run by Dara Colleary, a Massachusetts Civil Engineer EIT with a structural engineering degree who the company says has worked in commercial and residential construction for more than 25 years. Its Massachusetts home improvement contractor registration is active, verified against the state registry, and it holds an A+ Better Business Bureau grade. Nineteen reviews from 2023 through 2026 run a clean five stars, and the same details recur across very different jobs — a finished second floor built into a garage, a full addition, a gut rehab of a two-family home that included pouring a new basement floor and installing a French drain while keeping the home heated and livable, and an exterior facelift on a 1950s multi-family that stayed on budget and schedule. Reviewers consistently credit Dara himself with fast, direct communication (one said he replied to messages within seconds, even during off hours), careful attention to detail, and clear proposals with realistic timelines. A 2024 review described a harder situation: the homeowner had already paid another contractor who took the money and abandoned the project partway through, and hired Colleary to pick it up from the halfway point. The company's self-reported credentials line up with that engineering background — LEED AP, OSHA 30 certification, and membership in a regional professional remodeling organization — though these weren't independently verified here. For a homeowner planning an addition, a full renovation, or a project with real structural or drainage complexity, the depth and consistency of this record — a single named owner across every review, verifiable licensing, and jobs that match what the reviews describe — make this a strong option. The one caution worth noting is volume: with one employee on record and a young company (incorporated in 2023), it's worth confirming current availability and timeline for a larger project.
Flawless execution from an amazing team! If you are looking for a contractor who is honest, highly organized, and delivers with great precision and care, hire Colleary Construction. They kept our project completely on time and were incredibly responsive. Their attention to detail is remarkable. Every single team member from all the different disciplines (carpentry, plumbing, electrical, etc.) was pleasant, respectful, and a joy to have on our property. If you want a timely, low-stress, and meticulously executed project, I cannot recommend them enough!
Dara and his crew were exceptional! I would not hesitate to hire them for another job in the future. They created a finished room in our garage by building a second floor. Dara was excellent with communication and resolving any questions or changes/additions we requested. His crew were detail oriented in their job, they showed pride in their work, and were always friendly, courteous, and respectful.
Colleary Construction sets the standard for professionalism, attention to detail and craftsmanship. Dara was highly attentive to the project and ensured that we were consistently on the same page in terms of renovation goals and benchmarks. He was consistently available and communicative about project updates and construction progress. He provided excellent documentation to make sure there were no misunderstandings. Importantly, he was patient and solution-focused with the changes in the project as our renovation scope evolved over time. His whole team was similarly amiable, professional and capable of working through unexpected issues. Overall, Colleary Construction did a superb job and I am looking forward to working with them again.
We can’t say enough good things about our experience with Colleary Construction! Since this was our first major home renovation, we were definitely a bit overwhelmed and unsure of what to expect.From the very beginning, Dara and his team made the entire process feel stress-free and manageable. His team is friendly, hardworking, thoughtful, punctual, and incredibly meticulous with every detail. There was always someone working on site, and either a project manager or Dara himself consistently checked in, which gave us so much peace of mind. As a result, our kitchen, bathroom, and mudroom turned out beautifully—and the project was completed on time! Most importantly, communication was always open and seamless. Dara worked wonderfully with the other vendors we used and was always available to jump on a phone call, answer a text, or stop by to check on something—no question was ever too small (including how to turn our disposal back on!). He’s a great problem solver and, above all, a genuinely wonderful person who truly cares about his work and the people he works with. We definitely plan on using Colleary Construction again for future home renovation projects!
I can't say enough good things about Colleary! We worked with them our first time this past fall to help repair our porch and everything turned out so much better than we expected. Working with Dara was easy and the crew was clean respectful and nice. The craftsmanship of all the work is top-grade. The thing that impressed us the most is that they went above and beyond in many areas just seeing that something needed to get done and took care of it without us haggling on each small thing. Would HIGHLY recommend!
