- A plumbing service agreement states the tasks the plumber will perform
- These documents protect clients and plumbers alike
If you’ve been asked to sign a plumbing service agreement or are a plumber and need to know whether to write one, having a clear idea of what these documents cover makes a difference.
What Is a Plumbing Service Agreement?
A plumbing service agreement is a contract between a plumber and a client. There are two main types of these documents, including a one-time job agreement and a maintenance plan.
What This Contract Covers
This type of contract will cover what the client can expect regarding routine maintenance, priority repairs and safety inspections. They will typically not include the cost of major repairs or the replacement of heaters or pipes.
Types of Maintenance Plans
Clients can choose a basic care plan, which includes a yearly system check. The plumber will check for leaks, flush the water heater and test water pressure. A client with this plan will generally be first in line if they have an emergency.
There are home protection plans, too. These provide perks that the basic plan may not offer. For one thing, clients can get discounts on plumbing repairs. The plumber may even waive or reduce the standard trip fee.
Clients may also have access to premium maintenance plans. These include free or highly affordable drain cleaning services. Clients will be guaranteed to get fast emergency help.
Key Terms to Include
Anyone who drafts service agreements must include clear terms regarding the scope of the work. List the tasks and materials that will be needed. The pricing and payment expectations have to be clear, too. If there are services that are excluded, they need to be listed.
The plumbing service agreement should include the plumber’s credentials. In almost every state in the country, a plumber will need to have a license.
In Texas, for example, plumbers can obtain an apprentice, tradesman-plumber limited, journeyman or master plumber license to work in the industry. Master plumber licenses are required for those who start their own business.
In Ohio, however, individual journeyman plumbers don’t need a license in the majority of cities. A license will be needed if the plumber chooses to work as a commercial plumbing contractor.
How to Write One
To write a plumbing service agreement, include all of your contact information. Add the start date and the expected end date of the project.
Describe the work you will perform and list what will not be included. You should also clearly list what everything will cost, along with the payment terms. If you offer warranties, state this. Both parties should sign the agreement.
Benefits for Both Sides
An agreement protects both parties. It ensures the plumber gets paid for their work and is not sued for not performing certain tasks. Clients have protection if the plumber doesn’t fulfill their part of the deal.
Deciding if It's Worth It
Writing a plumbing service agreement can be vital when it comes to large projects, but it may not be so essential for smaller ones. Consider the risk in each case before deciding whether you need one.

Frequently Asked Questions
Everything you need to know about our plumbing service agreement template
A plumbing service agreement is a legally binding contract between a plumber and a client that defines the scope of plumbing work, service type, emergency rates, parts and labor warranties, fixture specifications, permit responsibilities, and payment terms. It protects both parties and ensures clear expectations for the plumbing service.
The agreement itself does not require a license, but nearly all states require plumbing licenses for professional plumbing work. Operating without a valid license can void the agreement, result in fines, and create liability issues. Always verify your state's licensing requirements and include your license number in the agreement.
Document your rate structure clearly: standard hourly rate, after-hours rate (evenings), weekend rate, and holiday rate. A common structure is 1.5x for evenings and weekends, 2x for holidays. Include a minimum service charge for emergency calls. Having these rates in a signed agreement prevents disputes about billing after an emergency.
Offer separate warranties: 1-2 years on workmanship (labor) covering installation defects, leaks from joints you made, and connection failures. Parts carry the manufacturer's warranty (typically 1 year to lifetime depending on the product). Exclude damage from misuse, freezing, pre-existing conditions, and client modifications.
Permits are typically required for: new plumbing lines, water heater installations, sewer line work, gas line modifications, adding new fixtures, and major remodeling. Minor repairs like replacing a faucet or unclogging a drain usually do not require permits. Requirements vary by jurisdiction — always check local building codes.
