Nick Portnoy Builders has turned up in the Boston design press: a 2018 Boston Globe piece quotes Portnoy on a brick wall in disrepair, and Boston Magazine and House Beautiful describe projects Swanson worked on with Nick Portnoy Builders. The Watertown firm describes itself as a design/build general contracting and fine carpentry business run on an owner-managed model, with Nick Portnoy on every project. BBB lists him as owner and gives the business an A+, and HomeAdvisor shows 5.0 from 27 ratings and lists HIC license number 95634. The customer reviews are all from 2010 to 2015, on HomeAdvisor. The longest, from October 2013, describes a basement made usable: Nick came daily even when sub-contractors were working, had asbestos removed, waterproofed the exterior walls, sectioned off the furnace, raised the water heater and dryer vents, and tracked a water leak to an old radiator pipe under a raised wood floor. In an August 2015 review, a customer said the job started on schedule and lasted the estimated time, and a sub-contractor carried a quartzite counter up the stairs so it could go in as one large piece. A May 2012 reviewer described a new bath, a renovated powder room and a dormer finished on time and within budget, and a March 2010 kitchen customer said Nick estimated 6 weeks and was right on target. Wicked Local reported in January 2010 that the company was honored as contractor of the year.

“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. 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.
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.
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.
Nick was the general contractor and used very responsible subcontractors. He and his crew were very punctual and the project finished on time and within budget, considering the extras we added. We are very pleased with the new bath, the renovated powder room, the expansion of the landing and the window seat, and, we are thrilled with how the dormer looks outside.
