Does Insurance Cover Mold? Texas Homeowners Guide (2026)

TDI's consumer FAQ puts it plainly: "Most homeowner and renters policies cover sudden and accidental water damage," such as a burst pipe, toilet overflow or broken washer hose, and "if mold develops on a damaged item, it would be covered." The same page says policies "usually won't cover damage from gradual leaks," and that "mold from a flood would not be covered because home policies don't cover floods."

So the question an adjuster asks is: what caused the water, and how long was it going on?

Sudden vs. gradual water damage

"Sudden and accidental" is the phrase that decides most mold claims. TDI's home insurance guide lists "sudden and accidental release of water or smoke" among the risks most policies cover, and "a continuous water leak" among the things they don't.

Many insurers also put a clock on it. A TDI comparison of Texas policies shows some forms exclude leakage that lasted 14 or more days, others leakage over "weeks, months, or years," and others leakage that continued long enough to cause rot or deterioration. That is why a slow drip under a sink that rotted the cabinet floor over months is usually denied, while the same sink line bursting on a Tuesday is usually paid.

TDI also warns that hidden water damage usually must be reported within days of when you first see it. Waiting can turn a covered loss into a denied one.

Often not, even when the leak itself is covered. This is the part that surprises people.

TDI's home insurance guide says most policies "won't cover mold removal, except to repair damage caused by a covered risk," and that mold removal can be added as an endorsement. Its water and mold tip sheet adds that most home policies don't pay for mold cleanup and testing after a damaged item is removed, though insurers may let you buy that coverage.

In practice, that means a covered burst-pipe claim may pay to replace the soaked drywall and flooring, but not for a remediation crew to contain and clean the mold, or for an assessor to test afterward, unless you bought the add-on. Read the mold section of your policy and any endorsement page before you call a contractor. If you need a price range for the work itself, see our mold remediation cost guide.

Texas has stricter mold language than many states for a reason. In 2001, TDI's commissioner found that over the 18 months ending June 30, 2001, mold claims per 1,000 policies rose from 1.6 to 10.8, "more than sixfold," and the average mold claim was about $18,000, 4.7 times the average homeowners claim. Nueces County (Corpus Christi) had the highest claim rate in the state.

The commissioner's order, CO-01-1105, narrowed mold coverage in the state's standard forms:

• Basic coverage stayed only for mold that follows a "sudden and accidental discharge, leakage, or overflow of water or steam," and hidden losses had to be reported within 30 days of when they were or should have been found.
• Remediation and testing were not covered by the basic coverage.
• Optional "buy-back" endorsements let homeowners buy back mold coverage at 25%, 50% or 100% of the dwelling and personal property limits.
• The new rules became available January 1, 2002, and were mandatory by January 1, 2003.

Since 2003, insurers can file and use their own policy forms instead of the Texas standard forms, so the exact mold wording now varies by company. The 2001 order explains the history, but your current policy is what counts.

Texas policies still get described using the old state form names. TDI's comparison maps them like this:

The key point: even the broadest form excludes mold except, as TDI puts it, the "necessary costs to repair or replace property damage caused by a covered water loss." An HO-A policy is narrower still, since water damage is only covered if it is one of the named perils. If you aren't sure which type you have, the declarations page or your agent can tell you.

For Gulf Coast homeowners, this distinction matters most. Most home policies don't cover damage caused by floods, so mold after rising water needs a flood policy, either from your insurer or the National Flood Insurance Program (NFIP). TDI notes flood policies often have a 30-day waiting period, so buy before a storm is in the Gulf.

Flood insurance doesn't solve the mold question by itself, either. FEMA says NFIP flood policies "will not cover damage from mold," with possible considerations only when officials banned entry to the area or floodwater kept you from getting in to clean up. In other words, the flood policy pays for flood damage, and you are expected to dry out and remove wet materials fast. Our guide to mold after a flood in Texas walks through those first 48 hours.

People searching "mold remediation insurance" usually mean one of two things.

1. Mold coverage on your homeowners policy. This is the endorsement or buy-back coverage described above. Ask your agent for the mold limit in dollars and whether it covers remediation and testing.
2. The insurance a remediation company carries. Texas requires licensed mold assessors and remediators to carry commercial general liability insurance of at least $1 million per occurrence under TDLR rules (16 TAC § 78.40). Ask any company for its certificate of insurance before work starts.

TDI's guidance boils down to a few steps:

1. Stop the water and dry fast. TDI says to stop the water, remove standing water and dry the area quickly, since mold can start within a day. TDI also warns your insurer may deny a claim if you don't protect your property.
2. Report it promptly. Tell your company as soon as possible. Some policies have a one-year deadline unless you show good cause.
3. Photograph before you fix. Take photos or video of the damage before repairs, and keep damaged items until the adjuster sees them.
4. Make only temporary repairs and keep every receipt.
5. Use licensed mold pros. TDI says to make sure the mold professional holds a state license, and that you'll need an inspection showing the mold was removed and the cause fixed. You can confirm any license with our Texas mold license check.

Texas law also sets deadlines for the insurer. A company must acknowledge your claim and start investigating within 15 days of notice, then accept or reject it within 15 business days of getting everything it asked for, or explain why it needs more time (up to 45 days). A rejection must state the reasons in writing.

After licensed remediation, Texas law requires the remediation license holder to give the property owner a certificate of mold remediation within 10 days of finishing. A licensed mold assessor must sign a statement that the mold was remediated according to the protocol, and note whether the underlying cause was fixed.

The certificate is TDI form PC326 MDR-1. Box A is signed by the remediation contractor, Box B by the mold assessment consultant. The form itself tells owners to "keep this certificate and give a copy to your insurance agent or company."

It matters in two ways:

• Insurance. A Texas insurer may not make an underwriting decision based on previous mold damage or a mold claim if the property was remediated and a certificate shows the underlying cause was fixed, or an independent assessor or adjuster found no evidence of mold damage. Without that paperwork, a past mold claim can follow the house.
• Selling your home. If you sell, you must give the buyer a copy of every certificate issued for the property in the past five years.

Because Texas law bars one license holder from doing both mold assessment and remediation on the same project, you'll hire two companies: a mold testing company to write the plan and sign off, and a separate mold removal company to do the work. Our guide on why testing and removal must be different companies explains the rule, and clearance testing covers the final sign-off.

Ask for the denial in writing (the insurer must state its reasons), compare it with the exact exclusion in your policy, and gather your photos, plumber's report and timeline. If you think the company broke the rules, TDI's Help Line (800-252-3439) can explain your options. For disaster-related lawsuits, TDI notes you must give written notice at least 61 days before suing.
