Clear written protection
What this guarantee is designed to do
A craftsmanship guarantee addresses the installation work performed by the contractor. It is separate from manufacturer product warranties, which may cover materials under their own terms.
Keep your proposal, final invoice, product information and warranty documents together. If a workmanship concern appears, documentation helps the team understand the original scope and evaluate the concern efficiently.
Questions to review before work begins
- What work is included in the written scope?
- Which craftsmanship guarantee applies to this project?
- What product or manufacturer warranties apply?
- How are requested changes or concealed conditions documented?
- What records should the homeowner keep after completion?
