# 1620 Builders, Inc. **Trade:** Kitchen Remodel · **Address:** 12 Cedarhill Park Dr #4, Plymouth, MA 02360, USA · **Phone:** (508) 682-1620 · **Website:** http://www.1620builders.com/ · **Languages:** English **Rating: 3.8/5** (medium confidence) — from 13 reviews across 7 sources. A 0–5 star rating built from what customers and the public say (every review and mention weighted by where it was posted, how old, how detailed and how credible it is, shrunk toward a 3.5★ baseline when evidence is thin) plus what the record shows (Reddit recommendations or warnings, a registry-verified licence, how recently they were reviewed, customer work photos, BBB grade, negative news, a revoked licence). Positive record counts only as far as the reviews have earned it; penalties count in full. Confidence describes how much weighted evidence stands behind the number, never the number itself: low when fewer than about five normal reviews' worth of weight (or mentions only) support it, medium up to about twenty, high beyond that across at least two sources. An operator flag for a suspicious review pattern caps a rating at 3.5★ and marks it low. 92% of sentiment-scored reviews read net-positive. Last 6 months: 0 reviews, 0 negative. ## The honest read 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. **Strengths:** - Whole-house rebuilds — gutted and rebuilt a 1950s beach house - Basement finishes — bedrooms, baths and family rooms built out - Transparent pricing — architect praised no-surprise billing on own home **Concerns:** - 2022 complaint — beam install crack, calls went unreturned ## Claims & citations Every claim below is backed by real evidence rows — uncited claims are dropped in code before publication. - A 2022 review described a load-bearing beam installation followed by a crack across the ceiling below it, with calls and messages afterward never returned _(confidence: medium)_ - [Google Reviews](https://www.google.com/maps/reviews/data=!4m8!14m7!1m6!2m5!1sChZDSUhNMG9nS0VJQ0FnSUMtbnRtT0xREAE!2m1!1s0x0:0x2b4363064a594b9c!3m1!1s2@1:CIHM0ogKEICAgIC-ntmOLQ%7C%7C?hl=en) — “1★ Did good work, but if something goes wrong or needs to be fixed don’t expect them to come back to fix it or even return your calls.
