You've been paying for homeowners insurance for years. You have a policy, a declarations page, coverage limits that seem reasonable. And then something happens. A sewer backs up. A slow leak finally shows itself. Your claim gets denied. That's often when people discover that their policy doesn't cover what they assumed it would.
Every homeowners policy has exclusions. These aren't loopholes or fine print designed to trick you — they're standard limitations that apply to most policies. Understanding what's typically not covered helps you know where you might need additional protection, or at least what to expect if something goes wrong.
Common exclusions in most policies
While every policy is different, here are the types of damage that standard homeowners insurance typically doesn't cover:
Flood damage
Water that comes from outside your home — whether from heavy rain, an overflowing river, or storm surge — is considered flood damage. This is one of the most common surprises, because it feels like water damage should be water damage. But standard homeowners policies draw a clear line: water from inside (like a burst pipe) is usually covered; water from outside isn't. You'd need separate flood insurance for that. You can learn more about flood insurance in our dedicated guide.
Earthquake damage
If you live in an area with seismic activity, earthquake damage typically requires a separate policy or endorsement. This includes not just the quake itself, but also damage from aftershocks or related ground movement.
Sewer backup and sump pump failure
If your sewer line backs up into your home, or your sump pump fails and causes water damage, that's usually not covered under a standard policy. Some insurers offer this as an optional endorsement, often called "water backup coverage." To better understand water damage coverage, see our water damage guide.
Damage from lack of maintenance or gradual wear
If your roof has been slowly deteriorating and finally fails, or if a pipe has been leaking behind a wall for months, insurance typically won't cover it. Policies are designed to cover sudden, unexpected events — not ongoing maintenance issues or gradual deterioration.
Mold (in most cases)
Mold coverage is complicated. If mold grows as a direct result of a covered event (like a burst pipe), it might be covered. But if it develops from ongoing moisture problems, high humidity, or a slow leak, it's usually not. And even when it is covered, there are often strict limits on how much the policy will pay.
Certain types of personal property
Your policy covers your belongings, but often with limits on specific categories. Jewelry, art, collectibles, and expensive electronics might be covered up to a certain amount — sometimes as low as $1,000 or $2,000 total. If you have valuable items, you may need additional coverage through a scheduled personal property endorsement or floater. These are common signs you might be underinsured.
Damage from pests, insects, or animals
Termite damage, rodent infestations, bat colonies in your attic — these are considered maintenance issues, not sudden accidents. Even if a raccoon causes damage getting into your home, coverage can be limited.
War, nuclear hazard, and intentional loss
These are extreme exclusions that apply to most policies. Damage from war, nuclear events, or anything you deliberately caused won't be covered.

Why these exclusions exist
Insurance is designed to cover sudden, unexpected, accidental events — a tree falling on your roof during a storm, a kitchen fire, a pipe that bursts in freezing weather. As the National Association of Insurance Commissioners (NAIC) explains, standard policy exclusions typically fall into a few categories:
- Predictable or preventable (maintenance issues, wear and tear)
- Catastrophic and widespread (floods, earthquakes — events that would affect entire regions at once and require separate risk pools)
- Controllable by the homeowner (pest control, regular upkeep)
This doesn't mean the exclusions are fair or convenient — just that they follow a certain logic about what insurance is meant to protect against.
Where to find exclusions in your policy
Your declarations page won't list every exclusion, but it will show any endorsements or riders you've added (like earthquake coverage or scheduled personal property). These additions tell you where you've extended coverage beyond the standard policy.
The detailed exclusions live in the main policy document, usually in a section called "Exclusions" under Section I (property coverage). That's where you'll see the specific language about what's not covered. It's also helpful to learn about your deductible so you understand what you'll pay out of pocket when you do file a claim.
Some policies also have "special limits of liability" — these are sub-limits on certain categories, like $1,500 for jewelry or $2,500 for business property kept at home. You'll find those listed either in the declarations page or in the policy's coverage section.
The main takeaway
Exclusions aren't there to surprise you — they're standard across most homeowners policies. The important thing is knowing what's not covered so you can decide if you need additional protection (like flood insurance or a rider for valuables) or at least understand what you'd be responsible for if something happens.
