Foundation repair warranty: questions to ask before you sign

A long warranty can sound reassuring, but the number of years is only one part of the story. Before signing a foundation repair contract, read what the warranty actually covers, what it excludes, who backs it, how a claim is made and whether the terms change if you sell the home.

Last reviewed: October 1, 2026. Warranty language and contractor requirements vary by company, repair method and state. This guide helps you compare written terms; it is not legal advice.

1. What exactly is covered?

Ask the contractor to identify the covered work in writing. If the project uses piers, anchors, wall reinforcement, drainage or crack repair, the warranty should make clear which installed components or performance promises apply to which part of the project.

2. Is the warranty about workmanship, materials, movement, or all three?

Those are different ideas. A workmanship promise may address how the contractor performed the installation. A manufacturer warranty may apply only to a product or component. A structural or movement-related promise may use its own definitions and limits. Do not assume one warranty covers every issue.

3. How long does each part last?

Ask whether all covered items have the same term. Some contracts use different periods for materials, workmanship, adjustments or other obligations. The written document matters more than a salesperson's summary.

4. Who actually backs the warranty?

Confirm whether the obligation belongs to the local contractor, a parent company, a manufacturer or a third-party warranty provider. Ask what happens if the contractor changes ownership, stops operating or no longer services your area.

5. What conditions can void or limit coverage?

Read exclusions and homeowner obligations carefully. Examples might include drainage conditions, plumbing leaks, landscaping changes, additions, excavation, unusual soil changes or failure to complete recommended maintenance. The exact exclusions should be visible before you sign.

6. Is the warranty transferable to a future owner?

Do not assume transferability. Ask whether a future owner can use the warranty, whether there is a transfer deadline or fee, and what documentation must be supplied. If resale value matters to you, get those terms in writing.

7. What happens if movement continues?

Ask what the contractor is actually required to do if the covered problem returns. Does the warranty provide inspection, adjustment, repair, replacement or another remedy? Does it cover cosmetic restoration, engineering, permits or only the installed system?

8. How do you make a claim?

Get the claim process before the project begins. Ask where to send a request, what evidence is needed, how quickly the company normally responds and whether there are inspection or service fees.

9. Are verbal promises written into the contract?

The FTC advises consumers to make sure promises about work and cost are included in a written home-improvement contract. If a salesperson promises free adjustments, transferable coverage or a specific repair outcome, ask for that promise in the written agreement.

10. Does the warranty match the repair scope?

A warranty cannot fix an unclear diagnosis or vague proposal. Before focusing on the warranty term, confirm the repair method, quantities, locations, engineering, permits, drainage, cleanup and restoration. Use the foundation repair quote checker to organize those details.

Why the written contract matters

The FTC recommends getting multiple written estimates for home-improvement work and carefully reviewing a written contract before work starts. A written estimate should describe the work, materials, completion date and price, and the contract should capture promises made about the project. Requirements vary by state.
