Does Homeowners Insurance Cover Mold in Texas?

What does a typical Texas homeowners policy say about mold?

Texas policies treat mold as something that follows a covered water loss, not as a stand-alone risk. In its comparison of Texas homeowners policies, the Texas Department of Insurance (TDI) lists among common exclusions "mold, except necessary costs to repair or replace property damage caused by a covered water loss." It also notes that the building exclusions in HO-B and HO-C type policies typically include mold, fungus and rot, and that water damage from continuous and repeated leakage or seepage is a common exclusion.

TDI's consumer guidance boils it down. Most homeowners and renters policies cover sudden, accidental water damage, such as a burst pipe, a toilet overflow or a broken washer hose, and if mold develops on an item damaged by that covered event, the mold is covered too. Most home policies do not cover water damage from gradual leaks or seepage, including the mold that results. Mold from a flood is not covered either, because home policies exclude floods.

Common Houston scenarios and how they usually play out

Policy wording varies by company, so treat the table as a starting point, not a coverage decision. The time limit matters: one TDI example of limited water coverage excludes leakage from plumbing, heating, air conditioning or sprinkler systems that went on for 14 or more days. In many Houston homes the AC equipment sits in the attic, where a slow condensate leak can go unnoticed, which is why AC mold in Houston homes is often a maintenance question rather than an insurance one.

Can you buy more mold coverage?

Sometimes. TDI says some companies let you buy full or limited coverage for excluded perils, and it lists mold remediation as one example. Its consumer guidance also says your insurer may let you add coverage for cleanup caused by a covered loss. Ask your agent what is available, what the limit is, and whether testing and clearance are included, since post-remediation testing is a required step on Texas jobs and has its own cost.

What should you do the day you find water damage?

1. Stop the water. TDI suggests shutting off the main valve or a nearby valve as soon as possible.
2. Start drying right away. TDI notes mold can start within a day; EPA advises drying wet materials within 24 to 48 hours.
3. Document before repairs. Make a list and take photos or video, and keep damaged items until the adjuster has seen them.
4. Make temporary repairs only. Tarps or boarded windows are fine; hold off on permanent repairs until the insurer inspects, and keep receipts.
5. Report promptly. TDI says that for hidden water damage you generally must report within days of first seeing it. The Attorney General's mold page notes that policies may set a reporting window, typically 30 days.

If the mold is behind a wall or under flooring, a Houston mold inspection can map how far it goes before anyone starts tearing out materials, which also gives the adjuster a clear record. When the damage is inside wall cavities, see our page on mold in walls in Houston homes.

What does the insurer expect on a mold claim?

TDI tells consumers to make sure the mold professional has a state license, to expect an inspection showing the mold was removed and the cause was fixed, and to get a certificate that the mold was removed. In Texas that certificate is the Certificate of Mold Damage Remediation (CMDR). The remediation contractor must deliver it, with before-and-after photos, within 10 days after the project ends, and it carries the assessment consultant's statement that the work followed the protocol.

You choose the companies. The Attorney General notes that some insurers keep lists of recommended mold specialists, but the choice of contractor is yours. Remember that Texas law requires one company to assess and a different company to remediate on the same project, and both should show up on TDLR's license search. Our guide to vetting a Texas mold company walks through those checks. The Attorney General also suggests reviewing all bids with your insurer to see which costs will be covered, and notes that filed claims can appear in the CLUE database used by insurers and in home sales.

Does the CMDR help with future insurance?

It can. Under Texas Insurance Code 544.303, as TDLR explains it, a CMDR for residential property can help keep an insurer from making an adverse underwriting decision based on previous mold damage or claims. It does not guarantee coverage or a premium. If you cannot get a CMDR, for example because the original work was done by people without a TDLR mold license, TDLR says you may get a certification from a mold assessment consultant or an adjuster. When you sell, you must give the buyer every CMDR issued for the property in the five years before the sale.

What about flood damage and mold?

Houston Public Works reminds residents that a standard homeowners policy does not cover flood, and that flooding is possible outside the mapped 1 percent annual chance floodplain. Flood coverage comes from a separate policy, usually through the National Flood Insurance Program. FEMA says it will not cover mold damage if a policyholder fails to act to prevent mold from growing and spreading, and a 2022 FEMA appeal decision cites the exclusion for mold resulting from failure to inspect and maintain the property after a flood recedes. Our guide to mold after flooding in Houston covers the first 48 hours and the flood claim deadline. If you need hands-on help, independent companies handle flood mold removal across Houston.

What does mold work cost if insurance does not pay?

Angi's Houston cost data reports that mold removal averages $2,016, with most jobs between $863 and $3,329. Inspection and testing average $453 in the same data. HomeGuide's 2026 national ranges put a bathroom at $500 to $2,000 and HVAC or duct work at $2,000 to $10,000. Because Texas requires two companies, the assessment and clearance are a separate bill from the removal. Our Houston mold cost breakdown explains what pushes a job up or down.

What if you rent, or still have questions?

Renters insurance generally follows the same sudden-versus-gradual logic for your belongings, but repairs to the unit are usually the landlord's job under Texas Property Code 92.052 once you give proper notice. Our guide for renters with mold in Houston covers the steps. For coverage questions about your own policy, TDI's help line is 800-252-3439. Homeowners in nearby towns such as Pearland follow the same state rules.
