Manny Melkonyan runs Boston Building Concepts out of Watertown, and the reviews describe someone who takes on real complexity: full home additions, whole-house renovations after a burst pipe, and gut renovations of multi-bedroom homes, not just single-room updates. Twenty-one of the 22 reviews on file, spanning 2021 through mid-2026, are five stars, and they describe the same habits again and again: clear estimates, staying on budget and schedule, and Manny personally staying in communication throughout. A 2022 review describes a full second-floor addition with three bedrooms and a bathroom that took over a year, with Manny available and communicative the whole way; a 2025 review describes replacing two rotting decks with composite ones after finding water damage under the old sealant. Multiple customers who are architects or who bid the job to several companies first say Boston Building Concepts still stood out. One March 2026 review is a clear exception: the customer says communication and attention to detail were strong at first but declined as the project went on, with issues they say should never have happened. Reviews both before and after that one, including as recently as June 2026, describe the same organized, communicative process as the rest of the record — so it's worth asking current or recent customers directly about consistency on a longer project. Manny's Massachusetts Construction Supervisor license (CS-104829) is active, verified against the state registry. For a bathroom remodel, an addition, or a larger renovation, this is a contractor with real experience on complex jobs — ask specifically how he handles communication and oversight if your project runs long.

We hired Boston Building Concepts for a kitchen and bath remodel in one apartment of a two family home in Watertown. It was a good experience. The estimate was clear to understand. We met on site and Manny answered our questions. It wasn't the highest or lowest bid. Manny was responsive to calls and texts. He even drove over to receive an after hour plumbing delivery which was very helpful. He worked well with the cabinet shop and problem solved our cooktop ventilation problem. We were able to coordinate subcontractors and tenants without too much trouble; for example: we upgraded the electrical service from 200 to 400 amps and this required power to be shut off for the upstairs tenant too. That was a necessary inconvenience but Manny worked to accommodate all parties. I appreciated Manny's efforts and would definitely use Boston Building Concepts again.
When we first hired Manny communication was great and he seemed easy to work with but as the project went on the quality and attention to detail declined significantly. Manny stopped proactively updating and communicating with us and we repeatedly found issues that should never have been overlooked. There were multiple examples of poor workmanship and avoidable mistakes. His team did not properly protect our newly refinished hardwood floors- putting down no protective materials and operating construction equipment like tile saws directly on the floors causing noticeable damage. While he ultimately paid to have the floors repaired, it was frustrating and never should have happened with a professional crew. Manny also scheduled the floor repair the day before our known move in date and did not communicate that we would not be able to move furniture in the next day causing a logistical nightmare when we showed up with the professional movers. We also had an issue with the electrical work: we clearly communicated where an outlet needed to be centered and the electrician marked the wrong spot. We caught this before the outlet was installed and Manny assured us he would make sure it was installed in the correct place. This was ultimately installed in the wrong location and he tried to charge us to move it even though it was his subcontractors error. Another example is in our bathroom where he never actually attached the backsplash- he just left it resting on the counter completely unsecured where it easily could be knocked over. The cabinet work was similar. Just one month after our new cabinets were installed one of the side panels fell off. It looks like this was attached with some cheap foam adhesive and not properly secured. The cherry on top occurred one week after we moved in (and had already paid the final invoice in full) when Manny let us know he'd be arriving with the building inspector the next morning. We had no idea he had not completed the final inspection as this was never communicated to us. When they arrived the building permit had been lost during move in which complicated the final sign off. While Manny did ultimately pay for the floor repair and gave us a small credit back for the inconveniences caused the overall pattern of poor communication, lack of attention to detail, and repeated avoidable mistakes made this renovation far more stressful than it needed to be. I would not recommend Manny/Boston Building Concepts. Edit [3/30/2026]: We’ve now been in our home for four months and continue to uncover additional issues with Manny’s work. Construction debris was left in the backyard after the job was supposedly complete. Cabinet side panels are still falling off due to poor-quality adhesive. Most recently, we discovered that the drain/strainer we provided for our kitchen sink was never installed. Instead, Manny’s team installed a different strainer, which has already broken and does not fit properly. When I asked about this, I was told they “couldn’t find” the one I provided (it was in the same box as the sink) and chose to install a “better” alternative without contacting me. I do not agree with that decision, and I should have been consulted before any substitution was made. We have since located the original strainer we purchased—it had been left in the back of the sink cabinet behind the pipes—and now need to hire someone else to correct the issue. If you value clear communication, attention to detail, and accountability, Manny is not the right fit.
We recently hired Boston Building Concepts for a bathroom remodel in Watertown, MA, and honestly, the whole experience exceeded our expectations. From the first consultation, they were professional, responsive, and genuinely listened to what we wanted. They helped us refine our ideas without pushing unnecessary upgrades, which we really appreciated. The quality of the work is outstanding. The tile installation is precise, the fixtures are perfectly aligned, and everything feels solid and thoughtfully finished. They kept the job site clean and organized, and the project stayed on schedule with clear communication throughout. What stood out most was their attention to detail and problem-solving. Anytime a small issue came up, they handled it quickly and confidently. Our new bathroom looks modern, functional, and beautifully done. We’d absolutely recommend them to anyone looking for a reliable and high-quality general contractor.
