In most cases, standard homeowners insurance does not cover sewer line repairs unless the damage is sudden, accidental, and caused by a covered peril such as fire, explosion, or vehicle impact, and the line is located on your property. Damage from wear and tear, poor maintenance, floods, pests, earthquakes, or tree roots is typically excluded unless you have purchased an additional endorsement for sewer line coverage. Understanding what is and is not covered can help you avoid costly surprises.

When Sewer Line Repairs Are Covered
Homeowners insurance is designed to protect against sudden, unexpected losses caused by specific perils listed in your policy. While sewer lines are usually excluded from standard coverage, you may be covered if:
- The sewer line damage happens suddenly and accidentally
- The cause is a covered peril in your policy
- The damaged section is located on your property
Example: If a vehicle accidentally drives onto your yard and crushes part of your underground sewer line, your homeowners insurance may cover the cost of repairs up to your policy limit.
Common Causes That Are Not Covered
Most sewer line problems result from gradual damage or issues that insurance companies consider preventable. Common uncovered causes include:
- Wear and tear from aging pipes
- Corrosion or natural deterioration over time
- Poor installation or construction defects
- Tree root intrusion into the pipes
- Flooding from heavy rain or storms
- Damage from pests such as rodents or insects
- Earthquake-related damage
Example: If your clay sewer pipe cracks after decades of use, your insurer will likely deny the claim because the cause is considered normal deterioration.
Adding a Sewer Line Endorsement
Many insurers offer an optional service line endorsement or sewer line rider that can be added to your homeowners policy for an extra premium. This add-on can cover repairs or replacements for buried utility lines, including sewer lines, damaged by certain causes that standard policies exclude.
Coverage and limits vary, so review the details with your insurance agent. This small investment can help prevent thousands of dollars in out-of-pocket costs.
What About Septic Tanks?
If you have a septic system, your homeowners insurance might cover sudden and accidental damage to the tank or connecting pipes caused by a covered peril. However, issues from neglect, lack of maintenance, or wear and tear are generally not covered.
Example: If a lightning strike damages your septic pump, your policy might pay for repairs. But if the pump fails due to rust and lack of service, you’ll have to cover the expense yourself.
Tree Roots and Sewer Line Damage
Tree roots are a frequent cause of sewer line blockages and cracks. Unfortunately, damage from roots is typically excluded from coverage. In rare cases, if root damage is deemed sudden and accidental (such as a nearby tree falling and breaking the pipe), your insurer may consider it.
Even if the pipe repair is excluded, some policies may cover secondary damage—for example, water backup that damages your flooring. However, this usually requires separate water backup coverage.
Tips to Prevent Sewer Line Problems
Prevention can save you from major repair bills and insurance disputes. Consider these tips:
- Schedule professional sewer line inspections every few years
- Replace outdated clay or metal pipes with modern PVC
- Install root barriers if you have trees near your sewer line
- Avoid flushing wipes, grease, and non-biodegradable items
- Maintain your septic system according to manufacturer guidelines
When to Contact Your Insurance Provider
If your sewer line is damaged, contact your insurance company as soon as possible. Provide details about the cause, location, and extent of the damage. Your adjuster will determine whether your policy covers the loss.
If you’re unsure, an insurance agent can help you review your policy and recommend additional coverage if needed.
