NS Builders focuses on bespoke custom homes and large renovations in Boston. The company says it was founded in 2014 by Nick Schiffer, and the Massachusetts registry lists its home improvement contractor registration as active. Six written reviews dated 2024–2025 are five-star. In January 2025, a Back Bay architect praised the team's engagement and responsiveness; an HVAC subcontractor described being on its second new-construction project with NS Builders and said the company valued its subcontractors. Those accounts speak to how the builder works with other professionals as well as the finished projects. The renovation examples are specific. In November 2024, a homeowner described combining two condos into one and praised the completion time. In July 2024, another described a three-floor, 1,500-square-foot condo gut renovation and credited the team with clear updates about timing, scope, and additional costs. An interior designer writing in June 2024 praised craftsmanship and attention to detail across repeated collaborations. The BBB profile shows an A+ grade and 11 years in business, while noting that NS Builders is not accredited; Houzz shows 5.0 stars from 33 ratings. For a custom home or substantial Boston renovation, NS Builders appears geared toward larger, design-led projects. Before signing, ask how the team will communicate schedule, scope, and change costs—the project details a past homeowner specifically praised.

I’m an architect and worked with Nick and NS on a pretty involved project in the back bay Boston. I can attest that NS is a top flight GC. Nick and his team is super engaged, excited and responsive. Quality is an absolute mission of theirs. I’m looking forward to working with them again and anyone looking for a top tier GC should give NS Builders a look.
Working with NS Builders has been an absolute dream! AGS HVAC is currently on our second new construction project with Nick and his incredible team, and we couldn’t be more impressed. The way they value their subcontractors is truly unmatched—this has been one of our best experiences in the industry. From day one, communication has been seamless. The site supervisors are rockstars—always accommodating, whether it’s providing exact locations for terminations or helping with register placement. They make the entire process so smooth and enjoyable! It’s rare to find a builder that’s not only highly skilled but also this committed to fostering collaboration across the board. Nick and his team bring a level of professionalism and fun that makes every project with them a win. If you’re looking for a builder who sets the bar high and creates a great experience, NS Builders is it!
NS Builders were fabulous to work with! We did a complete gut and remodel of two condos that we put together and we couldn't be happier with what was done, how it was done, and the timeliness of its completion! The cabinet makers within NS Builders (Materia, Ken DeCost and his team) were phenomenal!! All the cabinetry they did for us was beautiful, and all worked together and is just gorgeous. The billing system that NS used to keep us updated of what we're spending was a great help to us in terms of knowing and setting our expectations. Lastly, the sub contractors that were used were tremendous; they had the same mindset as NS employees which was wonderful!! All around, we truly believe in Nick's processes - he and the entire company are wonderful to work with and I would do it all over again with NS Builders! Here comes number 9!! I've added some photos so you can have a view into out new condo!
We were/are absolutely ecstatic with Nick's (NSB) renovation of our 3-floor 1500 sq.ft. condo gut renonation! We could not have been more pleased with the quality of design and construction, communication, and ongoing updates (timing, scope and additional costs). An additional very surprising, pleasing and unusual experience: every time we called NSB, Nick himself answered the phone. Does that ever happen? NSB was absolutely respectful of the draconian condo requirements in our building—our Facilities Manager was so completely astonished with NSB's maintaining the condo association's hallway/elevator/time requirements, so much so that he wanted NSB to do work in the common areas of the building. If a picture's "worth a thousand words" look at the before/after photos of just one feature of Nick's renovation. Thanks 1,000,0002 Roberta Radley and William Brinkley
NS Builders is top notch on both service and construction quality. I've hired them for two gut renovations and couldn't be happier with the outcome. They hire the best people, excel in design details, communicate clearly every step of the way, and deliver. Their sterling reputation is well-deserved.
