# American Precision Developers (APD Boston) **Trade:** Windows / Siding / Gutters · **Website:** https://apdboston.com/services/window-installation/ · **Languages:** English **Rating: 4.1/5** (medium confidence) — from 10 reviews across 5 sources. 100% of sentiment-scored reviews read net-positive. Last 6 months: 2 reviews, 0 negative. ## The honest read American Precision Developers is a Cambridge, MA general contractor founded in 2021 by Estenio Lima, a master carpenter, and Sara Yoffe, a real estate broker and construction supervisor, and most of its reviews describe the kind of job that takes months, not days: full kitchen, bathroom, and basement renovations, and in a few cases entire multi-floor home rebuilds. Reviewers across Angi and HomeAdvisor from 2022 through this year repeatedly name Sara and a colleague, Stan, for staying hands-on through the whole project — one homeowner describes three separate large jobs with the company over two to three years, spanning a kitchen and living room remodel, a basement refinish, and a primary bedroom and bath. A 2026 review describes gutting and rebuilding an aging bathroom into a safer walk-in shower for an elderly parent, and another 2026 review credits Sara and Stan with designing a galley kitchen around a tricky layout. Landlord clients describe similar results on apartment turnovers and a full multi-unit renovation, saying the process kept moving without them needing to manage it closely. HomeAdvisor's own summary of its five reviews flags two as noting minor scheduling communication issues, though the specific complaints aren't detailed in what's shown. On licensing: the company's Massachusetts home improvement contractor registration and a separate construction supervisor number are both listed as active on BuildZoom, HomeAdvisor, and Angi, though neither has been independently verified against the state registry here — and the two founders' own construction supervisor credentials are self-reported on the company's site, not verified. For a full room renovation or a multi-unit rental turnover, American Precision Developers looks like a solid pick on the strength of repeat, detailed reviews — just confirm current license numbers directly and ask about communication cadence given the couple of scheduling notes on HomeAdvisor. **Strengths:** - Full-scope remodels — kitchen, bath, and basement projects praised start to finish - Repeat clients — one homeowner used them for three separate large projects - Landlord-friendly — apartment turnovers handled with little oversight needed - Hands-on owners — Sara and Stan named directly across multiple reviews **Concerns:** - Scheduling notes — HomeAdvisor flags two reviews citing minor communication issues ## Claims & citations Every claim below is backed by real evidence rows — uncited claims are dropped in code before publication. - The company was founded in 2021 by Estenio Lima, a master carpenter, and Sara Yoffe, a real estate broker and construction supervisor. _(confidence: medium)_ - [Official Website](https://apdboston.com) — “Company history (self-reported): Founded in 2021 by Estenio Lima (licensed construction supervisor & master carpenter) and Sara Yoffe (licen…” - [Official Website](https://apdboston.com) — “Ownership (self-reported): Co-founded and run by Estenio Lima (master carpenter) and Sara Yoffe (construction supervisor & real estate broke…” - A 2026 review describes gutting an aging bathroom and installing a walk-in shower, new vanity, fan, medicine cabinet, and lighting for an elderly parent. _(confidence: high)_ - [Angi](https://www.angi.com/companylist/us/ma/cambridge/american-precision-developers%2C-llc-reviews-11389964.htm) — “5★ I engaged APD to renovate a bathroom in my mom's condo.
