The short answer
Texas homeowners insurance usually doesn’t pay to repair a foundation that moved because the soil shrank or swelled. It may pay when a sudden plumbing leak caused the movement, and some policies carry a foundation endorsement that broadens coverage for leaks.
Everything below depends on your own policy. Texas insurers have filed and used their own homeowners forms since 2003, so two neighbors with different companies can have different coverage. Read the exclusions and the endorsements page before you assume either way.
Covered and not covered, in general
| Cause of foundation damage | Usually covered? | Why |
|---|---|---|
| Clay shrinking in a drought, settling over time | No | Settling, cracking and earth movement are standard exclusions |
| Clay swelling after rain (heave) | No | Same exclusions; it’s soil movement |
| Tree roots drying the soil | No | Soil movement and maintenance |
| A sudden, accidental plumbing leak under the slab | Often, at least in part | The leak is a covered peril; Texas courts have held the settling exclusion doesn’t block it under the HO-B form |
| A slow leak that ran for months | Often not | TDI says companies don’t cover continuous or repeated seepage beyond a set period |
| Movement on a policy with a foundation endorsement | Depends on the endorsement | It may add leak-caused foundation damage, up to a cap |
Why soil movement is excluded
Homeowners policies are written to cover sudden events, and soil movement is slow and expected in clay country. The Texas Department of Insurance’s homeowners guide lists earth movement in its column of damages most policies don’t cover. Its consumer page on all-risk and named-peril policies adds that all-risk policies usually don’t pay to repair a home’s foundation.
The policy language has been consistent for decades. The 1991 Texas Standard Homeowners Policy, Form HO-B, excluded loss caused by settling, cracking, bulging, shrinkage or expansion of foundations, walls and floors. TDI’s 2002 order on the ISO HO 00 03 form says that form doesn’t cover settling, shrinking, bulging or expansion of foundations either. Nationally, the Insurance Information Institute says most property policies exclude earth movement.
The plumbing-leak exception
The exception comes from how the HO-B form treated water. Its accidental discharge coverage included the cost of tearing out and replacing any part of the building needed to repair the plumbing, and said the settling exclusion didn’t apply to loss from that peril. TDI took the position in a 1997 bulletin that foundation settling or cracking caused by an accidental plumbing discharge was a covered loss under the HO-B. The Texas Supreme Court agreed in its Balandran decision in 1998.
Two limits matter:
- Sudden, not slow. TDI’s 2018 handout says companies cover sudden and accidental discharge, but not continuous or repeated seepage beyond a set period. A leak that dripped for a year may fall outside coverage.
- Your form, not the old one. Many insurers no longer use the HO-B. Check how your policy words the accidental discharge coverage and its exclusions.
Foundation endorsements
TDI’s homeowners guide lists damage to foundations or slabs among the common endorsements, add-ons that extend a policy. Under the ISO forms approved for Texas, a Foundation Coverage-Texas Endorsement covers settling, cracking and expansion of foundations caused by leaks from plumbing, heating, air conditioning or sprinkler systems, including tear-out to repair the system. TDI’s order caps it at 15% of the dwelling (Coverage A) limit.
If you’re buying or renewing a policy on a Collin County house, it’s a fair question for your agent: does this policy have a foundation endorsement, what does it cover, and what does it cost?
If you think a leak damaged your foundation
- Report it promptly. TDI advises telling the insurer as soon as possible; some policies set a filing deadline of one year unless there’s good cause.
- Stop the leak, but hold off on permanent repairs. TDI warns an insurer may deny a claim if you make permanent repairs before it sees the damage. Temporary fixes to prevent more damage are different; keep receipts.
- Get the leak documented. A licensed plumber’s leak detection report, with the location and type of leak, is the core of the claim.
- Get the foundation documented. A floor elevation survey and photos show what moved and where. An independent engineer’s report can connect the leak to the movement, which is often the disputed point.
- Ask what’s covered beyond the pipe. Tear-out to reach the leak, foundation repair and cosmetic repairs may be treated differently.
The inspection page explains what a contractor’s inspection and an engineer’s report each give you.
What this means for your budget
For most Collin County houses, foundation repair is a homeowner expense, not an insurance one. Plan for it like a roof: keep the soil around the house evenly moist, fix leaks fast, and get an inspection when the signs appear. The cost page shows typical prices, and if you’re selling, the selling guide covers what to disclose.
