Trusted Plumbing Since 1996 in St. Louis, MO & Surrounding Areas
Legacy Plumbing delivers expert residential and commercial plumbing throughout the St. Louis metro — built on union-trained craftsmanship, reliability, and a deep commitment to doing things right.
A Trusted Name in St. Louis Plumbing
Our founder got his start in 1991, co-founding a plumbing company focused on large custom residential homes. The work demanded precision, problem-solving, and a high standard of finish. Seeing a bigger opportunity in the commercial market, our founder set out independently in 1996 and founded Legacy Plumbing.
Since then, Legacy has grown into a trusted commercial plumbing contractor serving the greater St. Louis region. Our founder brought the same attention to detail from custom-home work into every commercial project, earning a reputation for quality, reliability, and getting the job done right.
That reputation is backed by credentials. Our founder holds master plumbing licenses across St. Charles County, the City of St. Charles, the City of St. Louis, Jefferson County, and numerous municipalities throughout the St. Louis area, along with a master drainlayer and mechanical license in St. Louis County — giving Legacy the licensed reach to serve clients across the metro. Today Legacy Plumbing has master plumbers on staff and is licensed to pull permits throughout the St. Louis area, in every jurisdiction we serve. Legacy Plumbing is a governing member of MCA of Eastern Missouri.
In May 2025, Legacy Plumbing came under new local ownership. Our founder remains actively involved.
