The address and any details you enter in the quote tool go to Neptune Flood and are handled under Neptune's own privacy policy, not Prevent's. Any quote, price, or policy shown comes from Neptune and its insurers, not from Prevent Insurance Agency. Prevent is an independent agency and may be paid a commission if you buy a policy through this tool. Coverage is bound only when confirmed in writing by the insurer.

Four things to know before you buy

Flood is the one major cause of loss that your property policy almost certainly leaves out. These are the facts that decide whether a flood policy is right for you — each with its source.

Your homeowners policy does not cover flood

Floods are not covered under standard homeowners and renters policies. Flood insurance is a separate policy, and building and contents coverage are usually sold separately.

The flood zone is not the whole story

A lender requires flood insurance in a high-risk zone, but water does not read maps. Check your official FEMA zone, then check the forward-looking Flood Factor for the same address before you decide.

There is a waiting period — do not buy during the storm

A National Flood Insurance Program (NFIP) policy has a 30-day waiting period before it takes effect. Private flood policies set their own; the quote tool shows the effective date before you buy.

NFIP limits may be lower than your home is worth

NFIP residential coverage is capped at $250,000 for the building and $100,000 for contents, with contents paid at actual cash value. Private and excess flood policies can go above those limits.

Prevent the loss, not just insure it

The best flood claim is the one you never file. A sump pump with battery backup, a water sensor at the lowest point of the building, utilities raised off the basement floor, and clear gutters and drains cut both the chance and the size of a loss. We keep a vetted list of the devices that do this well.
