The word “warranty” carries almost no information by itself
Two companies both offer a lifetime warranty. One means a transferable manufacturer warranty on installed pier hardware with a defined service process. The other means an informal promise from a business that may not exist in five years.
The document is what matters, and it comes down to six questions.

The six questions to ask of any warranty
What work is covered? Specifically which installed elements, at which locations. A warranty on piers at the north elevation covers piers at the north elevation. It does not cover the rest of the house, and it does not cover a wall nobody stabilized.
For how long? A defined term in years, or a defined lifetime with a stated meaning.
Who is responsible? The installing company, a manufacturer, or both? Manufacturer warranties on hardware and workmanship warranties from the installer are different instruments with different lifespans and different failure modes.
Can it transfer? And under what conditions — notification periods, transfer fees, inspection requirements. This matters more than most buyers realise, because it affects resale.
What is excluded? The most informative section of any warranty.
What is the service process? How do you make a claim, what response is committed to, and what happens if the parties disagree?
What “lifetime” needs to mean
Ask directly: whose lifetime, and what does it cover?
Common interpretations include the expected service life of the installed product, the period of the original purchaser’s ownership, and the life of the structure. These are materially different, and the difference appears when you sell.
A warranty that is lifetime for the original owner and non-transferable is worth considerably less at resale than one that transfers under stated conditions.
Typical exclusions
Exclusions are not a red flag in themselves; every warranty has them, and honest ones are specific. Common categories include:
- Movement in areas outside the repaired scope.
- New movement from causes the repair did not address.
- Cosmetic finishes — drywall, tile, paint, trim — which typically are not covered even where the structural repair performs.
- Damage from failure to maintain drainage or gutters, particularly where the contractor documented that advice.
- Damage from subsequent alterations, additions, or excavation by others.
- Acts of nature beyond defined parameters.
The exclusion that trips homeowners most often is the drainage one. If a scope advised you to correct downspout discharge and you did not, a claim on subsequent movement may fail on that basis.
Manufacturer versus installer warranties
Pier systems and similar hardware frequently carry a manufacturer warranty covering the product. It survives the installer, which is its main advantage.
Workmanship warranties come from the installing company and cover installation quality. They are only as durable as the company. In an industry with meaningful turnover, that is worth weighing — a twenty-five year workmanship warranty from a three-year-old company is a statement of intent rather than a guarantee.
Ask which you are getting, and whether both apply.
Warranties and resale
Documented, permitted, warrantied repair work is a substantially better position at resale than either undocumented work or an unaddressed problem. A buyer’s inspector will find the evidence of repair either way; what they find alongside it determines how the conversation goes.
Keep the warranty document, the scope, the permit, any engineering report, and photographs together. Our guide on buying or selling after foundation repair covers the transaction side.
Before you sign
Read the exclusions before the coverage summary. Ask for the actual warranty document rather than a description of it. Confirm transfer conditions in writing. Ask what the service process looks like in practice and how quickly the company responds.
Then file it somewhere you will find it in eight years.
