Does Homeowners Insurance Cover Sewage Backup in Texas?
Short answer: often no, unless you added coverage for it. Most homeowners policies used in Texas exclude water that backs up through sewers or drains. Coverage usually comes from an optional add-on called a water backup endorsement, sometimes listed as "water backup and sump overflow." If you have it, cleanup and repairs are generally covered up to the endorsement limit.
Because policies differ between companies, the only reliable answer is in your own policy. The sections below explain what to look for and what to do right after a backup so a claim is not weakened.
How coverage usually breaks down
| What happened | Usually covered by |
|---|---|
| Sewage backs up through a toilet, tub, or floor drain | Water backup endorsement, if you have one |
| A water supply pipe inside the home bursts | Standard homeowners policy in most cases |
| Rain or creek water flows into the home | Flood insurance (NFIP or private) |
| A pipe leaked slowly for months | Often excluded as wear or maintenance |
| The city sewer main backed up into your home | Depends on your policy; the city may also accept a claim in some cases |
How to check your policy
Look at your declarations page first. Endorsements are usually listed there by name and form number, along with a dollar limit. Backup endorsements often have a separate, lower limit than your main dwelling coverage, such as $5,000, $10,000, or $25,000, so check the number and not just whether the line exists.
If you cannot tell, call your agent or insurer and ask directly: "Do I have water backup coverage, and what is the limit?" The Texas Department of Insurance also offers consumer help if you have trouble getting a clear answer.
What to do right after a backup
- Stop using water in the house so the backup does not get worse.
- Photograph and video everything before anything is moved or thrown out: the water, the drain it came from, and every damaged item.
- Report the claim to your insurer the same day if you can. Late reporting can cause problems.
- Keep receipts for cleanup, plumbing, hotel stays, and anything you buy because of the loss.
- Get the plumber’s invoice in writing. It usually states the cause, such as roots or a collapsed line, which matters for the claim.
- Ask any cleanup company for photos, moisture readings, and an itemized invoice.
What about the sewer line itself?
Even with a backup endorsement, repairing or replacing the broken sewer pipe is often not covered, because policies tend to exclude wear, tree roots, and deterioration. Some insurers and utilities sell separate service line coverage for this. It is worth asking about if your home has an older clay or cast iron line.
In Garland, sewer line repairs require a City permit, and rental properties must use a state-licensed master plumber registered with the City. See the City of Garland sewer repairs page for current rules.
Flood is a separate policy
If water came from outside, like a flooded street or creek, a homeowners policy normally will not cover it at all. That takes flood insurance through the National Flood Insurance Program or a private carrier. New NFIP policies usually have a 30-day waiting period, so it cannot be bought after the storm is already on the way.
