Water damage claims in San Antonio are among the most common, and the most misunderstood, property insurance claims. Water can come from a burst supply line, a failed water heater in the garage or attic, an overflowing dishwasher, a roof opened by hail, or pipes that split during a freeze like Winter Storm Uri in February 2021. Whether the claim is covered usually depends less on how much damage there is and more on where the water came from, how suddenly it happened, and how long it went on before anyone noticed.
This page explains how insurers sort water losses, the exclusions that come up most often, and how a public adjuster in San Antonio may help. If the damage came from a hard freeze, see our freeze damage claims page as well.
Sudden and Accidental vs. Gradual Damage
Most homeowners and commercial policies cover water damage that is sudden and accidental, such as a supply line that bursts or a water heater tank that ruptures. Most exclude damage from continuous or repeated seepage or leakage over weeks or months, along with wear and tear, deterioration, and lack of maintenance. That single distinction drives many water damage denials.
| Source | Often covered? | Key condition |
|---|---|---|
| Burst supply line or pipe | Often | Sudden and accidental discharge |
| Frozen pipe | Often | Reasonable heat maintained, or water shut off and drained, per policy |
| Water heater, washer, or dishwasher failure | Often | Sudden failure, not long-term dripping |
| Roof leak after hail or wind | Often | The storm created the opening |
| Roof leak from age or wear | Usually not | Wear and tear exclusion |
| Slow leak over weeks or months | Usually not | Continuous or repeated seepage exclusion |
| Sewer or drain backup | Only with endorsement | Water backup coverage purchased |
| Rising water or surface runoff | Not under standard policies | Requires flood insurance |
The gray area is a hidden leak, for example a pinhole leak inside a wall that went unnoticed until the drywall softened. Some policies treat hidden leaks differently from visible ones the owner ignored. The wording of your policy and the evidence about timing both matter. If water entered from outside during heavy rain, the question shifts to whether it came through a storm-created opening or rose from the ground; see flood damage claims.
Common Water Losses Around San Antonio
- Attic plumbing and equipment. Many local homes have water heaters, air handlers with condensate lines, and supply lines in the attic. A failure there sends water through ceilings and insulation.
- Storm-related roof leaks. Hail and wind can open roofs during spring storms. See roof damage insurance claims.
- Freeze breaks. Pipes in attics and exterior walls are vulnerable during hard freezes.
- Slab leaks. Most homes here sit on slab-on-grade foundations over expansive clay soils. A leak under the slab can damage flooring and walls, but foundation movement and settling are commonly excluded.
- Appliance supply lines. Washing machine, refrigerator, and dishwasher lines can fail without warning.
- Commercial losses. Fire sprinkler discharges, rooftop unit leaks, and plumbing failures in multi-tenant buildings. See commercial property claims.
Water From the Utility Side
Most water damage claims involve plumbing on the owner's side of the meter. If you believe water came from a public main or from equipment on the utility side, contact SAWS about that issue directly; any process the utility has is separate from your property insurance claim. Your own policy still governs damage to your property, so report the loss to your insurer as well. A sudden jump on your SAWS bill can also help show when a leak on your side began. General information is available from SAWS.
Mold: Know the Limits
Mold is where many water claims run into trouble. Many Texas policies exclude mold or cap coverage at a set dollar amount, and some cover remediation only when mold results directly from a covered water loss. Mold that grew because of a long-term leak, or because drying was delayed, is often excluded. A public adjuster cannot make a mold exclusion disappear. What helps is prompt action: stop the water, start professional drying quickly, keep moisture readings, and document that you acted reasonably. If mold has already developed, separate the cost of mold remediation from the cost of the underlying water damage repairs, because they may be treated very differently under your policy.
Deductibles, Depreciation, and Limits
Water losses usually fall under your policy's all-other-perils deductible rather than the wind/hail deductible, unless the water came in through storm damage. Flooring, cabinets, and contents may be depreciated, with replacement cost released after repairs if your policy provides it. Some policies also set sublimits for specific water-related items. Our claim calculator shows how a deductible and depreciation affect what an insurer pays.
Documenting a Water Damage Claim
- Stop the water at the shut-off valve and photograph the source before repairs.
- Keep the failed part (supply line, valve, or pipe section) if a plumber removes it.
- Get a written plumber's report describing the cause of the failure.
- Hire a mitigation company promptly and keep moisture maps, photos, and drying logs.
- Photograph every affected room, including cabinets, baseboards, and flooring.
- List damaged contents with age and approximate cost.
Our claim documentation checklist walks through these steps in more detail.
How a Public Adjuster Can Help With Water Damage
San Antonio Public Adjuster represents policyholders on water damage claims. We may review your policy's water, seepage, mold, and access provisions, document the loss room by room, prepare a line-item estimate in Xactimate that includes access, tear-out, drying, and rebuild, and respond to insurer arguments about gradual leakage or wear and tear. If a water claim was denied, see denied insurance claims. If the claim was paid but the estimate left items out, we can review it for an insurance claim supplement.
We cannot guarantee a result; coverage depends on your policy and the facts. Fees are disclosed in a written contract before any work begins; Texas law caps public adjuster compensation at 10% of the insurance settlement. For legal questions about deadlines or disputes, consult a Texas attorney.
Frequently Asked Questions
Does homeowners insurance cover water damage from a burst pipe?
Many policies cover sudden and accidental discharge of water from a plumbing system, including a pipe that bursts. The cost to repair the pipe itself, and freezing in an unheated or vacant home, may be treated differently. Check your policy.
Is a slow leak under my sink covered?
Often not. Many policies exclude continuous or repeated seepage or leakage over time. Some provide limited coverage when the leak was hidden inside a wall or floor and you did not know about it. The exact wording controls.
Will insurance pay to find a hidden leak?
Some policies cover the cost to tear out and replace parts of the building to reach a covered leak, such as opening a wall or floor. The repair of the failed pipe or appliance itself is often excluded.
Will my insurer pay for mold?
Many Texas policies exclude or limit mold, sometimes covering remediation only when it results from a covered water loss and often with a dollar cap. Prompt drying is the best way to avoid a mold dispute.
Is water from heavy rain or a flooded street covered?
Standard homeowners and commercial policies generally exclude flood and surface water. That coverage comes from a flood policy. Rain that entered through a storm-damaged roof is different and may be covered. See flood damage claims.
How quickly should I start drying?
Right away. Policies require reasonable steps to protect the property from further damage. Keep the mitigation company’s moisture readings, photos, and drying logs.
Can my SAWS bill help my claim?
Sometimes. A sudden jump in water usage on your bill may help show when a leak began. Keep copies of recent bills along with your plumber’s report.
