Does home insurance cover water damage and mold in Texas?

This guide explains how a Texas home policy may treat a burst pipe, a slow leak, mold and flood water, using Texas Department of Insurance (TDI) consumer guidance.

The short version. On home insurance in Texas, TDI's When are water damage and mold covered by insurance? says: "Most homeowner and renters policies cover sudden and accidental water damage." The same page says mold that develops on a damaged item would be covered, that policies usually won't cover damage from gradual leaks, that mold from a flood would not be covered, and that most home policies don't include mold cleanup and testing after a damaged item is removed. TDI's Home insurance guide words the flood point as most home policies not covering damage caused by floods, lists mold removal, except to repair damage caused by a covered risk, among the things most policies don't cover, and says coverages vary by company.

Here's what we'll cover: the difference TDI describes between sudden and gradual water damage, where mold fits, why TDI says most home policies don't cover floods, what mold cleanup coverage you may be able to add, and what TDI says to do after you find water.

Sudden vs. gradual water damage

Water damage coverage on a Texas home policy may turn on whether the water was sudden and accidental or a gradual leak. The examples of sudden and accidental water damage on TDI's water damage and mold page are a burst pipe, a toilet overflow and a broken washer hose.

The same TDI page gives the other half: "Policies usually won’t cover damage from gradual leaks."

TDI's Home insurance guide makes the same distinction in its table of common risks. It lists a sudden and accidental release of water or smoke among the risks most policies cover, and a continuous water leak among the risks most policies don't cover. The guide adds that coverages vary by company and suggests reading your policy or talking to your agent to be sure of your exact coverages.

The question on a water claim may be how the water got there and how long it took, as well as how much damage it did. Two losses that look alike on the surface can be treated differently if one came from a pipe that failed in a moment and the other from a fitting that leaked over a long period.

Where mold sits

Whether a Texas home policy covers mold may depend on the water that caused it. Right after saying most homeowner and renters policies cover sudden and accidental water damage, TDI's water damage and mold page continues: "If mold develops on a damaged item, it would be covered."

On gradual leaks, the same page says: "Most home policies don’t cover water damage from gradual leaks or seepage, and that includes damage from mold."

So mold on an item damaged by a washer hose that burst last night may be treated as part of that sudden loss. Mold from a shower pan that has leaked for two years may not be. A long-running leak like that may fall in the gradual-leak category TDI describes.

Mold removal is a second, narrower point. In the Home insurance guide, TDI's list of risks most policies don't cover says policies also won't cover mold removal, except to repair damage caused by a covered risk, and the guide notes that coverages vary by company. The water damage page adds: "Most home policies don’t include mold cleanup and testing after a damaged item is removed." Repairing what the water damaged, and cleaning up and testing the space afterward, can be two separate questions.

Most home policies don't cover floods, per TDI

Most home policies don't cover damage caused by floods, according to TDI's Home insurance guide, which lists flooding among the risks most policies don't cover and notes that coverages vary by company. TDI's water damage and mold page states it without that qualifier: "Mold from a flood would not be covered because home policies don’t cover floods." That page goes on to say you would need a separate flood policy.

The guide also suggests talking to your home insurance agent about a flood policy from your insurance company or the National Flood Insurance Program. It says most flood policies have a 30-day waiting period before they take effect, and advises against waiting for an approaching storm to decide. If flooding is a concern where you live, that waiting period is a reason to ask about flood coverage ahead of time.

The coverage you may be able to add

Mold cleanup coverage may be something you can add to a Texas home policy. According to TDI's water damage and mold page, your insurance company may let you add coverage for cleanup caused by a covered loss, and your agent can tell you what options are available.

The Home insurance guide describes endorsements as policy add-ons that let you increase or add coverage, and it includes mold removal in its list of common endorsements.

An endorsement changes what your own policy covers. Ask what your current policy does about mold cleanup and testing, and what adding that coverage would involve.

What TDI says to do after a leak

After a water leak in a Texas home, TDI's water damage and mold page advises drying the area as soon as you can, and says: "Mold can start growing within a day after a leak."

The page gives these tips to prevent more damage after a water leak or flood:

• Stop the water. Stop the water flow or leak as soon as you can, and know how to turn the water off at the main valve or at the valves under your sinks and near appliances.
• Start drying. Remove pools of water and start drying the area to prevent more damage and mold growth.
• Move wet items. TDI suggests a dry room or an area with fresh air, and pulling up wet carpets and rugs.
• Use a service if you need one. This tip applies if you can't remove the water and dry the area yourself.

For the claim itself, the page's first tip is to tell your company as soon as possible. It then adds: "You usually must report water damage that was hidden from view within days after you first see it."

The other claim tips on that page are to make a list of your damaged property, to take pictures or videos of the damage before making any repairs if possible, and to keep damaged items until your adjuster has seen them. It also says to make temporary repairs to protect your house and belongings, to hold off on permanent repairs until your insurance company sees the damage, and to keep receipts for any materials you bought to make repairs.

For a mold removal claim, the same page has three more tips. Make sure the mold professional has a state license, and expect to need an inspection showing that the mold was removed and that you fixed the problem that caused it. The third is about paperwork: "Mold professionals must provide a certificate that the mold was removed."

What to do with this

Start with the policy itself when you check water and mold coverage on a Texas home. TDI's Home insurance guide notes that coverages vary by company and suggests reading your policy or talking to your agent to be sure of your exact coverages.

• Find out what your policy says about water. TDI uses the words sudden and accidental, continuous and gradual; your policy's wording may differ.
• Ask about mold cleanup and testing. Ask whether your policy includes them and whether an endorsement is available. They are separate from repairing the damage itself.
• Handle the maintenance side yourself. Checking your plumbing from time to time can help you catch a slow leak early.
• Know where your main shut-off valve is. Knowing how to turn the water off is part of TDI's first tip for stopping a leak.
• If flooding is a concern, ask about flood coverage separately. TDI's guide says most home policies don't cover damage caused by floods.

If you're not sure whether your policy would treat a given loss as sudden or gradual, or whether you have any mold cleanup coverage, that's worth reading through with someone before you need the answer.
