How to Use This Template
- 1
Fill in both parties completely: your company name, license number, insurance info, and the client’s full legal name and property address. Incomplete party identification is the most common reason plumbing contracts fail to hold up in disputes.
- 2
Write the scope of work in specific, measurable terms. Instead of "replumb the bathroom," write "Remove existing galvanized supply lines and replace with 3/4-inch PEX to all bathroom fixtures including sink, toilet, and shower valve." Specificity prevents scope creep.
- 3
Include a clear change order procedure: any work beyond the original scope requires a written change order signed by both parties before work begins. This single clause prevents more contractor-client disputes than any other provision.
- 4
Add your state’s required contract language. Many states require specific disclosures for home improvement contracts (right to cancel, license number display, lien waivers). Check your state licensing board’s requirements.
Frequently Asked Questions
Do I need a contract for every plumbing job?
Yes. Even small jobs should have a written agreement. For jobs under \$500, a simplified one-page contract is fine. For anything larger, use a full contract. Written agreements protect both you and the client and are required by law in many states for home improvement work.
What should a plumbing contract include?
At minimum: both parties’ names, the property address, a detailed scope of work, total price, payment schedule, start and completion dates, warranty terms, and signatures. For jobs over \$1,000, also include change order procedures, insurance requirements, and dispute resolution.
Is this contract template legally binding?
This template provides a professional starting point. However, contract requirements vary by state. We recommend having a licensed attorney in your state review and customize the template for your business. This template does not constitute legal advice.
How do I handle change orders in my plumbing contract?
Include a clause requiring written change orders for any work outside the original scope. The change order should describe the additional work, the cost impact, timeline impact, and require both signatures. Never start extra work without a signed change order.
