Nick Portnoy Builders LLC is a Watertown, Massachusetts design/build and general-contracting firm focused on design-driven residential construction, kitchen renovations, custom homes, and fine carpentry. The company describes an owner-managed model in which Nick Portnoy provides personal attention, design input, and quality control, working primarily within about a 30-minute drive of Watertown. Homeowners describe careful design ideas, clear problem solving, attention to detail, dependable crews, and high-quality carpentry. Older HomeAdvisor accounts from 2010 through 2015 include a basement project for a seven-unit condominium and other renovation work, while a 2022 account reports a professional team that completed a renovation on time. A 2025 project mention describes a challenging house lift. Before booking, confirm current licensing and the exact scope, budget, and schedule. The public record is strongest for older residential renovation accounts, and the company's own process says projects operate on a cost-plus basis with limited concurrent projects. Nick Portnoy Builders is a good fit for homeowners seeking hands-on design/build or general contracting for a substantial residential renovation or custom build. Ask for current references, a detailed cost-plus proposal, and the applicable permit and license details.

Our experience with Nick Portnoy Builders was excellent and we recommend this pro.
Our experience with Nick Portnoy was excellent. He had terrific design ideas right from the start. During the project, if a problem popped up (as they always do), he offered efficient and clear solutions. The work was started on schedule. The job lasted for the estimated amount of time. Nick and his crew did a great job protecting the good parts of our apartment and sealing off dust from others. Nick works with a group of sub-contractors who we found helpful and responsive. The quartzite counter has been a big hit. The sub-contractor picked out the stone for us, cut it nicely, and installed it very well. He even carried up four flights of stairs so it could be installed as one large piece rather than cut it to fit in the elevator.
He is excellent and he did a really beautiful job. He had a good price and the work was beautiful. He is a very good carpenter. The people that work for him are very responsible and respectful. They showed up every day and they were a pleasure to have around. He is very busy but we would hire him again.
I have nothing but great things to say about Nick and his team. After having interviewed a few contractors, I picked Nick because of the clear attention to detail he would bring to the job. He took copious notes and asked a lot of questions during the initial conversation. The budget and contract he drew up were clear and detailed. Nick completed things on time, and the budget was what Nick said it was going to be at the beginning. Nick responded to communications promptly, and whenever we hit the inevitable snag, Nick took the burden upon himself and left me stress-free. They were very comfortable working with the parking and space restrictions within central Boston, and they communicated respectfully with my neighbors. Last, but not least, the work they did was beautiful. I look forward to working with Nick and his team again.
Nick's company started the work for us in the summer of 2010 and continued to do additional walls as our 7-unit condo had funds for the work. He was affordable, professional, and our basement was never cleaner than after the crew cleaned up for the day. Our Town Inspector told me he wished more people in town used Portnoy Builders because of the quality of his work and the ease of working with Nick. He is trustworthy, fair in price, prompt, reliable - a gem of a company.
