Thomas M. Piersiak & Sons Inc.

Sixty-two years is the number that stands out here. Thomas M. Piersiak & Sons is a Needham Heights plumbing outfit that, by the directory's account, has been working since the early 1960s and takes both residential and commercial jobs. The listed work is plumbing with a bathroom lean — backflow preventer installation, bathtub installation, and bathroom remodeling both full and partial. Beyond that, the public record is empty. There are no customer reviews, no star rating, no licence number published, and no address beyond a PO box. That leaves the tenure as the only real signal, and tenure alone does not tell you how a job goes. If you are considering them for a bathroom or a backflow device in the Needham area, ask for the plumbing licence number and insurance certificate up front, and for two or three recent local references you can actually call.
