Does homeowners insurance cover water damage?

It depends. Most basic home insurance policies have limited coverage for water damage. As a homeowner, it's important to understand exactly what you're covered for in case of water damage.

Generally speaking, water damage may be covered under your home insurance policy if the damage is “sudden and accidental.” For example, damage from a frozen pipe bursting or a roof leak from a fallen tree may be covered if you've kept your home in a good state of repair.

Water damage caused from on-going leaks or lack of maintenance is generally not covered by home insurance. This includes things like leaks from aging roofs, gradual damage from leaky faucets, and mold or rot from lack of addressing moisture issues.

Basic home insurance also generally doesn't cover water damage caused by sewer backup and sump pumps — unless you add an optional coverage, known as Water Backup coverage (or “Water Backup and Overflow” coverage in some states).

What is Water Backup coverage?

Water Backup, also referred to as “sewer and sump pump overflow,” or “escape of water” coverage, is an optional coverage homeowners can add to their policies to help cover the cost of water damage caused by sewer backups, or sump pump failures.1,2

What does Water Backup cover?

Water Backup may help cover water damage caused by:

  • Sewer backups
  • Sump pumps and other systems designed to remove water from the foundation of your home — even if the damage is due to a mechanical breakdown

To give an example, let's say the sump pump in your basement malfunctions and causes damage to the carpet. Water Backup will help cover the cost of replacing the carpet but not the sump pump or other equipment that contributed to the damage.

What doesn't Water Backup cover?

Water Backup does not cover:

  • Repairs from normal wear and tear of pipes, plumbing, and sump pump equipment
  • Water damage caused from water outside the home, such as from pools or bodies of water like the ocean
  • Flood damage
  • Damage from surface or sub-surface water

Does Water Backup cover floods?

No. Our Water Backup coverage does not cover damage from floods. Homeowners will need to purchase a separate flood insurance policy for coverage.
