JZ4S contractor LLC

JZ4S Construction LLC is a Chelsea remodeling outfit that shows up for the kind of call a burst pipe triggers — drywall torn open, paint peeling, a hallway that needs putting back together. The company says it's been running for eight years and works across dozens of Greater Boston towns, from Cambridge and Brookline to Lynn and Malden. The handful of reviews on file lean the same direction: fast, communicative, and clean. A homeowner who hired them through Houzz in early 2026, after a pipe broke in a hallway, said the repaired drywall and paint "looks better than ever," with Jessica, Jose and Luis named as friendly and in regular contact throughout. A separate Google reviewer in 2025 called the crew prompt and said they left repaired areas cleaner than they found them. Google shows a 5★ average from 7 ratings and Houzz a 5.0★ from 2, with two Houzz project badges. One thing worth asking about before booking: an older 2017 review sitting on this same Houzz profile is actually attributed to a different company, JB Painting and Construction Corp, not JZ4S — it's unclear whether that's an earlier name for the same team or an unrelated listing carried over. Worth confirming exactly who you'd be working with. Beyond repair work, the company's own site lists kitchen and bath remodels, additions, flooring, and fencing, though the reviews on file describe drywall and paint repair rather than full room remodels — solid evidence for a repair or painting job, less for gauging a ground-up kitchen renovation.
