Does Homeowners Insurance Cover Basement Flooding?

Short answerIt depends on the water's source and your policy. A burst pipe in the basement may be covered. Floodwater, groundwater seeping through the walls and sewer or sump backups usually aren't covered by a standard policy. Those need flood insurance or an added endorsement, and federal flood insurance has limited basement coverage. Check your policy.

Where the water came from

This is the usual pattern, not a promise for your policy:

Burst pipe or sudden appliance leak: often covered, per the Texas Department of Insurance.
Flood or surface water: excluded in the sample HO-3 form (ISO's October 2000 edition). Needs flood insurance.
Groundwater seeping through walls or floors: excluded in the sample form. The Insurance Information Institute treats seepage as a maintenance issue.
Sewer, drain or sump backup: excluded in the sample form unless you add an endorsement.

Flood insurance has limited basement coverage

FEMA says flood insurance does cover basements, but coverage is limited. It defines a basement as any area with a floor below ground level on all sides. FloodSmart lists these basement items:

Covered under a standard policy if installed and connected to power: central air conditioners, furnaces, water heaters, sump pumps, electrical switches and light outlets.
Covered with contents coverage if connected to power: washers, dryers, window air conditioners, and freezers and their contents.
Not covered: finished basements and improvements, couches, televisions, photographs and keepsakes.

Timing matters

FEMA says there is a 30-day waiting period after you apply and pay, with some exceptions, so you can't count on buying flood coverage once water is on the way.

What to do now

As general safety advice, if the water may be touching electrical equipment, stay out and call your utility or an electrician. Take photos. EPA advises drying wet areas within 24 to 48 hours, and says sewage or contaminated water calls for professional cleanup.

Check your policy

Read your own policy, including any endorsements, and ask your agent or insurer how it applies to your situation. Your state insurance department can answer questions about coverage and take complaints. This page describes general patterns, not what your policy will pay.

Common questions

Is a sump pump failure covered?

Usually not without an endorsement. The sample form excludes water that overflows from a sump or sump pump, and Wisconsin's regulator says backup coverage is an endorsement you may need to ask for.

Does flood insurance cover my finished basement?

FEMA says finished walls, floors and ceilings and belongings in finished basements aren't covered. Cleanup costs and equipment such as furnaces and water heaters can be.
