In 2026, standard Texas policies exclude sewer backups, leaving you unprotected against drain overflows or sump pump failures. To gain coverage, you must add a Water Backup endorsement. At Neill Insurance Brokers, we highly recommend this affordable add-on, as it covers cleanup and interior repairs, closing a critical gap that standard “sudden and accidental” pipe burst coverage simply doesn’t reach.
Why Sewer Line Damage Is Usually Not Covered
Imagine this scenario.
Your drains start backing up. A plumber inspects the issue and finds that the sewer line from your home to the street has collapsed. Repairing it requires digging up your yard.
The cost comes in around $7,500.
You call your insurance company, expecting help, and they tell you it is not covered.
This situation is far more common than most homeowners realize.
Our agency founder, Scott Neill, spent a decade as a captive Farmers agent before establishing Neill Insurance Brokers as an independent firm. Today, with our team managing 304 active homeowner policies and over $6 million in premium across North Texas, we routinely audit policies that completely miss this gap. We’ve seen families forced to pay $15,000 out-of-pocket for raw sewage cleanup simply because their previous agent never explained these exclusions.
Standard Texas homeowners policies, specifically HO-3 policies, exclude damage to underground pipes and service lines. This is not hidden language. It is a clearly defined exclusion that applies to most policies.
The Two Problems Homeowners Confuse
Many homeowners think sewer issues are all the same. They are not.
There are two completely different types of claims, and both are typically excluded.
Sewer and Drain Backup
This occurs when water from a municipal sewer system flows back into your home through drains, toilets, or sinks.
- Can cause $10,000 to $30,000 in interior damage
- Affects flooring, walls, and personal belongings
Service Line Damage
This involves the physical failure of the underground pipe connecting your home to the street.
- Requires excavation and pipe replacement
- Often costs $3,000 to $10,000 or more
These are separate risks, and each requires its own coverage endorsement.
Why North Texas Homes Face Higher Risk
If you live in North Texas, your risk is even higher.
The primary reason is the soil.
North Texas has heavy clay soil that expands when wet and contracts when dry. This constant movement places stress on underground pipes over time.
Add in older neighborhoods in areas like Arlington, Roanoke, Fort Worth, and Denton, where many homes still have original cast iron or clay sewer lines, and the risk increases significantly.
For many homeowners in North Texas, sewer line failure is not a matter of if, but when.
The Two Coverages That Protect You
The good news is that these risks are preventable with the right endorsements.
Sewer and Drain Backup Coverage
This coverage protects your home from damage caused by sewer backups.
- Typically costs $40 to $100 per year
- Covers cleanup, repairs, and damaged contents
- Claims often range from $15,000 to $25,000
Service Line Coverage
This coverage applies to the underground pipes outside your home.
- Typically costs $30 to $60 per year
- Covers excavation, pipe replacement, and yard restoration
- Claims usually range from $3,000 to $10,000
For roughly $70 to $160 per year, you can cover two of the most common and expensive homeowner risks in North Texas.
How to Check If You Have This Coverage
You can verify your coverage in just a few minutes.
Open your homeowners insurance policy and review the endorsements section. Look for:
- Water backup and sump overflow
- Sewer and drain backup
- Service line coverage
- Underground service line
If you do not see these listed, you likely do not have coverage.
If your annual premium is under $2,000, there is a strong chance these protections were excluded to keep the price lower.
Frequently Asked Questions
Does a standard Texas homeowners insurance policy cover sewer line damage?
No. Standard Texas homeowners policies (including common HO-3 forms) explicitly exclude water backup from sewers or drains, as well as the physical failure of underground service lines. To get protection, you must manually add specific endorsements to your policy.
What is the exact difference between Water Backup and Service Line coverage?
Water Backup coverage pays for the interior damage and cleanup costs if dirty water backs up through your toilets, sinks, or sump pump. Service Line coverage pays for the exterior excavation, pipe replacement, and yard repairs if the underground utility lines (sewer, water, electric) leak or collapse between your house and the street.
How much does it cost to add sewer backup and service line coverage in Texas?
Bundling both endorsements is highly affordable. Water Backup coverage typically costs between $40 and $100 per year, while Service Line coverage ranges from $30 to $60 per year. Combined, you can secure full underground and backup protection for roughly $70 to $160 annually.
Why are North Texas homes at a higher risk for underground pipe failure?
North Texas features heavy clay soil that expands dramatically when wet and shrinks when dry. This constant shifting shifts your home’s foundation and puts severe mechanical stress on buried pipes. The risk is compounded in older neighborhoods throughout Arlington, Fort Worth, and Denton, where aging cast iron or clay pipes are highly prone to cracking.
Avoid a Costly Surprise
Sewer line damage and backups are two of the most common and expensive issues Texas homeowners face, yet they are almost always excluded from standard policies.
The real risk is not the cost of coverage, it is the cost of going without it.
