Note: This guide explains common policy language in general terms. It is not legal or insurance advice. Your own policy, endorsements and state law decide what is covered; ask your agent or insurer.
The short answer
Most homeowners policies do not pay to repair a foundation that has settled, cracked or moved because of the soil. Two standard exclusions do most of the work: one for settling, shrinking, bulging or expansion of foundations, walls and floors, and one for earth movement. Courts in many states have upheld these exclusions, including in cases where a plumbing leak washed out soil under a slab. Some states and some policy forms treat certain situations differently, so the details matter.
What is usually excluded
- Settling, shrinking, bulging or expansion, including the resulting cracking of foundations, walls, floors and patios
- Earth movement, such as soil shrink-swell, subsidence and landslides
- Wear and tear, deterioration and poor maintenance
- Damage from groundwater and surface water, which falls under flood insurance
- Faulty design, workmanship or materials
In practice that covers the most common causes of foundation repair: expansive clay drying out in a Texas summer, a bowing basement wall pushed by wet soil in New Jersey, or a crawl space pier sinking over decades in Tennessee.
When a policy may pay
- A sudden covered event causes the damage. A falling tree, a vehicle hitting the house, fire or an explosion can damage a foundation, and those perils are typically covered.
- Sudden plumbing leaks, depending on the form. In Texas, the Texas Department of Insurance stated in Commissioner’s Bulletin B-0032-97 that the standard HO-B policy form covers damage to the dwelling, including the foundation, from accidental discharge or leakage of water from within a plumbing, heating or air-conditioning system. Many newer policies narrow or exclude this, so check your own form and endorsements.
- Collapse coverage. Some policies include limited coverage for abrupt collapse caused by specific perils. It rarely applies to gradual settlement.
- Endorsements. Some insurers sell endorsements for foundation or earth movement coverage. Availability varies by state and company.
Flood insurance and foundations
Flood damage is excluded from standard homeowners policies and covered through separate flood insurance, such as the National Flood Insurance Program. FEMA’s NFIP summary of coverage lists foundation elements and anchoring systems as covered building property for direct physical flood damage. The same program does not cover damage caused by earth movement, even if the earth movement was caused by a flood. That distinction is a common source of disputes after hurricanes in Houston, the Coastal Bend and Southwest Florida.
Sinkholes: Florida is different
Florida law requires every insurer that sells property insurance in the state to cover catastrophic ground cover collapse: an abrupt collapse of the ground, a depression visible to the naked eye, structural damage to the building including the foundation, and the structure being condemned and ordered vacated. Broader sinkhole loss coverage must be offered for an additional premium and may carry a deductible of 1, 2, 5 or 10 percent of the dwelling limit. Outside Florida, sinkhole coverage is usually excluded under earth movement unless you buy an endorsement. See our guide on sinkholes and foundations.
Common scenarios at a glance
| Situation | Typical outcome under a standard policy* |
|---|---|
| Slab settles after a dry summer on expansive clay | Usually excluded (settling, earth movement) |
| Basement wall bows from soil and water pressure over years | Usually excluded (earth movement, wear and tear) |
| A tree falls on the house and cracks the foundation | Often covered as a sudden, accidental event |
| A pipe under the slab bursts suddenly | Depends on the form; some policies cover resulting damage, many limit or exclude it |
| A slow leak under the slab goes unnoticed for months | Often excluded as continuous or repeated leakage |
| Floodwater damages the foundation | Excluded under homeowners; flood insurance may cover direct flood damage but not earth movement |
| Sinkhole in Florida | Catastrophic ground cover collapse covered by law; broader sinkhole loss only if purchased |

How to read your own policy
- Find your declarations page and note the policy form (for example HO-3, HO-5, or in Texas HO-A, HO-B or a company form).
- Read the exclusions section for “settling,” “earth movement,” “water damage” and “wear and tear.”
- Look for endorsements that add or remove coverage, such as water backup, foundation or sinkhole endorsements.
- Check how the policy treats plumbing leaks: sudden and accidental versus continuous or repeated leakage.
- Ask your agent in writing if anything is unclear.
The Texas Department of Insurance publishes a homeowners worksheet that lists common coverages and exclusions to compare policies line by line.
If you think a claim applies
- Document everything: photos of cracks with a ruler, doors that stick, water bills if you suspect a leak.
- Stop ongoing damage where you safely can, for example shut off a leaking supply line.
- Notify your insurer promptly; late notice can hurt a claim.
- Get a written cause-and-origin opinion from an engineer, not only a repair quote.
- Keep copies of the adjuster’s report and the policy language they rely on.
Questions to ask your agent
- Which policy form do I have, and which exclusions apply to foundation damage?
- How does my policy treat a sudden plumbing leak under the slab, and damage to the foundation caused by it?
- Does my policy cover the cost of accessing and repairing a leaking pipe, and is there a separate limit?
- Is an earth movement, foundation or sinkhole endorsement available in my state, and what would it cost?
- Do I need separate flood insurance at this address?
If insurance will not pay
Most foundation repairs are paid out of pocket. Getting two or three detailed quotes, comparing price per pier or per anchor, and asking about transferable warranties helps keep the cost in check. Our cost guide lists typical ranges by method, and the regional pages cover local prices, for example in San Antonio, Dallas and North Jersey.
Repairs are also worth documenting carefully for resale. Many states require sellers to disclose known foundation problems and repairs, and a permit, an engineer’s letter and a transferable warranty usually reassure buyers. See buying a house with foundation problems.
