Nick Portnoy Builders is a Watertown, Massachusetts design/build and general-contracting firm run directly by owner Nick Portnoy, who describes working within roughly a 30-minute radius of his shop and personally overseeing each job rather than splitting work across separate crews. The firm's own site emphasizes fine carpentry and design-driven residential projects, from kitchen renovations to custom home builds, and HomeAdvisor's listing shows a Massachusetts HIC license, number 95634. The track record, though dated, is strong and consistent. Twenty-seven HomeAdvisor reviews from 2010 through 2015 average a perfect 5.0 stars, and the Better Business Bureau gives the company an A+ rating (it has chosen not to pursue formal accreditation). Homeowners in that period repeatedly describe Nick as personally present on site every day, communicative about problems as they came up, and careful about containing dust and cleaning up - recurring themes across reviews of kitchen renovations, bathroom remodels, and finished-basement work. A 2010 Wicked Local business note named the company 'contractor of the year.' The firm's design-oriented reputation also shows up in the press: Boston Globe, Boston Magazine (twice), and House Beautiful have featured Nick Portnoy Builders as the contractor on high-end kitchen renovations, including one that preserved an exposed-brick wall in a South End condo and another that opened up a cramped Brighton kitchen. One thing worth noting before booking: the written reviews and press coverage on file run from 2010 to 2020, so there's nothing more recent to confirm how the business operates today, and stated tenure varies slightly by source (15 years per BBB, 19 per HomeAdvisor). Still, for anyone weighing a design-forward kitchen or bath renovation in the Watertown/greater Boston area, the consistency of praise across a decade of reviews and several design-press features is a meaningful signal.

“Marcelo Vedovatto had his heart set on retaining the exposed-brick wall in the kitchen of his newly purchased South End condo, and he wanted to swap the locations of the kitchen and the dining area. Designer Karen Swanson and builder Nick Portnoy had other ideas. ... The wall was in disrepair, Portnoy recalls. “We considered replacing the damaged bricks, but it would have resulted in a patchwork effect.” Adds Swanson, owner of New England Design Works in Manchester-by-the-Sea, “Since we weren’t using upper cabinets, the bricks would have been on full display.” ...

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.
We would use their services again if we needed to.
This provider has worked on our house before, and has gotten to know the house and its quirks. We told him that we did not expect a finished basement, we just wanted one that would not be "scary". The floor was uneven and the pipe from the old and unused oil tank was showing through the concrete. There were a few rooms with walls barely still standing. We wanted to preserve the heart pine raised wood floor room, even though we didn't know its intended purpose. Our neighbor has since told us his 85 year old relative remembers playing in it as a play room, and was hoping that we didn't get rid of it. As usual, Nick came daily, even when sub-contractors were working. He always knew what they were suppose to be doing, and made sure it was done. He kept us informed of any problems or concerns he had. He was willing to use some old tiles we had for the basement sink and back splash. He even went along with my idea of tiling the wide window sill above the basement sink. Nick had the asbestos removed and sill insulated. He, and his crew, removed scary rooms, water proofed the exterior walls, put up a wall to section off the furnace from the laundry area, and put up dry wall for the laundry area. and all the other things mentioned above. Previously, both the hot water header and the dryer were vented through basement windows. This not only made the windows unusable as windows, but also caused concerns whenever the snow might cover the vents. The new vents are higher and will not be an issue with snow. We had recently begun to see some water on the basement floor. One of our neighbors had a leak in the water main to his house and we thought this might be the cause. Then the town and the neighbor's plumber came by to check out our situation and decided that the problems were with the our drains. We also had a drain specialist out to check the drains, and found that we had a whole house drain (the house is old) which needed to be changed. Even with all this done, the water issue was still there. Nick came to wait for the plumber to see what else could be the cause. He looked under the built in wooded storage benches and found that the problem was with an old pipe under the raised wood flooring going to the radiator in the play room. He had a new pipe install which circumvents around the out side of the room; so any problems will not be hidden. The new stained concrete floors look very nice and are easy to keep clean. The walls are freshly painted, and the heart pine floors and benches in the play room were sanded and stained and look great! The laundry sink and tile are perfect for the area. Going down to the basement is no longer an unpleasant experience.
We had used this contractor before, so we were fairly confident that all would go well. We were not disappointed. The bathroom is off the central hallway. We needed access to the hallway to get upstairs to the other bathroom, and this was done with no problem. A plastic zipper wall was put up to contain the dust. Nick came daily to see how the job was going, often doing some of the work himself. When he felt that the framing for the medicine cabinet was a bit too high, he had it lowered. He was able to find us more storage space as part of the shower structure. It is almost like a hidden closet. They also did a beautiful job on the woodwork and wainscoting. Nick always comes when a subcontractor is working to make sure the job is done right. He lets us know when there is any issue and the proposed solution to the issue. We have had many compliments on the bathroom, and we are very pleased with it. Nick always listens to our ideas and manages to accommodate. He has great ideas and solutions himself which have worked very well for us.
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.
