# Foundation Repair Warranties: What They Cover > A numbers-first guide to foundation repair warranties, coverage limits, transfer fees, and what voids protection. Canonical: https://foundationrepairlab.com/foundation-warranty/ Last updated: 2026-11-09 ## What a Foundation Repair Warranty Covers A foundation repair warranty covers the specific repair method performed, not the entire foundation or future soil movement. If a contractor installs push piers to stabilize a settling slab, the warranty typically guarantees that those piers will hold the structure at the repaired elevation. It does not cover new cracks in unrelated areas, cosmetic drywall repairs, or damage caused by changes you make to drainage or landscaping after the work is complete. Warranty terms vary by repair method and contractor. Push piers and helical piers are commonly backed by lifetime, transferable warranties. Slab lifting methods such as mudjacking or polyurethane foam injection usually carry shorter terms, often aligned with the expected life of the material rather than the structure itself. ## Types of Warranties and Typical Terms Most foundation repair warranties fall into one of three categories: 1. **Manufacturer’s material warranty** – Covers defects in the pier, bracket, or foam product itself. These terms are set by the product maker and may run for decades or lifetime. 2. **Contractor workmanship warranty** – Covers installation errors, such as a pier not reaching bearing depth or a slab not returning to the specified elevation. Terms typically range from one year to lifetime. 3. **Combined system warranty** – Covers both materials and installation under a single document. This is the most common format for residential pier jobs. Pier warranties are often advertised as lifetime and transferable. That means the original homeowner and subsequent buyers can make a claim if the warranted piers fail. Transfer usually requires notice within a set window after the sale and payment of a transfer fee. ## What Voids a Warranty Warranties contain exclusions, and understanding them matters more than the length of the term. Common voids include: - Making structural changes without notifying the warranty holder, such as adding a second story or a heavy masonry feature. - Altering drainage around the foundation, including new downspout placement, irrigation changes, or regrading that directs water toward the slab. - Hiring another contractor to perform foundation work or cosmetic crack repairs on the same walls. - Failing to maintain gutters, downspouts, or surface drainage in a way that contributes to soil saturation or erosion. - Ignoring recommended maintenance, such as monitoring crack width after repair. If a claim is denied, the contractor or warranty administrator should cite the specific clause. Request the denial in writing and compare it to the signed contract before accepting the outcome. ## Transferability and Fees A transferable warranty can add value when selling a home, but it is not automatic. Most contracts require the new owner to request transfer within a defined period, often 30 to 90 days after closing. The transfer fee typically ranges from $100 to $500. For context, a typical pier job costs $6,000 to $30,000. Push piers run roughly $1,000 to $3,000 each, while helical piers run about $700 to $2,500 each. If a job requires eight piers at $2,000 each, the material and installation subtotal is $16,000. A lifetime transferable warranty on that work protects a significant portion of the investment for the next owner, provided the transfer paperwork is completed on time. ## Warranty vs. Insurance vs. Engineer Inspection Homeowners sometimes confuse a repair warranty with homeowners insurance. They are not the same. A warranty is a contract between you and the repair contractor or warranty administrator. Insurance is a policy between you and an insurer, and it generally covers sudden, accidental events rather than gradual soil movement or settling. An engineer inspection is a separate step that should happen before repair work begins. A structural engineer measures crack width, displacement, and depth to bearing, then recommends a method. Inspections typically cost $400 to $1,500 and take one to two weeks to schedule. The resulting report becomes a reference point if you ever need to file a warranty claim, because it establishes the baseline condition of the foundation. Permits also vary by city and county and typically take one to three weeks to obtain. A warranty does not replace permit requirements, and unpermitted work can complicate both resale and future claims. ## Cost Context and Repair Methods Warranty value should be weighed against the repair method and cost. Average foundation repairs range from $4,000 to $15,000, while major structural work can reach $20,000 to $40,000. Full foundation replacement runs $40,000 to $150,000. Restoration typically costs 10 to 25 percent of structural replacement value. Common repair methods and their typical cost ranges include: - Push piers: $1,000 to $3,000 each - Helical piers: $700 to $2,500 each - Mudjacking: $3 to $8 per square foot - Polyurethane foam lifting: $5 to $15 per square foot - Slab lifting: $3 to $12 per square foot - Carbon fiber straps: $400 to $1,200 per strap - Wall anchors: $500 to $1,500 each - Crawl space encapsulation: $3 to $8 per square foot, or $4,000 to $15,000 per job For example, if a 400-square-foot garage slab is lifted with polyurethane foam at $10 per square foot, the job costs about $4,000. A warranty on that work should specify whether it covers settlement recurrence, foam degradation, or both, and for how many years. Crack width also informs whether a warranty claim is justified. Cracks under 1/16 inch are generally cosmetic. Cracks at or above 1/8 inch warrant monitoring. Wall movement beyond 2 inches may indicate that repair, rather than continued warranty coverage, is the appropriate path. If a foundation has failed beyond roughly one-third of its structural capacity, replacement is usually considered instead of further repair. ## Choosing a Contractor With a Clear Warranty Before signing a contract, request the warranty document in writing and confirm the following: - Who administers the warranty: the contractor, a third-party administrator, or the manufacturer. - The exact term for materials and for workmanship. - Whether the warranty is transferable and the fee for transfer. - The claims process, including inspection timelines and who pays for a diagnostic visit. - Exclusions related to drainage, landscaping, and future loads. Compare warranty terms across at least two contractors. A longer term is not automatically better if the exclusions are broad or the administrator is difficult to reach. Pair the warranty with an independent engineer inspection so you have a measured baseline before any piers are installed or slabs are lifted.
