Statement of Work
Ref: 2026-001 • Standard Business Template
Overview
This Agreement governs the professional installation of radiant floor heating systems, ensuring that all work is performed according to manufacturer specifications and local building codes. The Client acknowledges that the Installer is responsible solely for the heating components and their immediate functionality; the Client must ensure the structural integrity of the subfloor and provide a clean, level surface prior to the commencement of work. Failure to provide adequate insulation below the system may result in diminished thermal performance, for which the Installer shall not be held liable.
Upon completion of the heating element installation, the Installer will perform a documented pressure or continuity test to verify system integrity before the final floor covering is applied. The Installer’s liability is strictly limited to the heating system itself and explicitly excludes the cost of removing, repairing, or replacing any finished flooring materials (such as tile, stone, or wood) should a system failure occur after the floor has been sealed by a third party. All electrical or plumbing connections to the main house supply must be performed by licensed professionals as required by local law.
Subfloor Preparation Failures
If the slab or wooden subfloor is not perfectly flat or clean, the heating mats or tubing may fail or cause the finished flooring to crack over time.
Post-Installation Damage
Carpenters or flooring installers often accidentally drive fasteners through heating loops after you have completed your rough-in and left the site.
BTU Output Misunderstandings
Clients may change window specifications or insulation levels after your heat loss calculation is done, leading to a system that cannot keep the room warm.
What is a Radiant Floor Heating Installer Contract?
A Radiant Floor Heating Installer Contract template is a specialized agreement that defines the design, installation, and testing protocols for hydronic or electric floor heating. It protects installers by setting clear expectations for subfloor conditions, pressure testing verification, and liability for damage caused by other contractors after the heating elements are installed.
Built from real freelance projects
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 Radiant Floor Heating Installers need a clear contract
Radiant floor heating is a high stakes trade because your work is permanently buried under concrete or expensive hardwood. If the system fails or performs poorly due to bad insulation or a change in floor thickness, the cost of remediation is astronomical. A written contract protects you by defining the thermal output limits and the exact site conditions required for a successful install. It prevents the homeowner from blaming you when their choice of thick rugs prevents the heat from reaching the room. It also establishes clear boundaries regarding who is responsible for the electrical supply and the structural integrity of the subfloor. Without these specifics, you are essentially providing an open ended warranty for every other trade on the job site.
Real-world scenario
You finish a high end electric floor heating install in a master bathroom and verify the continuity with a loudmouth sensor. The project seems perfect. Two days later, the tile contractor arrives and uses a sharp metal trowel to spread thin-set. They nick the heating wire in three places but cover it up to stay on schedule. When you return to install the thermostat, the system shows an open circuit and will not heat. Because you did not have a signed contract stating that the system was tested and accepted in working order by the general contractor before the tile was laid, the homeowner demands you pay for the removal of the new marble floor. You spend three days using a fault locator and chipping up tiles at your own expense. You lose your profit on the job and another 2,000 dollars in replacement materials because your liability boundaries were not in writing.
🛡️ What this contract covers:
- ✓Phase 1: Subfloor preparation assessment and installation of thermal insulation or vapor barriers.
- ✓Phase 2: Layout and secure mounting of hydronic tubing or electric heating elements according to thermal design specifications.
- ✓Phase 3: Integration with manifold or thermostat controls followed by final system pressure testing and certification.
Best practices for Radiant Floor Heating Installers
Photo Documentation
Take high resolution photos of every loop and sensor location next to a tape measure before the system is covered.
Electrical Requirements
State explicitly that the client must provide a dedicated circuit at the thermostat location to prevent system overloads.
Material Exclusions
Clearly list that you are not responsible for the cost of self-leveling compound if the subfloor is more than a quarter inch out of level.

Frequently Asked Questions
Is the installation of the final floor covering included in this contract?
No, this agreement covers the radiant heating system only; the client must hire a separate contractor for tile, hardwood, or laminate installation.
What happens if a leak or break occurs during the finish flooring installation?
The installer provides a successful pressure test prior to floor covering; damage caused by third-party flooring contractors is the responsibility of the client.
