Statement of Work
Ref: 2026-001 • Standard Business Template
Overview
This agreement stipulates that the Installer shall perform the installation of a garbage disposal unit as an independent contractor, not an employee. The Client acknowledges that the Installer is not responsible for the structural integrity of the sink basin or the condition of the dwelling's internal drainage system. Any leaks, clogs, or failures occurring in the piping beyond the immediate disposal connections are considered pre-existing conditions and are outside the scope of this warranty. The Client must ensure the workspace is clear of personal items and hazardous materials prior to the commencement of work.
Limitation of liability is a key component of this contract; the Installer’s total liability for any damages arising from the installation—including water damage or electrical shorts—is strictly limited to the total amount paid for the labor services. The Client agrees to indemnify and hold the Installer harmless against claims resulting from the improper use of the unit, such as the processing of non-food items or exceeding the manufacturer's specified load capacity. All warranties provided are limited to the craftsmanship of the connection points and do not extend to the mechanical components of the unit itself, which are covered solely by the manufacturer’s warranty.
Electrical Code Non-Compliance
Many older homes lack GFCI protection or proper strain relief connectors, which can lead to liability if the new unit draws more amperage than the old circuit can handle.
Dishwasher Knockout Errors
Failing to remove the plastic plug before connecting the dishwasher drain leads to flooding, and a contract must define the testing protocol to prove the system works correctly at handover.
Mounting Flange Seal Failure
Replacing a disposal often reveals thin or corroded sink bottoms that will not hold a seal, making the installer appear responsible for a sink that was already failing.
What is a Garbage Disposal Installer Contract?
A Garbage Disposal Installer Contract template is a formal service agreement that outlines the labor, parts, and safety protocols for installing a kitchen disposal. It protects the contractor by defining the specific plumbing boundaries, addressing electrical requirements, and limiting liability for pre-existing pipe corrosion or sink damage.

This template is based on real-world scenarios across freelance projects where unclear scope, missing payment terms, and revision creep led to lost revenue. It is designed to protect your time, define expectations, and ensure you get paid.
Why Garbage Disposal Installers need a clear contract
Garbage disposal installation is often underestimated as a simple handyman task, but it involves the high-risk intersection of water and electricity. A written contract is vital because it establishes the baseline of the plumbing's condition before you touch a single wrench. It prevents the common situation where a client blames you for a basement leak because you worked on the kitchen sink two floors above. By defining the scope, you protect yourself from performing unpaid work like clearing main line clogs or upgrading faulty electrical circuits. It also ensures you are reimbursed for materials like plumbers putty, tailpiece extensions, or heavy-duty power cords that the client might assume are included in a flat labor rate. Clear terms transform a potentially messy interaction into a professional, high-margin service call.
Real-world scenario
You arrive for what was described as a 45-minute swap of a 1/2 HP Badger unit. Once you get under the sink, you realize the mounting ring is fused to the sink with years of mineral deposits. You spend 30 minutes carefully chiseling it off without scratching the client's expensive copper sink. After the new unit is in, you find the old P-trap is so brittle that it cracks the moment you tighten the slip nut. You now have to drive to the hardware store for a $20 plumbing kit and spend another hour rebuilding the drain line. Because you had no written agreement covering extra labor or material surcharges for unforeseen pipe failure, the client refuses to pay anything beyond the original $125 verbal quote. You effectively worked for $25 an hour after accounting for gas and parts, all while taking on the liability of the new plumbing you installed for free.
🛡️ What this contract covers:
- ✓Removal of existing disposal unit and inspection of sink flange integrity and drainage pipe alignment.
- ✓Installation of the new garbage disposal unit including mounting assembly, drain connections, and dishwasher inlet integration.
- ✓System testing for leaks under maximum water pressure and verification of electrical motor operation and noise levels.
Best practices for Garbage Disposal Installers
Photo Documentation
Take high-resolution photos of the dry cabinet floor and the old unit's connections before starting work to prove existing water damage.
Vibration Testing
Always run the disposal with a sink full of water to check for leaks under the stress of motor vibration and maximum weight.
Material Markups
Clearly state that the quoted price covers labor only, and all required PVC extensions or electrical components will be billed at cost plus a convenience fee.

Frequently Asked Questions
What happens if the existing sink or pipes are too corroded to support a new unit?
The installer will pause work and provide a revised estimate; the client is responsible for the cost of repairing pre-existing plumbing failures triggered by standard installation procedures.
Is electrical rewiring included in this service?
No, this contract covers connection to an existing, functional, and code-compliant power source only; new dedicated circuits or panel upgrades require a licensed electrician.
