1620 Builders, Inc.

1620 Builders is a Plymouth general contractor run by Jonathan McKinney, working residential and commercial jobs across the South Shore, Cape Cod and the Islands. The clearest sense of scale in the record: in a 2022 review, a family described hiring the company to gut, expand and rebuild a 1950s beach house into their full-time home — a large project made harder by pandemic-era supply-chain and subcontractor shortages, which the reviewer said the crew navigated without losing its footing. Basement work shows up repeatedly. A 2023 review describes a full lower-level build-out — bedroom, family room, full bath, exercise area and workroom — and a 2025 review credits a team member named Mike with finishing a separate basement renovation on time and within budget. In a 2024 review, an architect who hired the company for work on their own home — a new basement bathroom, an exterior deck and window replacements — singled out care given to details "closed up within walls," along with fair, transparent pricing. More recent jobs include a kitchen renovation and flooring project (early 2026) and a sunroom addition (late 2025), both described as finished on budget despite some hiccups along the way. The company also holds an A+ Better Business Bureau rating with nine years in business, a Houzz badge, and Plymouth Chamber of Commerce membership. The record isn't unblemished: a 2022 review described a home remodel in East Bridgewater where a load-bearing beam installation was followed by a crack across the ceiling below it, and the reviewer said calls and messages afterward went unreturned. For a whole-house rebuild, basement finish, or kitchen project on the South Shore, this is a contractor with a real multi-year track record and named staff customers return to. Given the one unresolved-sounding complaint, it's worth asking directly how they handle callbacks on structural issues after a project wraps.
