Does insurance cover mold damage in Texas?

Mold coverage in Texas is more restricted than most homeowners realise, and the reasons are historical. A wave of very large mold claims in the early 2000s led insurers here to limit mold cover substantially, and the structure that emerged is still what you are buying today.

Water and mold are two separate questions

This trips people up more than anything else. A policy can cover the water loss and cover very little of the mold that followed it.

Water damage from a sudden and accidental discharge — a burst supply line, a failed water heater, an overflowing appliance — is typically covered under a standard Texas homeowner policy.

Mold is usually treated separately, often with a specific limit, and sometimes excluded unless you bought an endorsement. Where a limit exists it is frequently well below what a substantial remediation costs.

So the answer to "is my mold covered" is often: the water is, some of the mold is up to a cap, and the rest is yours.

Sudden and accidental versus gradual

The distinction that decides most claims.

Covered, typically: a pipe bursts during a freeze. A supply line to a toilet fails. A water heater lets go. A washing machine hose splits. These are discrete events with a date.

Not covered, typically: a shower valve that has been weeping for two years. A roof that has leaked slowly since the last hail. Condensation from an air conditioning system that has been dripping all summer. These are described in policies as continuous or repeated seepage, and they are excluded almost universally.

Here is the difficulty. The most common cause of mold in this region is air conditioning condensate, and it is gradual by nature. It wets a little every day for months. That is exactly the profile insurers exclude.

Which is not a reason to skip the claim. It is a reason to establish the timeline properly, because whether the wetting began with a discrete failure — a float switch that stopped working, a pan that cracked — or was simply slow deterioration, changes the answer.

What flood is, and why it is not in your policy

Worth stating plainly because it catches people every storm season.

Standard homeowner policies in Texas exclude flood entirely. Flood means water arriving from outside at ground level: rising creeks, sheet flow across the ground, storm surge. Cover for that requires a separate flood policy, and those typically carry a waiting period before taking effect.

Rain entering through a storm-created opening — wind removes shingles, rain comes through the hole — is usually covered under the homeowner policy as a wind claim.

The same storm can therefore produce two losses in one house, paid by two different policies or by one and not the other. The distinction is where the water came from, and it is established by evidence collected early: the height and direction of the waterline, debris deposits, the condition of the roof, and whether moisture is worst at ceiling level or floor level.

What to document on day one

This is the practical part, and it matters more than anything you do later.

• Photograph everything before you move it. Standing water, affected rooms, contents, and the failed component itself if you can see it.
• Record the waterline height against a wall with something for scale, if water came in at floor level.
• Note the date and time you discovered it and what you did in response.
• Keep the failed part where practical. A split section of pipe is evidence of a sudden failure.
• Get moisture readings taken professionally at the outset. A drying log with daily readings is what supports the scope you eventually claim.
• Keep receipts for everything, including anything you buy yourself in the first hours.

Mitigation is your obligation, not a favour to the insurer

Every Texas policy requires the insured to take reasonable steps to prevent further damage.

That means you should not wait for authorisation before starting emergency mitigation. Delay makes the loss larger, and a claim can be reduced where the damage grew because the insured did nothing.

Call the insurer, and call a restoration contractor, in whichever order gets water out of the building fastest.

The freeze claim question

Specific to this climate, and it decides large claims.

Texas policies generally cover burst pipes from freezing, conditional on the insured having taken reasonable care to maintain heat and protect the plumbing. A house left unheated and unattended during a hard freeze can see a claim reduced or denied on that basis.

So document that the heat was on: thermostat records, utility usage, a neighbour who checked the property. It is a small thing that decides expensive outcomes.

Sewer backup is usually a separate endorsement

Another one people discover at the worst moment. Cover for a sewer or drain backup is commonly an add-on rather than part of the base policy, and where it exists it usually carries its own sub-limit — often a few thousand dollars, which a full ground-floor loss will exceed.

Failure of your own septic system is frequently excluded entirely as a maintenance issue.

What to do before you need any of this

Read the declarations page, and specifically look for: the mold limit or exclusion, whether you have a sewer backup endorsement, whether you have flood cover, and what your water damage deductible is.

Then fix the gradual-damage causes that are excluded anyway. Clearing a condensate line and fitting a float switch costs very little and removes the most common uninsured loss in this region.
