Wei Ping Zou

Wei Ping Zou works out of 449 Cambridge St in Lexington, and what exists publicly about him is paperwork rather than customer opinion. BuildZoom counts 24 permitted projects under his name, about nine of them in the past three years, with a typical permit value near $9,000 — the shape of a working plumber taking steady small-to-mid jobs rather than a renovation outfit. No homeowner has written about him on BuildZoom, so there is nothing here about how he schedules, communicates, or prices a job. Two things are worth raising on the first call. BuildZoom lists a Massachusetts plumber registration, #13538, and a sheet metal registration, #13571, for him, plus a journeyman and master plumber entry it last checked back in 2016 — those are the directory's own claims rather than confirmations from the state board, so ask him for the current numbers and check them yourself. It also shows a Massachusetts home improvement contractor registration, #121099, as inactive, noting the status was at one point cancelled; that matters if your project is a renovation rather than straight plumbing. For a defined plumbing job around Lexington, the permit trail at least shows continuing, recent activity. For anything larger, verify the licences with the Commonwealth and ask him for references, because nobody has left a written account of hiring him.
