Its Massachusetts home improvement contractor registration, number 195621, is active on the state registry, with Jared Griffin as the holder of record. A recent customer said they did a full basement and could not be happier with the outcome. A 2025 customer wrote that Jared converted a one car garage plus a 12 ft addition into a family room, office, half bathroom, storage closet and a new deck, started and finished on schedule and budget. That 2025 customer also said he sent updates on the progress, including photos and videos, at least once a week. A 2025 reviewer writing for a Brewster nonprofit said Jared did the first-floor work on its building in less than three months, and that the group hired him again to replace the roof, all of the siding and trim. A 2025 customer hired the company to install all new windows and said the windows arrived on time. A 2024 customer said Jared coordinated multiple subcontractors on a kitchen gut and remodel and dealt with all the inspectors. A 2024 customer said a kitchen job that was supposed to start in January did not start until July.

Jared and his entire team are amazing to work with. They show up when they say they will and are very focused on every detail of the project. We did a full basement and could not be happier with the outcome. I highly recommend them as custom builders.
Jared was absolutely top tier !!! He did 3 bathrooms in my home. He not only delivered by blowing my visions out of the park but he did it under a BUDGET! Highly recommend Griffin Custom Builders for any new construction or project you have ! 10/10
I absolutely love working for Jared Griffin and the team at Griffin Custom Building. They make every project a pleasure with their professionalism and attention to detail. It’s always a fantastic experience, and I can highly recommend them to anyone looking for top-notch building services.
We are a Not for profit organization in Brewster. Three years ago, we purchased a building that needed major renovations on the inside to facilitate meeting spaces. The building is used seven days a week and needed to handle large groups of people every day. Jared worked with us in the design of the first floor and did the work in less than three months. We hired him again last year to replace the roof, all of the siding and trim. We highly recommend J. Griffin Builders! Joanne Wisniewski President Pause A While
Griffin Custom Builders started with the remodeling of our old kitchen and did a terrific job.Everything came out perfectly as planned. We then decided to add a master bedroom suite over the existing garage. Again, Jared and his crew did a fabulous job from planning, permitting and putting on the final touches. Everything was done at top quality and at reasonable prices. Thank you Griffin Custom Builders. Peter F W Yarmouth
