About Us

Legacy Plumbing is a commercial plumbing contractor serving the greater St. Louis metro area, handling projects ranging from $25,000 tenant finishes to $3M+ ground-up commercial builds. We're part of Kuesel Holding Company, giving our team the resources of a larger organization while keeping the culture of a hands-on, relationship-driven trade contractor.

The Role

Legacy Plumbing is hiring a Chief Estimator to own our entire estimating function. This is a highly visible, high-ownership role — you'll be the sole person responsible for turning plans into winning, accurate bids across every commercial project we pursue, from small tenant finishes to multi-million-dollar ground-up builds. You'll work directly with ownership and operations leadership, with real influence over how we price, win, and set up jobs for success.

What You'll Do

• Own the estimating process from lead through bid-day submission for all commercial projects, $25,000 to $3,000,000+
• Perform complete quantity takeoffs and build estimates using Trimble AutoBid
• Build, maintain, and continuously refine fixture, pipe, and labor assemblies to reflect real-world material and production costs
• Independently manage the full bid calendar — prioritizing, sequencing, and hitting every deadline with no one else to backstop you
• Solicit, evaluate, and negotiate vendor and supplier quotes
• Review plans and specifications to identify scope gaps, risk, and value-engineering opportunities before they become field problems
• Make the go/no-go and pricing-strategy calls on which jobs to pursue and how aggressively to bid them
• Own the handoff to project management and field leadership after award, ensuring scope and assumptions carry through cleanly to execution
• Track bid-vs-actual performance and use job cost feedback to sharpen future estimates

What You Bring

• 3+ years of commercial plumbing estimating experience
• Trimble AutoBid or STACK experience preferred
• Comfort owning a high-stakes function independently, without a team behind you
• Ability to read and interpret commercial construction plans and specifications
• Strong working knowledge of commercial plumbing systems, fixtures, and materials
• Sharp attention to detail under bid-deadline pressure
• Proficiency with Excel; ability to build and maintain your own estimating tools and structures
