One 2022 reviewer said they'd read beforehand that a contractor could deliver quality, timeliness, or budget — but never all three — and that Timberwolf proved the warning wrong. It's a fitting line for a Billerica outfit whose reviews keep describing the same thing: homeowners who hired them once and then came back for a second, third, or fourth project over the following decade. The company, family-run by Tom and T.J. Knapp, holds an active Massachusetts home improvement contractor registration and has been BBB-accredited with an A+ grade since 2015. It also holds a Concord Historical Commission Preservation Award for its restoration of the Edward Emerson Studio — the kind of recognition that lines up with its stated focus on historical home restoration and custom millwork alongside standard residential construction management. The written reviews, running 2021 to 2023, trace that repeat-business pattern directly: one family describes two house renovations together over ten years and says they wouldn't consider working with any other builder; another recalls an extensive 2006 renovation, a finished attic afterward, and a basement gym build in 2021 — three projects, one contractor, fifteen years apart. Other jobs described include an addition combined with second-story renovations while the family lived in the house, a basement finished during the pandemic with daily check-ins and materials staged ahead of each phase, a master suite build-out, and a mix of smaller follow-up repairs — a ceiling lift installation, a leaking shower ceiling, fixture swaps — handled for an existing client rather than turned away as too small. A 2021 Boston Globe piece on a Medford home refresh, finished just before the pandemic lockdown, named Timberwolf as the builder. This is a fit for homeowners taking on an addition, a historic restoration, or a major renovation who want one team they can call again for the next project. One thing worth asking about directly: the company's own materials describe 30 years in business, while BBB's records put it at 43 years, founded in 1982 — worth clarifying if a precise history matters to you.

We had our basement finished with Timberwolf construction recently . we had a great experience working with Tom and TJ. Tom (or TJ) checked in every single day. They are very organized. Tom had all the measurements and orders done ahead of time so when it was time for a particular phase of the job to start all the materials would be readily available. They stayed on schedule as much as they could with the pandemic and coordinating with all the sub contractors involved. They have a wonderful crew as well. They treated the workspace very respectfully. Every day the crew left the space very clean & organized. They have a very skilled crew of carpenters who were able to create all the special requests we had on the project. They are flexible too when it came down to some last minute changes. We cant say enough good things about Tom & TJ and the whole crew. They went above and beyond for us. We highly recommend them!
This company is the best of the best! Efficient, very competitive prices for much higher quality work than you usually see, easy to work with, responsive…can’t say enough good things. Highly recommend and won’t be using anyone else in the future!
Timberwolf constructed an addition to our house, along with some second story renovations which were done at the same time. The crew was efficient, polite (we were living in the house during construction), and very detail oriented. The finished product is to the highest standards. We could not be happier with the results and cannot recommend Timberwolf Construction Corp. highly enough!
A huge shoutout to Timberwolf for coming in clutch once again for us! We hired Timberwolf initially to help us with some demo and reconstruction to be able to install a ceiling lift for my special needs daughter. We recently called to have several jobs in our home completed. We had a leak coming from our second floor shower that required sealing and ceiling repair. We had a toilet that was running and required the “guts” to be changed out. A vanity mirror, a hand towel holder, and crown molding that needed to be rehung and secured. Multiple other odds and ends to numerous to mention, and Roberto completed them all in a day and a half and did a fantastic job. He is very professional, timely, and courteous. He cleaned up after all his work and made sure the jobs were completed to our satisfaction. I am so grateful to the Timberwolf Team for making this process so easy! Scheduling with Jen was a breeze and super efficient. The follow up and check in from TJ was greatly appreciated. We will definitely be calling them back soon!
Timberwolf Construction helped us to create a master suite - and it is beautiful and functional. We love it! Their work was well organized with all items ordered and available before work started. Subs were scheduled to keep the project moving forward. Communication was easy and responsive. Would absolutely work with them again - and hope to soon!
