Free Commercial Plumbing Subcontractor
Service Agreement
One pinhole leak or a handshake deal on a high-rise will bleed your bank account dry before the drywall is even up. Without a rock-solid contract, you’re just one 'misunderstanding' away from losing your gear, your truck, and your reputation to a predatory General Contractor.
Pro Contractor Tip
Include a 'Pay-When-Paid' protection clause to ensure your check isn't held hostage by the owner's beef with the GC.
Why use a written agreement?
Handshake deals are risky. As a Commercial Plumbing Subcontractor, "scope creep" is your biggest enemy. A clear agreement ensures everyone agrees on the deliverables before money changes hands.

Frequently Asked Questions
What do I do when the GC asks for a 'quick' change that isn't in the prints?
Stop the tools and get a signed Change Order immediately. Your contract defines the scope, and anything outside that is a new billable event that protects your overhead.
How do I handle it when the site isn't ready for me to start plumbing?
Enforce a 'Site Readiness' clause in your agreement that triggers a daily standby rate. If you're burning daylight because they haven't cleared the slab, they need to pay for your lost time.
The GC is holding my final 10% retention for months; how do I get it?
Your contract should define 'Substantial Completion' based on your final inspection, not the entire building's move-in date. This forces the payout once your specific pipes are signed off by the city.
