Does Homeowners Insurance Cover Mold in Texas?

The Sudden Versus Gradual Distinction

Most Texas policies cover mold that results from a sudden, accidental, covered event — a pipe bursting, a water heater failing, a storm opening the roof. The mold is treated as a consequence of the covered water loss.

What policies generally exclude is mold from gradual or ongoing conditions: a slow leak under a sink for two years, chronic humidity, poor maintenance, or seepage through the foundation. The insurer's position is that these were preventable through reasonable upkeep.

Flood Is Separate

This catches Katy homeowners constantly. Standard homeowners policies do not cover flood. Rising surface water requires separate flood insurance, typically through the NFIP or a private flood carrier.

If your mold came from a flood event and you have no flood policy, the homeowners carrier will almost certainly deny it. If you do have flood coverage, mold resulting from the flood may be addressed under that policy, subject to its own terms and limits.

What Actually Decides the Outcome

The Texas History Behind Your Policy

Texas was the epicenter of mold insurance litigation in the early 2000s. The fallout reshaped the market: carriers added mold exclusions, capped mold coverage at low sublimits, and in some cases stopped writing certain coverage entirely.

This is why your policy may have a mold sublimit of ten thousand dollars or less even though your dwelling coverage is several hundred thousand. Read the mold endorsement specifically — do not assume the dwelling limit applies.

What To Do the Day It Happens

Stop the water. Photograph everything before you move or dry anything. Call your carrier and get a claim number. Start extraction and drying immediately, and keep receipts.

Adjusters evaluate the gap between discovery and response as closely as they evaluate the damage. Fast documented action is the strongest thing in your favor.
