Homeowners insurance does not cover flood damage, but it does cover certain types of water damage, depending on the cause. If your basement floods, in order to be covered the water damage will have had to happen suddenly and accidentally, like from a burst pipe.
Does homeowners insurance cover a flooded basement?
Standard homeowners insurance doesn’t automatically include any form of flood insurance coverage. [1] Below are instances when homeowners insurance will cover water damage to a basement — and when it won’t.
When does homeowners insurance cover a flooded basement?
Homeowners insurance may cover water damage to your basement if it's deemed “sudden and internal,” meaning it was unpreventable and the source of damage came from inside your home, like a burst pipe.
Here are a few causes of a flooded basement that would likely be covered under a standard homeowners insurance policy.
Plumbing
Homeowners insurance covers water damage caused by the accidental leakage of plumbing. That means if a pipe bursts in the middle of the night and damages everything in your basement, your homeowners insurance may help pay for repairs.
However, homeowners insurance does not cover maintenance issues or general wear and tear. So if your pipe bursts because it’s old or you didn’t properly maintain it, you wouldn’t be covered.
Accidental overflow of water from a tub or sink
If your tub overflows or your sink is accidentally left on and the water floods your basement, your homeowners insurance may cover you.
Appliance leakage
If an appliance that is connected to plumbing in your home, like an air conditioning system or a water heater, suddenly leaks and damages your basement, your homeowners insurance may cover you. Again, if the piping or appliance breaks due to negligence or maintenance issues, you wouldn’t be covered.
Damage caused by a separate peril
If your basement floods due to a separate covered peril like fire or windstorms, your homeowners insurance may help pay for repairs.
For example, if your house catches fire and firefighters have to extinguish the fire using water hoses, your homeowners insurance can cover both the fire and water damage that was incurred.
Or if a hail or windstorm shatters a few windows in your basement and rainwater gets in, your homeowners insurance may pay for repairs that the hailstorm caused.
Malicious activity
Homeowners insurance covers damage that’s caused by malicious activity, like vandalism, break-ins, or rioting. If someone breaks into your home and leaves the water running which results in your basement flooding, your homeowners insurance may still cover you.
When doesn't homeowners insurance cover a flooded basement?
Homeowners insurance does not cover flooding, which means if a hurricane, named storm, or tidal wave floods your basement, your homeowners insurance wouldn’t pay for the damage. In order for flood damage to be covered, you’d need a separate flood insurance policy (more on that later).
Here are a few common instances when homeowners insurance won’t cover water damage.
Floods or rising rainwater
Homeowners insurance excludes coverage for some natural disasters, including floods. If a flood leads to water filling your basement and your personal property is damaged, you wouldn’t be able to file a claim with your homeowners insurance company.
Seepage of groundwater
After a heavy rainfall, groundwater can seep through to your home’s foundation. This type of water damage isn’t covered by homeowners insurance and may not be covered by flood insurance unless it was directly caused by a flood.
Sewage backup
If sewage or water backs up into your basement, your homeowners insurance won’t cover the damage unless you have additional coverage, like a water backup endorsement.
Sump pump flooding
If you have a sump pump in your basement to protect it from flooding and that sump pump fails, your homeowners insurance likely excludes coverage for the sump pump itself along with the water damage it causes — unless you have an endorsement on your policy that extends coverage to sump pump failure.
Maintenance issues
Homeowners insurance doesn’t cover maintenance issues or damage that occurs over time.
For example, if an old pipe had been leaking and you never got around to repairing it and it eventually bursts, you’d be on the hook for the cost of repairs to your flooded basement. Pests are also considered maintenance issues, so if a pipe bursts in your basement because of a rat or mouse infestation, the damage likely won’t be covered.
Flood insurance coverage for basements
You can purchase separate flood policies or add endorsements to your homeowners policy to make sure you’re protected against certain flood risks.
Flood insurance
If you live in an area that’s at high risk of flooding, consider purchasing a standalone flood insurance policy. Flood insurance is available through both the government-backed National Flood Insurance Program (NFIP) and private flood insurance companies. [2]
However, flood insurance through the NFIP doesn’t offer coverage for items in your basement or any underground area of your home. This means anything that’s stored or located in your basement — like your furniture, appliances, flooring, and TVs — wouldn’t be protected under your NFIP policy.
That’s where private flood insurance comes in. A few private insurers including Neptune, Allstate, and Chubb offer flood insurance policies with optional coverage for items stored in your basement.
Water backup coverage
Water backup coverage is a popular endorsement that protects you from water damage due to a sewage, sump pump, or drainage backup. It’s also a relatively inexpensive endorsement, costing around $30 per year, which makes it a smart addition for most homeowners. It’s important to note that this type of coverage won’t pay to fix or replace your sump pump, just the water damage it may cause.
How to file a claim if your basement is flooded
Here are the steps to take to file an insurance claim if your basement is flooded:
Survey the damage. Investigate what caused the flood and how much damage there is in your basement.
Document the damage. Take pictures of your flooded basement, including any damage to your home and belongings, as well as potential causes of the flood, like broken windows or pipes. You’ll also want to gather any receipts or other documents that your insurance company might need to process your claim.
Take steps to protect your property. Mitigate any further damage as quickly as possible, including draining the water and bringing in fans, dehumidifiers, and other equipment to remove any water that has soaked into the floor and walls.
Contact your insurance company. Once you have documentation of the flood and have taken steps to prevent further damage, reach out to your insurance company to file a claim. A claims adjuster will be sent to your house to review the damage and process your claim.
