A large two-story addition was the project one McNamara Construction & Design customer described in a December 2025 Google review. They said Scott and his team kept pricing and timelines from changing unexpectedly, communicated throughout the process, and took time to understand what the household wanted. The Holden business describes itself as family-owned and offers new-home construction, additions, remodeling and roofing. Its stated service area includes Holden, Auburn, Grafton, Northborough and other Massachusetts towns. A flooring job came with a tighter deadline. In a May 2025 review, a customer said Scott and his crew replaced the first-floor flooring while the family was away for a short vacation. The crew moved the furniture, removed the old flooring, installed the replacement, put the furniture back and had the dumpster collected before the family returned. The customer said the work was completed despite a snowstorm and described the price as reasonable. Outdoor projects feature in other dated accounts. A May 2025 customer wanted a deck added to an existing deck to create an entertaining space leading to an outdoor pavilion; they praised Scott’s ideas and daily presence on site. In February 2024, another household described a new composite back deck and front porch steps. A March 2024 customer said Scott built an addition to their home and praised the work and pricing. Repeat customers also described how projects were handled. One May 2025 reviewer had hired Scott twice for construction at their house and said both projects finished on time. A February 2024 reviewer said their construction work finished on time and on budget. Another May 2025 account described a full renovation of second-floor bedrooms in an old University of Massachusetts fraternity building, completed ahead of schedule. Scott A. McNamara’s Massachusetts construction supervisor licence and home improvement contractor registration are active. The Better Business Bureau lists the company with an A+ grade and without accreditation. Google showed a 5-star average from 14 ratings in August 2026.
Scott and team did an excellent job with a large, two-story addition to our home. Pricing and timelines were reasonable (and didn't change unexpectedly). Scott communicated with myself and my wife throughout the entire process, and took the time to understand our vision and executed it wonderfully.
Highly recommend. Great work
We hired McNamara Construction to help transform our outdoor space. We wanted a deck built off our existing deck to create another entertaining space leading to an outdoor pavilion. Scott had great ideas and was on the job site daily. So thankful for them helping bring our vision to life.
Scott does an exceptional job. He prices out each project appropriately and delivers on time, all while communicating clearly along the way. He can help make your visions become a reality! Highly recommend.
We have hired Scott McNamara twice to perform construction projects on our house. Both were done very well and on time! He is easy to work with and communicates well. I would definitely recommend him for your home projects, big and small.
