The warranty is the document, not the phrase
“Lifetime warranty” is a sales phrase. A warranty is a document with terms, conditions, exclusions, and a defined transfer process.
The gap between those two things is where most foundation warranty disappointment comes from. This guide covers what to read for, what the common structures are, and what usually voids coverage.
If you are evaluating a house with prior foundation work rather than commissioning your own, our guide on buying a home with previous foundation repairs covers the transaction side.
What is typically covered
Most foundation warranties cover the performance of the supports installed, at the locations covered by the work, within defined tolerances.
In practice that usually means: if a pier installed under the contract settles beyond the stated tolerance, the contractor returns and adjusts it. Some documents include a defined number of readjustments, others are open-ended within the covered scope.
The key phrase is within the covered scope. A warranty on eight piers along the rear elevation covers those eight piers. It does not cover the front of the house, which nobody underpinned.
What is typically not covered
Common exclusions across the industry:
- Cosmetic finishes. Drywall, paint, trim, tile, and masonry respond to humidity and normal building movement independent of the foundation.
- Areas outside the repair scope. Movement in sections not underpinned.
- Plumbing. Under-slab lines are a separate trade and a separate responsibility.
- Acts beyond normal conditions. Flooding, seismic events, and similar.
- Owner-caused conditions. Which brings us to the next section.
None of these exclusions is unreasonable. All of them are worth knowing before you need them.
What voids coverage
Most documents list conditions that void or suspend coverage. Typically:
Unresolved plumbing leaks. A leak saturating soil under the covered area undermines the repair, and most warranties exclude damage arising from one. This is a strong practical argument for hydrostatic testing as part of the project rather than as an optional extra.
Neglected drainage. Water discharging against the foundation for years drives the moisture swings the repair was meant to survive.
Unapproved alterations. Structural changes, additions, or other work affecting the covered area performed without notifying the contractor.
Work by others on the covered area. Another company adjusting the same piers typically ends coverage.
Transferable versus lifetime
These two words get used as though they were the same claim. They are not.
Transferable means a future owner can take over the coverage. This is the one that affects resale value, because a buyer reviewing a home with documented prior foundation work is meaningfully reassured by an active, transferable warranty.
Lifetime is ambiguous unless defined. Lifetime of what: the structure, your ownership, the company? Some documents define it clearly. Some do not, and an undefined term is worth very little.
For transferable coverage, read the mechanism: how long after a sale the new owner has to notify, whether a fee applies, whether an inspection is required, and whether coverage lapses if the process is missed.
Warranty-trust backing
A warranty is only as durable as the entity standing behind it. Some contractors participate in third-party warranty arrangements or trusts intended to provide continuity if the original company ceases trading.
If that backing is offered, it is worth understanding: who administers it, what it covers relative to the contractor’s own terms, and what a claim process looks like. If it is not offered, that is not automatically a problem, but it is worth knowing you are relying on the company itself.
Our position
Our written homeowner warranty is transferable and we provide the actual document before you sign, not a summary paragraph in the proposal. It states what is covered, what is excluded, what voids coverage, and how transfer works.
We do not offer lifetime guarantees we cannot put into readable terms. A warranty you cannot read before signing is not a benefit; it is a phrase.
Questions to ask before you sign
- May I read the warranty document itself, now?
- What exactly is covered, and at which locations?
- What voids coverage?
- Is it transferable, and what does transfer require?
- Is it backed by anything beyond the company?
- What documentation will I receive to support a future claim?
The last one matters more than people expect. A claim years from now rests on the elevation records, installation log, permit sign-off, and warranty document. Keep the package somewhere you will find it.
