Gmp Piping, Inc.

GMP Piping is a Leominster, Massachusetts plumbing company whose one review on file, from 2023, describes a rough copper-piping installation. In that 2023 review, a customer said the work was slow, the job leaked at the end, and the company refused to fix it — the customer brought in New England Orbital to resolve the problems. Its Massachusetts plumber license, 4499-PL-C, is active, and Google shows a 3-star average from 2 ratings. The company's own website describes work on high- and ultra high-purity piping systems built to exact specification, and it is also listed for plumbing on the Procore Construction Network. With only one written account on file, ask directly about the warranty and callback policy on a copper-piping job before hiring.
