American Precision Developers

American Precision Developers works out of Cambridge, and the project that keeps recurring in its reviews is the same one: turning an old tub into a walk-in shower for someone who needs it. The company says it was started in 2021 by Estenio Lima, a master carpenter and licensed construction supervisor, and Sara Yoffe, a lawyer and real estate broker who also holds a construction supervisor license, and that it covers Cambridge, Boston, Somerville, Brookline, and Newton. The last several months of reviews read like a run of the same job done well: a shower/tub combo from the 1980s gutted and rebuilt into a walk-in with a new vanity and lighting for a customer's mother, a Cambridge master bathroom redone from scratch, and an older homeowner's bathroom converted for easier access with daily check-ins while the crew worked. On the kitchen side, a June 2026 review singles out a full galley-kitchen remodel, and another describes a bathroom fix where the crew added custom cabinetry to solve a storage problem while keeping costs down. Reviewers describe working directly with Sara and a colleague named Stan on site, not a rotating cast of subcontractors. Across 32 reviews on Google and Angi going back to 2024, the rating has stayed at 5 stars the whole time, and none of the last six months' worth turned negative. Worth knowing before you call: several of the Google and Angi reviews are worded almost identically, which means some of that 32-review total is the same customers posting twice rather than 32 separate households — the underlying praise is real, but the count overstates how many distinct people it represents. On the paperwork side, its Massachusetts home improvement contractor license (#203659) is active and doesn't expire until December 2027. This reads like a good fit for a Cambridge-area bathroom or kitchen remodel, particularly one centered on accessibility — grab bars, walk-in showers, aging-in-place layouts — given how often that specific job shows up in its recent history. Before booking, it's worth asking who's actually on site day to day beyond Sara and Stan, since a small, founder-run shop's own calendar is usually the real constraint on scheduling.
