Does Homeowners Insurance Cover Water Damage in Texas?

If your home has water damage, the first question is usually whether insurance will pay for it. In Texas, the answer depends almost entirely on how the water got there: whether it arrived suddenly, whether it came from outside as a flood, and whether it came back up through a drain. This guide covers what the Texas Department of Insurance (TDI) says about each situation, but it is general, informational content, not legal or insurance advice. Your specific policy language controls your claim, so confirm details with your agent, your insurer, or an attorney if a claim is disputed. The same Texas rules apply whether you’re filing a claim in Tyler or working with an insurer serving Longview.

Sudden and accidental vs. gradual damage

TDI describes the core coverage test in plain terms: most homeowner and renters policies cover water damage that is sudden and accidental, like a pipe that bursts or a washing machine hose that fails without warning. What those same policies typically will not cover is water damage from a gradual leak or seepage, meaning water that has been slowly leaking or seeping in over time.

In practice, this means the same amount of water damage can be covered or denied depending on the story behind it. A supply line that splits open overnight and floods a bathroom is a textbook sudden and accidental claim. A slow drip under a sink that went unnoticed (or unaddressed) for months, and eventually rotted the cabinet floor, usually falls under the gradual damage exclusion, even though the homeowner did not intend for it to happen. Insurers may investigate how long the water was present, sometimes using signs like staining, warping, or mold growth, to decide which category a claim falls into.

What’s typically covered, at a glance

Cause of water damage	Usually covered?	Notes
Burst pipe or failed appliance hose	Yes	Sudden and accidental
Gradual leak or seepage over time	No	Poor maintenance is treated differently than an accident
Flooding (rain, overflowing river, storm surge)	No	Needs a separate NFIP or private flood policy
Sewer or drain backup, sump pump failure	No, unless endorsed	Needs a water backup endorsement added before the loss
Mold from a covered sudden event	Often, up to a sublimit	Mold from a gradual leak or flood is excluded

The flood exclusion

A standard homeowners policy in Texas excludes flood damage, whether the water comes from heavy rain, an overflowing creek or river, or storm surge. The Texas Department of Insurance is explicit about this exclusion, and notes it is the fact that catches the most homeowners off guard. Coverage for flooding has to be purchased separately, either through the National Flood Insurance Program (NFIP) or a private flood insurer.

TDI also points out that flood risk in Texas is not limited to homes near a river or in a mapped flood zone. More than half of the homes flooded during Hurricane Harvey were outside any officially designated flood zone. Most flood policies carry a 30-day waiting period before coverage begins, so it needs to be in place well before a storm, not purchased in response to one. See our flood cleanup page for more on flood risk in the Tyler-Longview area and what cleanup involves.

Sewer and drain backup

A standard homeowners policy generally does not cover water or sewage that backs up through a sewer line, a floor drain, or a sump pump failure. This is a separate gap from both the sudden/gradual test and the flood exclusion; it is its own named exclusion in most policies. Coverage for this specific risk is usually available as an add-on, often called a water backup or sewer backup endorsement, and it is added to the policy before any problem happens, not after. If a backup has already occurred, see our sewage cleanup page for what that cleanup involves.

Mold coverage limits

Mold coverage under a Texas homeowners policy typically follows the source of the water that caused it. If mold grows on an item or a wall because of a sudden, covered water event, such as a burst pipe you addressed promptly, the resulting mold damage is generally covered as part of that claim. If the mold grew because of a gradual leak, or because of flooding, it is generally excluded along with the water damage that caused it.

Even when mold is covered, many policies apply a separate, lower coverage limit specifically for mold cleanup, sometimes a few thousand dollars regardless of your overall dwelling coverage. If you are dealing with mold after any kind of water event, ask your insurer directly what your mold sublimit is before assuming your full policy limit applies. Our mold cleanup page covers what remediation typically involves.

Texas homeowners policy forms

Most Texas homeowners policies today are written on the ISO HO-3 special form. Older Texas-specific forms, HO-A and HO-B, are also still found in the market. Because these forms vary by insurer and by endorsement, the only way to know exactly what your policy covers is to read your declarations page and policy form, or ask your agent to walk through it with you.

Form	Dwelling coverage	Personal property	Claim settlement
HO-3 (most common today)	Open perils (covered unless excluded)	Named perils only	Usually replacement cost
HO-B (older Texas form)	Broader named perils	Named perils	Varies by insurer
HO-A (oldest, most limited)	Named perils only	Named perils only	Often actual cash value (replacement cost minus depreciation)

Claim steps and deadlines

Texas’s Prompt Payment of Claims Act sets deadlines for how an insurer has to handle your claim once you file it. These are the outer deadlines set by state law, not a guarantee of how fast a specific insurer will move; always check the timelines in your own policy too.

Step	Standard deadline	Surplus lines insurer
Acknowledge claim, start investigating	15 calendar days	30 business days
Decide if claim is “clean” or needs more documentation	30 days (electronic) / 45 days (non-electronic)	Same
Pay once the claim is payable	5 business days	20 days
Interest owed if payment is delayed past 60 days	18% annual interest plus attorney’s fees	Same

Documenting the damage

Before any cleanup or repair starts:

1. Photograph and video the damage, including standing water, wet materials, and the visible source of the leak.
2. Keep a list, with photos, of damaged personal property such as furniture, electronics, or spoiled food.
3. Save receipts for any emergency repairs or temporary lodging tied to the claim.

Good documentation upfront speeds up the claims process and gives you something concrete if the claim is ever disputed, and it lines up with how water damage restoration in East Texas usually starts anyway, since a company will want to see the damage before drying begins.

Your duty to mitigate

Texas policies generally expect you to take reasonable steps to prevent further damage once you discover a problem, such as shutting off the water main after a burst pipe or moving valuables out of a flooded room. An insurer can potentially deny or reduce the portion of a claim tied to damage that happened after you knew about the problem and failed to act. This does not mean you are expected to perform repairs yourself, only that you should stop the immediate source of loss when it is safe to do so.

Working with adjusters

An adjuster’s job is to evaluate the cause and extent of the damage against your specific policy language. It is reasonable to ask the adjuster which exclusion or coverage they are applying and why, to request a copy of the relevant policy section, and to get any denial in writing. If a restoration company’s estimate differs from the adjuster’s estimate, ask for a line-by-line explanation of the difference rather than accepting either number without review.

If you have a complaint

If you cannot resolve a coverage dispute directly with your insurance company or agent, you can file a complaint with the Texas Department of Insurance through its online complaint system. TDI will contact the company and require a response, generally within 15 days, with a possible 10-day extension. You can also call the TDI Consumer Help Line at 800-252-3439 with general questions about a policy or a claim.
