# Home Warranties and Foundations: What Is Covered > Standard home warranties rarely cover foundation repair. Learn what structural warranties, builder warranties, and insurance actually pay for. Canonical: https://foundationrepairlab.com/home-warranty-foundation/ Last updated: 2026-11-09 Most standard home warranties do not cover foundations. If you are looking at a home warranty contract, foundations and other structural systems are typically listed as exclusions. Coverage for foundation problems usually comes from a builder’s structural warranty, a separate structural policy, or it does not exist at all. Home warranties and foundations operate under different rules. A home warranty is a service contract that repairs or replaces home systems and appliances, such as HVAC, plumbing, and electrical. Foundations are structural, not mechanical, so they fall outside most standard plans. Before assuming a repair is covered, measure the problem first: crack width, displacement, and movement determine whether the issue is cosmetic, structural, or an emergency. ## What Standard Home Warranties Cover Standard home warranties generally cover items with moving parts or serviceable components. Foundations are static structural elements, so they are commonly excluded. Even when a warranty mentions “structural,” the language often limits coverage to specific components or excludes soil-related movement, settling, and expansion. Read the contract exclusions carefully. Common exclusions include: - Pre-existing conditions - Soil movement, settling, or expansion - Poor construction or improper site preparation - Cracks below a specified width, often 1/8 inch or less - Damage caused by flood, earthquake, or tree roots If your contract does not explicitly list foundation repair as a covered item, assume it is not covered. ## Builder Warranties and Structural Coverage New construction often includes a builder’s warranty. Structural coverage for load-bearing elements, including the foundation, commonly runs for 10 years. This is different from a home warranty you buy for an existing home. Builder warranties may transfer to subsequent owners, sometimes for a transfer fee of $100–$500. To make a claim, you usually need documentation showing the defect appeared during the coverage period and resulted from builder workmanship or materials, not normal settling. An engineer inspection, which costs $400–$1,500, is often required to establish cause. ## Homeowners Insurance vs. Home Warranties Homeowners insurance and home warranties are not interchangeable. Insurance covers sudden, accidental damage from a covered peril, such as a vehicle crashing into the foundation or a burst pipe causing collapse under specific conditions. It generally does not cover settling, soil movement, or wear and tear. Flood and earthquake damage are usually excluded from standard homeowners policies and require separate coverage. If you live in an area with expansive soil or seismic risk, review your policy declarations page for exclusions and consider endorsements where available. ## When Foundation Repairs Become Necessary Not every crack requires repair, and not every repair is covered. Use crack width as a first filter: - Hairline cracks up to 1/16 inch are typically cosmetic. - Cracks at or above 1/8 inch warrant monitoring and possible professional evaluation. - Wall movement approaching 2 inches may indicate serious structural distress. If repair is needed, costs vary by method. Common foundation repair estimates include: - Push piers: $1,000–$3,000 each - Helical piers: $700–$2,500 each - Full pier job: $6,000–$30,000 - Mudjacking: $3–$8 per square foot - Polyurethane foam lifting: $5–$15 per square foot - Slab lifting: $3–$12 per square foot - Carbon fiber straps: $400–$1,200 per strap - Wall anchors: $500–$1,500 each - Crawl space encapsulation: $3–$8 per square foot, or $4,000–$15,000 per job Average total foundation repair falls in the range of $4,000–$15,000. Major structural work can reach $20,000–$40,000. Full foundation replacement may cost $40,000–$150,000. These are estimates; actual price depends on soil conditions, access, pier count, depth to bearing, and local labor rates. For example, if a contractor recommends eight push piers at $2,000 each, the pier cost alone is $16,000. Adding mobilization, permits, and engineering could push the job toward the upper end of the $6,000–$30,000 range. If the same house used helical piers at $1,500 each, the material and installation cost would be $12,000 before additional job costs. ## What to Do Before Filing a Claim Measure first, then contact your provider. Take dated photos of cracks, note widths with a crack gauge, and record any sticking doors or uneven floors. If you have a builder warranty or structural endorsement, locate the original contract and confirm the coverage term and transfer status. An engineer inspection costs $400–$1,500 and typically takes 1–2 weeks to schedule. The inspection report identifies the cause of movement and whether it falls under a covered peril or warranty provision. Without this documentation, most insurers and warranty administrators will deny or delay a claim. Permit requirements vary by city and county and typically take 1–3 weeks to approve. Factor this into your timeline if structural repair is approved. ## Repair Methods and Warranty Terms If you pay out of pocket, ask about warranty terms for the repair itself. Pier systems are often warranted for life and may be transferable, which can support resale value. Mudjacking and polyurethane foam lifting are generally not lifetime solutions; mudjacking, for example, may last 5–15 years depending on soil and drainage conditions. Carbon fiber straps and wall anchors address bowing or cracked foundation walls. These are targeted repairs, not whole-foundation solutions, and their warranties vary by manufacturer and installer. Get warranty terms in writing before signing a contract. ## Bottom Line Most home warranties exclude foundations. Structural protection usually comes from a builder’s warranty on new construction, a separate structural policy, or homeowners insurance for sudden covered losses. For existing homes, assume foundation repair is an out-of-pocket expense unless your contract explicitly says otherwise. Start with an engineer inspection to document the problem, then check your warranty and insurance documents for exclusions before expecting coverage.
