Does homeowners insurance cover flooding?

How long until a new flood policy starts?

How to get flood insurance

Ask the agent who handles your home or car insurance, or find one through FloodSmart.gov, FEMA's official flood insurance site. Private flood insurers also sell policies in many areas and are worth comparing.
