A plumbing contract is a written agreement between a plumber and a customer that sets out the plumbing work to be done, who supplies the fixtures and materials, permits and inspections, how hidden problems behind walls are handled, the price and payment terms, the schedule and the warranty on parts and labor. It protects both sides when a job uncovers more than expected.

Plumbing Contract: common questions
What should a plumbing contract include?
The scope of work, who supplies fixtures and materials, permits and inspections, how hidden conditions are handled, the price and payment schedule, the timeline, the labor warranty and manufacturer warranties, and signatures.
Who pays for wall repairs after plumbing work?
Unless the contract says otherwise, plumbers usually leave access openings clean but unfinished, and drywall or tile repairs are a separate cost. Spell this out in the 'excluded work' section to avoid arguments.
Does a plumber need a permit?
Many jobs do — water heater replacements, repipes, new fixtures and gas work commonly need a permit and inspection. Requirements are set locally, so the contract makes it clear who pulls the permit and that the cost is included.
How long should a plumbing warranty be?
One year on labor is common for installation work; fixtures and water heaters carry their own manufacturer warranties, often longer. The template lets you set the labor warranty.
Is this contract legally binding?
A signed contract with an agreed scope and price is generally binding, but home-improvement contract rules vary by state. This is a template, not legal advice.
