Tommy Plumbing

Tommy Plumbing is a one-man shop in Waltham — Tommy Tam, working out of 13 Montclair Ave, with BBB dating the business to 2008 and counting a single employee. What there is to go on is the permit trail, not customer writing. BuildZoom counts 597 projects on file and 62 permits pulled in the last three years — 12 in 2025, 22 in 2024, 28 in 2023 — spread across Braintree, Brookline, Revere, Randolph, Lowell, Newton, Malden and Boston neighborhoods. Most are plumbing; a handful attach to home additions and sheet-metal work, and the typical permit runs about $4,200. That is the profile of a working residential plumber doing fixture swaps, gas connections and renovation rough-ins, not big-ticket installs. Two things to pin down before calling. BBB has the business listed but issues no rating, saying it lacks enough information to grade it, and the company is not BBB accredited. BuildZoom says a sheet metal licence and three others sit with the Massachusetts board under Tommy M. Tam — that is BuildZoom's reading of the licence records, not a confirmed status, so ask for the plumbing licence number and check it against the Board of State Examiners of Plumbers and Gas Fitters yourself. No customer has written publicly about the work, which means the permit history is the only track record available. For a straightforward plumbing job in the western suburbs, ask for two or three recent references and confirm the licence directly.
