Plumbing Service Agreements
If you are hiring a plumbing contractor or offering services as one, plumbing contracts are vital to the project’s outcome in several ways. Having a sound contract in place before work begins is critical, whether the project is small or large. Before drafting your document, hire a lawyer to write it or help you learn more about how to negotiate a contract.
What Are Plumbing Contracts?
Plumbing contracts, also known as plumbing service contracts, are legally binding service contracts that specify the type of work that a plumber should perform. These agreements protect both the property owner and the service provider. A plumbing contract details the project’s scope and depth, including price and a Statement of Work, or as part of a larger construction contract.
Benefits of Plumbing Contracts
Regardless of whether you are a property owner or plumbing contractor, there are several benefits associated with plumbing contracts. The most significant advantage of plumbing contracts is that they require both parties to reach an agreement before work evens begin and protects them if a dispute arises. While verbal contracts may be tempting, ensure that you get your project in writing beforehand.
Benefits of plumbing contracts include:
- Saving both parties time and money
- A guarantee of work performed
- Reassurance when offering ongoing maintenance
- A legal record of the relationship and purpose
- An agreement of how disputes will be handled
- Understanding of how much the project will cost
- A description of guarantees and warranties
There are several types of plumbing contracts, including ongoing services and one-time projects. No matter what kind of agreement you need in place depends upon the job and plumber you are hiring. Speak with a contract lawyer to help you draft and execute an enforceable agreement that protects both parties and meets specific legal rules and regulations.
What Should Be in a Plumbing Contract?
The plumbing contractor is the one who generally presents a plumbing contract. As such, it is vital to understand that there are specific elements to include for enforceability and other legal reasons.
Here is what should be in a plumbing contract at a bare minimum:
- Both parties’ names and contact information
- Detailed outline of the project scope and depth
- Detailed itemization of materials used
- Written description of the service payment schedule
- Types of permits required by law and local ordinances
- Proof of professional licensure, bond, and insurance
- Construction cleanup and post-work responsibilities clause
- How non-payments are handled, including service termination and liens
- Warranties and guarantees to the customer
- Completed copy of your invoice template to present upon signing
You should have a plumbing contract that is very specific and customized to the job at hand. If you have any questions about your agreement or how you can improve it, seek legal advice from an attorney in your state for help.
How Do I Write a Plumbing Contract?
It is challenging to write a plumbing contract without possessing a solid command of contract law. While it may seem costly or difficult to hire a contract lawyer, there are a few ways that you can still keep your legal costs in check while protecting your rights as a plumbing contract or consumer.

Plumbing Contract

Can a plumbing contractor change the terms of a signed contract without my consent?
I recently hired a plumbing contractor to repair some leaks in my home, and we signed a contract that clearly outlined the scope of work, timeline, and cost. However, after a few days, the contractor informed me that they would need to change some of the terms, including an increase in the cost and an extension of the timeline, without providing any valid reasons or seeking my consent. I'm concerned about my rights as a consumer and whether the contractor can unilaterally modify the contract in this manner.
Merry K.
Speaking very generally, the answer will depend on the wording of the contract itself, and just what you agreed to. However, it's common for this type of contract to include provisions for a work change order. Look to see if your contract includes a reference to something like a "change order" - this is usually how the reference to the formal document used to modify the original contract is call - typically for: Additional work, Changes in scope or materials, Adjustments to cost or timeline. It must be agreed to and signed by both parties (typically the contractor and homeowner or project owner) before the change is performed, unless the contract provides otherwise. The key is whether or not your contract provides otherwise. Sometimes contracts allow for extra time/materials that a contractor may find once walls are opened and whether hidden defects and problems can be seen. Your plumber should explain to you the reasons for the extra charges. I hope that's been helpful. Don't forget you can find a residential contruction contract attorney through ContractsCounsel.com to review the contract and negotiate with the plumber on your behalf. (I do not do this kind of work myself right now).
Quick, user friendly and one of the better ways I've come across to get ahold of lawyers willing to take new clients.
