Kneeland's work goes up, not out: dormers, second levels, third-floor additions. The company says it has been family-run out of Medford since 1984, and its Better Business Bureau file agrees, listing 21 employees under founder and president Carl Dumas, with his son Gregory heading construction. BuildZoom counts 309 permitted projects under the name. Google runs 4.5 across 44 ratings and Thumbtack 4.7 across 35, and the jobs behind them are houses that grew. A January 2025 customer listed a new foundation, a three-story side addition and an attic dormer, and called the company an honest, reliable partner from permitting through close-out. In a July 2023 review, a cape owner described the entire second floor dormered, a new bathroom added, the kitchen expanded and remodeled, and interior walls taken out with new supports put in. Four reviewers say they hired Kneeland more than once. A customer on their second addition wrote in April 2026 that both projects landed within the promised timelines at a reasonable price, and a July 2025 review covers a third-floor master bedroom with bathroom followed by a two-car garage. Project managers get named: Carl, Nick and Brian all turn up by name in separate accounts. Not everyone finished happy. A January 2023 customer, who had the roof taken off a second-floor porch to add a third-floor porch on a 2.5-family home, told everyone they knew to avoid the company at all costs and said you end up paying to have "shoddy work" fixed. A January 2022 customer set their own rating between 2.5 and 3 stars after an addition over the garage, and in a four-star July 2022 review someone who liked their project manager still advised lowering expectations on day-to-day scheduling and said the crew needed to communicate its schedule better. Medford's subreddit splits the same way. One commenter in July 2026 posted a flat "Do not use Kneeland," a day after another described a third-floor dormer plus a kitchen and bath renovation and said they did a great job and were easy to work with. For a dormer, a second story, or a room added onto an older Greater Boston house, this is the work Kneeland does most, and its Massachusetts home improvement contractor registration is active. Settle two things first: whether your town is actually covered — the company's own site lists a service area of Norwood, Wrentham, Foxborough and other towns south of Boston, while its Houzz and BuildZoom profiles name Medford, Somerville, Newton, Lexington and Needham — and how daily schedule and progress will be reported to you once the crew starts.
“Do not use Kneeland.”
“Kneeland construction, we used them for a 3rd floor dormer and kitchen/bath reno based on a recommendation from a friend, and they did a great job and were really easy to work with.”
Kneeland Construction installed a 3rd floor bathroom and dormer for me. After evaluating several vendors, they came across as the most responsive and professional, and seemed to offer the most value. When we encountered a delay due to the city, Carl was very helpful in helping to work through it. Once the project started, I worked with Nick primarily. He communicated regularly throughout the project; a trait not always found with contractors. I was very satisfied with quality of the finished bathroom. I would and plan to use them again in the future!
It is the second time I used kneeland for addition projects. like last time, things were moving smoothly and both projects were done within the promised timelines. the project managers were easy to work with and no issues at all. And their price was reasonable as well. I would re-hire them again for my future projects.
We worked with Nick from Kneeland to add a second bathroom where an unfinished closet had been and extend an existing dormer on our home. Nick was great to work with - if we ever had any questions or concerns, we could text or call him at any moment and he was quick to respond. If it wasn’t something he could address over the phone, he was great about either sending someone or coming out himself to take a look. We felt the pricing was fair for the work being done, and Nick and his team of sub contractors stayed on schedule. We’re so happy with how our new bathroom turned out, and our bedroom feels so much bigger with the dormer. It was our first major project as homeowners and we had a great experience working with Kneeland. (Included a couple photos of our in progress/after/before)

We used Kneeland to add a 2-bedroom addition on our home, which added an additional floor on part of our house. They were fantastic! They were willing to work around our funky home and were the only contractor that we spoke with that was able to keep every room in our house livable the entire time during construction! The workers were incredibly nice, prompt, and did a great job. They were very communicative the entire time. They were so nice to our toddler and became best friends with our dog! The project was completed earlier than expected and was exactly on budget. We would highly recommend them!
