Commercial Plumbing Subcontractor for St. Louis GCs — Send Us Your Bid
For GCs, estimators and developers: plan & spec, design-build and design-assist plumbing with self-performed underground, union UA Local 562 crews, and written bids within one business day.
How do I send Legacy Plumbing plans or an ITB?
Send your plans, specs or invitation to bid through our contact and bid form, or call 636-978-0120. We return written bids within one business day.
What delivery methods do you work under?
We bid plan-and-spec work from your engineer's drawings and self-perform the install, and we partner on design-build and design-assist preconstruction with early budgets, value engineering and BIM coordination.
Do you self-perform underground and site utilities?
Yes. We self-perform underground plumbing and site utilities — sanitary, storm and water services — with our own excavation crews.
Can I get civil site work and plumbing from one company?
Legacy Plumbing is part of the Kuesel family of companies. Our sister company Kuesel Excavating Co. handles excavation, site utilities and grading, so GCs can get civil and plumbing scopes from one family of companies.
Are your crews union?
Yes. Legacy Plumbing is a UA Local 562 signatory commercial plumbing contractor serving St. Louis since 1996.
What types of projects have you built?
Our projects include cold storage, schools, industrial buildings, dental and medical offices, a car wash, multi-family rough-in and ground-up site utilities across the St. Louis area.
What area do you cover?
We work across the St. Louis metro and a 2-hour radius from our shop at 811 N Main St, O'Fallon, MO.
