# American Precision Developers, LLC (Cambridge, MA) **Trade:** Carpentry · **Website:** https://apdboston.com/ · **Languages:** English **Rating: 3.0/5** (low confidence) — from 7 reviews across 5 sources. 100% of sentiment-scored reviews read net-positive. Last 6 months: 0 reviews, 0 negative. ## The honest read American Precision Developers says it was founded in 2021 by Estenio Lima and Sara Yoffe and is based in Cambridge, serving nearby Massachusetts communities. The company describes work in bathroom and kitchen remodeling, basements, additions, siding, decks, flooring, windows, painting, ADUs and masonry; its founders say they lead the team, and the website describes them as a construction supervisor and master carpenter and a construction supervisor, respectively. The seven written reviews span 2022–2023. In a September 2023 review, a homeowner said a bathroom remodel was completed on time and as planned while the family was away, and praised clear communication. In April 2022, a customer described apartment kitchen and bathroom renovations as stress-free and said the team kept the work moving. A November 2022 homeowner cited siding, an outdoor storage space and smaller repairs, saying the crew handled some extra work without added cost and later quoted additional jobs below prior quotes. Scheduling is the clearest point to discuss before signing. A May 2023 reviewer said a renovation involving laundry installation and a permit took patience during the holiday season and warned that work could not be moved ahead of schedule; the November 2022 customer also wanted more advance notice about which days the team would be on site. Both reviewers still spoke positively about the finished work, but their comments make timing and daily updates useful items to settle early. The company may fit homeowners planning a multi-room renovation, addition or restoration who want one general contractor coordinating the work. Ask for a written schedule, how changes affect the timeline, and who will provide updates. Its website says it is licensed and insured in Massachusetts, while directory profiles list license numbers; confirm the applicable credentials with the state before relying on those claims. **Strengths:** - Bathroom renovations — a 2023 customer praised timely completion and clear communication - Scope flexibility — a 2022 homeowner said extra work came without added cost - Kitchen and bath work — apartment customers praised smooth renovations **Concerns:** - Schedule coordination — 2022 and 2023 reviewers wanted clearer timing and advance notice ## Claims & citations Every claim below is backed by real evidence rows — uncited claims are dropped in code before publication. - American Precision Developers says it was founded in 2021 by Estenio Lima and Sara Yoffe and serves Cambridge and nearby Massachusetts communities. _(confidence: high)_ - [Official Website](https://apdboston.com) — “Company history (self-reported): Founded in 2021 by Estenio Lima and Sara Yoffe, who say they built the company around quality, transparency…” - [Official Website](https://apdboston.com) — “Stated service area (self-reported): Boston, Cambridge, Somerville, Brookline, Newton, Arlington, Watertown” - The company lists bathroom, kitchen, basement, addition, siding, deck, flooring, window, painting, ADU and masonry work. _(confidence: high)_ - [Official Website](https://apdboston.com) — “American Precision Developers is a Cambridge-based Massachusetts general contractor specializing in residential renovations, remodeling and …” - [Houzz](https://www.houzz.com/professionals/general-contractors/american-precision-developers-llc-pfvwus-pf~1833325005) — “Services offered (Houzz): Home remodeling, Bathroom remodeling, Kitchen remodeling, General contracting, Home additions, Custom homes, New h…” - In September 2023, a bathroom-remodel customer said the work finished on time and praised clear communication. _(confidence: high)_ - [HomeAdvisor](https://www.homeadvisor.com/rated.AmericanPrecision.125108654.html) — “5★ We just had our bathroom remodel done by American Precision Developers and they did an amazing job from start to finish.
