What Does Homeowners Insurance Not Cover for Water Damage?
Last updated October 26, 2026
The short answer
Common Exclusions
Most standard policies exclude gradual damage that happens over time, such as a slow pipe leak behind a wall that goes unnoticed for months. If the leak is sudden and accidental, like a burst pipe, coverage may apply, but the distinction matters. Keep records of when you first noticed the issue.
Water from outside the home, like heavy rain flooding your basement through a foundation crack, is usually not covered unless you have separate flood insurance. Similarly, sewer or drain backups are often excluded unless you add a specific endorsement. Check your policy declarations to see what is listed as a covered peril.
- Gradual leaks and seepage
- Flooding from outside sources
- Sewer or drain backup
- Neglect or lack of maintenance
- Earth movement that causes water damage
What About Mold and Mildew
Mold damage is frequently excluded or limited in standard policies. If mold results from a covered water loss, some policies may pay for a small amount of remediation, but often you need a separate mold rider. Discuss the limits with your insurance agent before you file a claim.
If you discover mold after a water event, document the extent with photos and notes. A mold professional can assess health risks and recommend safe removal. Do not disturb large areas of mold without protection, and see a doctor if you feel unwell from exposure.
What Is Typically Covered
Sudden and accidental water damage from internal sources, like a burst washing machine hose, an overflowing bathtub, or a leaky water heater, is often covered. The resulting damage to floors, walls, and personal belongings may be included, but the cost to repair the appliance itself is usually not.
Coverage also depends on the cause. If a tree falls through your roof during a storm and rain enters, that is usually covered under wind or falling object perils. However, if the storm causes a river to overflow and flood your home, that is flood damage, which requires separate coverage.
Steps to Protect Yourself
Review your policy annually and ask your insurance company about specific exclusions, such as flood and sewer backup. Consider adding separate policies if you live in a flood-prone area, even if not required. Document your home's condition with photos and a written inventory of your belongings.
If water damage occurs, take steps to dry the area within 24 to 48 hours to reduce mold growth. Use fans and dehumidifiers if safe. Contact a water damage professional for an inspection and documentation of the loss before you start cleanup. Keep all receipts and records for your claim.
