Does Homeowners Insurance Cover Water Damage?
General information on what policies commonly cover and exclude. Your policy is what counts.
This is general information about how homeowners policies commonly work in the United States. It is not legal or insurance advice. Coverage depends on your actual policy, its endorsements, and your state’s laws. Read your policy and talk to your insurer or agent.
The basic rule: sudden and accidental
Most standard homeowners policies (often an HO-3 form) cover water damage that is sudden and accidental and comes from inside the home's systems, such as a burst pipe, a water heater that splits, or a washing machine hose that fails. They usually do not cover damage that happened gradually over time, like a slow leak under a sink or a shower that leaked into the subfloor for months.
Commonly covered vs. commonly excluded
| Often covered (subject to your policy) | Often excluded or limited |
|---|---|
| Sudden burst pipes | Flood and surface water |
| Appliance and water heater failures | Gradual or repeated leaks |
| Accidental overflow of a tub or sink | Sewer and drain backup (without endorsement) |
| Roof leaks caused by a covered storm | Groundwater seepage |
| Tear-out to reach a broken pipe | Wear and tear, lack of maintenance |
| Additional living expenses if the home is unlivable from a covered loss | Mold (often limited by a sublimit) |
Flood is separate
Damage from rising water, overflowing rivers, storm surge, and heavy rain flowing over the ground is a flood. Standard homeowners policies exclude it. Flood coverage comes from the National Flood Insurance Program (NFIP), managed by FEMA, or from private flood insurers. New NFIP policies generally have a 30-day waiting period before they take effect, with some exceptions, so buying after a storm is forecast usually doesn't help. NFIP coverage has limits and limited coverage in basements.
Sewer backup endorsement
Water that backs up through drains or a sump pump that fails is usually excluded unless you add a water backup endorsement. It's often inexpensive compared with a basement cleanup, but check the limit.
Mold
Many policies exclude mold or cap it at a sublimit. Mold that results from a covered sudden loss may be covered up to that limit. Mold from humidity or long-term leaks usually isn't.
Condos and renters
In a condo, the association's master policy usually covers the building and common elements, while your HO-6 policy covers your interior improvements, belongings, and liability. Renters need a renters (HO-4) policy for belongings; the landlord's policy covers the building, not the tenant's things.
Your duties after a loss
Policies typically require prompt notice and reasonable steps to prevent further damage (mitigation). That's why insurers expect you to stop the water and start drying. Keep receipts for emergency work. Learn more in how water damage claims usually work.

What is a water backup endorsement?
An add-on to a homeowners policy that covers damage from water backing up through sewers or drains, or sump pump overflow, usually up to a set limit.
Does insurance cover a slow leak?
Usually not. Damage that occurred gradually over time is commonly excluded.
