Texas homeowners insurance covers sudden and accidental water damage from internal sources such as burst pipes, appliance failures, and sudden roof leaks, but does not cover flooding from external sources like bayou overflow, storm surge, or overland flooding. Flood coverage requires a separate NFIP policy. Houston homeowners should be aware of hurricane deductibles, typically 1% to 5% of insured value, which apply to losses from named tropical storms and can represent thousands of dollars in out-of-pocket costs. The Texas Department of Insurance regulates the claims process and requires prompt payment with penalties for delays. Homeowners have the right under Texas law to choose their own contractor regardless of insurer recommendations. A sewer backup endorsement is strongly recommended for Houston homeowners given the frequency of drainage system overwhelm during rain events.
Does Homeowners Insurance Cover Water Damage in Houston?

Quick Answer: Yes, homeowners insurance in Texas covers sudden and accidental water damage from internal sources like burst pipes, appliance failures, and sudden roof leaks. It does not cover flooding from external sources (bayous, storm surge, overland flooding), gradual leaks, or maintenance-related damage. Separate flood insurance through FEMA's NFIP is required for flood coverage.
Before Hurricane Harvey, I thought my homeowners insurance covered flood damage. It did not. I learned that lesson in the most expensive way possible. The distinction between water damage and flood damage is not just semantics; it determines whether your claim is paid at all. Texas has its own insurance code, its own regulator (the Texas Department of Insurance, or TDI), and Houston homeowners face unique exposures including hurricane deductibles and mandatory flood insurance requirements in FEMA-designated flood zones. This guide explains exactly what your homeowners policy covers, what it does not cover, and what you need to know before your next rain event.

What Texas Homeowners Insurance Covers for Water Damage
Under Texas Insurance Code, homeowners policies must cover sudden and accidental water damage. The key word is sudden. If a pipe bursts at 3 a.m. and floods your kitchen, that is covered. If a pipe has been slowly leaking inside a wall for six months and eventually causes damage, that is generally not covered because it is considered a maintenance issue the homeowner should have discovered and addressed. The Texas Department of Insurance maintains a consumer guide to homeowners coverage that spells out these standards.
- •Burst or frozen pipes: covered under standard homeowners policy
- •Water heater failure or rupture: covered
- •Washing machine or dishwasher supply line failure: covered
- •Sudden roof leak from a storm: covered
- •AC unit condensate overflow (sudden): often covered
- •Water damage to neighboring unit caused by your plumbing: typically covered under liability
What Texas Homeowners Insurance Does NOT Cover
Exclusions matter as much as coverage. Texas homeowners policies uniformly exclude certain water-related losses, and understanding these exclusions is critical for Houston homeowners.
- •Flooding from external sources (bayou overflow, storm surge, overland flooding): not covered; requires NFIP flood insurance
- •Gradual leaks or seepage: not covered if the damage developed over time
- •Ground seepage through foundation: not covered under standard policies
- •Sewer or drain backup: not covered unless you have added a sewer backup endorsement (typically $50 to $150 per year)
- •Negligent maintenance: if a known problem was left unaddressed
- •Mold resulting from long-term moisture problems: often excluded or limited
Hurricane Deductibles: A Critical Houston Consideration
Texas homeowners in coastal counties and many inland counties face hurricane deductibles that are separate from and higher than the standard policy deductible. These deductibles typically range from 2% to 5% of the insured value of the home, not a flat dollar amount. On a $400,000 home, a 2% hurricane deductible means $8,000 comes out of your pocket before insurance pays anything. A 5% deductible means $20,000. This applies to any loss resulting from a named tropical storm or hurricane, even if the primary damage is from wind-driven rain rather than flooding.
- •Hurricane deductibles apply in most Houston-area counties
- •Typical range: 1% to 5% of insured dwelling value
- •On a $350,000 home at 2%: $7,000 deductible
- •On a $350,000 home at 5%: $17,500 deductible
- •Deductible applies when a named storm is within a specific distance of your area
- •Check your declarations page for your specific hurricane deductible percentage
- •TDI requires insurers to clearly disclose hurricane deductibles in policy documents
The Sewer Backup Endorsement: Why Houston Homeowners Should Have It
Houston's drainage system is routinely overwhelmed during heavy rain events. When storm drains back up, they often push water back through the sewer lines connected to homes. This type of damage, water coming up through floor drains, toilets, or sinks due to sewer backup, is not covered under a standard homeowners policy. You need a sewer backup endorsement, sometimes called a water backup and sump overflow endorsement. In Houston, where heavy rain events occur multiple times per year, this endorsement is worth the relatively modest premium.
- •Cost of endorsement: typically $50 to $200 per year
- •Coverage provided: $5,000 to $25,000 depending on the policy
- •Covers: water that enters through sewers, drains, or sump pump failure
- •Does not cover: flooding from external sources (that is still flood insurance territory)
- •Houston flooding events commonly cause sewer backup even in areas that did not directly flood
Texas Department of Insurance (TDI) Protections for Homeowners
Texas has some of the most homeowner-friendly insurance regulations in the country in certain areas. The Texas Department of Insurance provides oversight and has established rules that protect policyholders during the claims process. Understanding your rights under Texas law can make a significant difference in how your claim is handled.
- •15-day acknowledgment rule: your insurer must acknowledge your claim within 15 days
- •15-day acceptance or rejection rule: insurer must accept or reject the claim within 15 business days of receiving all requested information
- •5-day payment rule: insurer must pay within 5 business days of notifying you of acceptance
- •Prompt payment penalties: if insurer violates these deadlines, they owe 18% annual interest plus attorney fees
- •Right to choose your own contractor: Texas law protects your right to select your own licensed contractor
- •TDI complaint process: you can file a complaint at tdi.texas.gov if your insurer is acting in bad faith
When to Consider Hiring a Public Adjuster
For large or complex water damage claims in Houston, particularly those involving hurricane damage, significant mold, or disputes about coverage, a public adjuster can help you navigate the claims process and potentially increase your settlement. Public adjusters in Texas are licensed by TDI and work for you, not the insurance company. They typically charge 10 to 15% of the claim settlement. Whether that cost is worth it depends on the size of your claim and the complexity of the dispute.
- •Consider a public adjuster for claims over $25,000
- •Consider a public adjuster if the initial settlement offer seems significantly lower than repair estimates
- •Consider a public adjuster for complex multi-coverage claims (homeowners plus flood insurance)
- •Public adjusters in Texas are licensed by TDI; verify the license at tdi.texas.gov
- •Fee is typically 10 to 15% of the final settlement
- •Do not sign anything with a public adjuster during the first 24 hours after a loss
Frequently Asked Questions
No. The flooding caused by Harvey, where bayous overflowed and water entered homes from outside, is flood damage, not water damage. Standard homeowners insurance does not cover flood damage. Tens of thousands of Houston homeowners discovered this after Harvey because they did not have separate NFIP flood insurance. If your home is in a FEMA flood zone, flood insurance is typically required by your mortgage lender.
