Storm and flood damage in Dallas: costs, insurance and safe cleanup

Storm and flood losses are usually the largest water damage jobs, because water arrives from outside, often carries mud and contamination, and can reach many rooms at once. These national ranges come from published cost guides; Dallas-specific figures are not published by any agency.

Whether insurance pays depends on how the water got in. That question, wind and rain through a damaged roof versus rising water from outside, decides which policy applies.

No, and this matters for the scope and the price. The ANSI/IICRC S500 standard lists rising water from rivers or streams and all forms of flooding from seawater among its examples of Category 3, grossly contaminated water. But in a February 2026 position statement, the S500 Consensus Body stated that top-down water ingress, wind-driven rain and water from weather-related events are not automatically Category 3. The restorer is expected to inspect, gather information and make a preliminary determination based on whether the water is actually grossly contaminated.

In practice: water that rose from a creek or street flooding into your house is a strong Category 3 candidate. Rain that came through a roof opening may be cleaner. Ask the company how it decided and get the reasoning in writing, because Category 3 means more removal, containment and cost.

1. Stay out of moving water. The National Weather Service says 6 inches of fast-moving flood water can knock over an adult and 12 inches of rushing water can carry away most cars. Turn around, don't drown.
2. Make sure the power is off before entering a flooded area. The EPA warns that standing water can create a shock hazard if outlets are wet, and that a building with signs of structural damage, such as a sagging roof, should be treated as unsafe.
3. If you smell gas, leave and call 911 from a safe place. You can also call the emergency line printed on your gas bill. Our emergency checklist lists the Atmos Energy emergency contact.
4. Protect yourself during cleanup with boots, long pants, work gloves, eyewear and a respirator, as the Red Cross recommends, because floodwater may carry sewage and chemicals.
5. Document and mitigate. The Texas Department of Insurance says to report damage as soon as possible, take pictures and video, make temporary repairs such as covering holes, remove standing water, and keep receipts.

Our emergency checklist covers these steps in more detail.

Usually not. The City of Dallas floodplain management page states that homeowners policies do not cover damage from floods, that flood policies are available to everyone, including previously flooded properties, and that there is a 30-day waiting period. Under the National Flood Insurance Program, FloodSmart says building coverage goes up to $250,000 and contents coverage up to $100,000, and any homeowner in a participating community is eligible.

To check whether your property is in a mapped flood zone, the city points to the Dallas Central Appraisal District site with the FEMA flood zone layer, the city's zoning GIS site and FEMA's website, and notes these give only an estimate. The city also runs a Flooded Roadway Warning System and maintains the levees and pump stations of the Dallas Floodway along the Trinity River, according to its Stormwater Operations page. Suburbs manage their own floodplains, so check with your city. Our insurance claim guide explains the claim process.

• Watch for door-to-door offers. The Texas Attorney General warns that door-to-door contractors flock to neighborhoods after disasters, and to be suspicious of low-ball estimates and anyone who will not leave a contract overnight.
• Know the payment rules. The Attorney General says special laws apply to contractors from another area working because of damage; they generally may not require payment before beginning work.
• Use your cancellation right. For sales made at your home, the contract must include a notice giving you three business days to cancel, according to the same page.
• Never sign a contract with blanks, and walk away from anyone offering to waive your deductible, which the Texas Department of Insurance says is against the law.
• Check licenses that apply: TDLR for mold and TSBPE for plumbing. See mold remediation.
