Hurricane Season: Flood Damage and What Warranties Exclude

If you live along the Gulf or Atlantic coast, hurricane season brings a familiar to-do list. One item that often gets overlooked is understanding what your car and home warranties will and won't pay for after a storm. The short answer: flood and storm damage are almost always excluded, which is why the right insurance matters so much.

Why warranties exclude storm damage

Home warranties and vehicle service contracts are designed to cover breakdowns from normal use and wear, or from mechanical and electrical failure. They are not insurance against outside events.

Most contracts specifically exclude damage caused by:

• Floods, storm surge and rising water.
• Wind, hail and fallen trees.
• Lightning and power surges, in many plans.
• Fire, earthquakes and other natural disasters.
• Mold, mildew and water intrusion from outside the home.

So if floodwater ruins your HVAC condenser or your car's electronics, a warranty claim will typically be denied. That's not a loophole. It's a basic part of how these contracts are written.

Where insurance fits in

Insurance is designed for sudden, external losses. Here's how coverage usually divides up, though you should confirm with your agent:

• Homeowners insurance often covers wind damage, but standard policies generally exclude flooding. Some coastal areas have separate windstorm policies or higher hurricane deductibles.
• Flood insurance is usually a separate policy, available through the National Flood Insurance Program or private insurers. New policies often have a waiting period before they take effect, so don't wait until a storm is forecast.
• Auto insurance with comprehensive coverage generally covers flood damage to vehicles. Liability-only policies typically do not.

Review your policies before the season starts, not after a storm is named.

Preparing your home

A few steps can reduce damage and speed up recovery:

1. Document everything. Take photos or video of your home, systems and appliances, inside and out.
2. Raise what you can. If flooding is possible, consider elevating items in basements or garages.
3. Secure outdoor equipment. Your AC condenser should be properly anchored. Bring in or tie down loose items.
4. Test your sump pump and consider a battery backup.
5. Know how to shut off utilities, including power, gas and water.
6. Keep important documents in a waterproof container or saved digitally.

Preparing your vehicle

• Fill the gas tank or charge your EV ahead of the storm.
• Park on high ground or in a sturdy garage, away from trees.
• Keep your insurance and service contract documents in a safe place.
• Never drive through flooded roads. Even shallow water can stall a car or sweep it away.

After the storm

If your car was in floodwater, don't try to start it. Water in the engine can cause serious damage if you crank it. Call your insurance company and have the car towed for inspection.

For your home, have a licensed electrician or HVAC technician inspect equipment that was underwater before you turn it back on.

Be cautious buying used cars after a major storm. Flood-damaged vehicles sometimes reach the market. Check the vehicle history report, look for damp carpets, silt or rust in unusual places and have a mechanic inspect it.

Report insurance claims quickly and keep receipts for any emergency repairs, like tarping a roof or pumping water out. Take photos before you clean up, and don't throw away damaged items until your adjuster says it's okay.

Will your warranty still help later?

Yes, for normal breakdowns. A storm doesn't cancel your contract. If your water heater fails months later from ordinary wear, that claim can still be covered under the usual terms. The exclusion applies to damage caused by the storm itself. Our home warranty overview explains typical coverage and exclusions in more detail.
