Griffin Custom Builders

Griffin Custom Builders is the name that keeps coming up on Cape Cod when a homeowner needs a full addition, a gut kitchen, or a garage turned into livable space — and it's almost always tied to one name: owner Jared Griffin, who reviewers say shows up personally on nearly every job. The volume and consistency here are hard to match: 27 written reviews from 2024 through mid-2026, every one five stars, describing a wide range of real projects. A three-bathroom overhaul came in under budget. A nonprofit in Brewster had its meeting space rebuilt to handle daily heavy use. One family worked with Jared over five years on a full home transformation, starting with hardwood floors and building toward what one reviewer called their Cape Cod oasis. Others describe additions built over garages, three-season rooms, full kitchen guts with wall removal, and a deck and patio project finished quickly without complications. A subcontractor even brought Griffin in to handle a roof, windows, siding and doors on a job they couldn't take on themselves, and called the result five-star work. The recurring themes are communication and follow-through: reviewers consistently mention Jared keeping them informed at every step, showing up when he says he will, and finishing on budget. The one exception worth knowing about: a 2024 review described a job that was supposed to start in January but didn't get underway until July — a real scheduling slip, even though that same reviewer was ultimately thrilled with the finished kitchen. Griffin holds an active Massachusetts home improvement contractor registration, verified directly with the state. BBB separately lists a construction supervisor license number for the company, with an expiration date in December 2026. The company is BBB accredited with an A+ grade. One thing worth asking about directly: the company's own website says it's been operating since 2010, while BBB's record puts its start in 2018 — worth clarifying which reflects the current business. Between the depth of praise, the range of project types, and Jared's own hands-on presence on jobs, this reads as a strong, established call for a substantial remodel or addition on Cape Cod, with the one caveat being to nail down a firm start date in writing given the one reported delay.
