You might assume that your homeowner's insurance has you covered no matter what, but that's rarely true. Every year, thousands of homeowners are shocked when their claims are denied for reasons buried deep in the fine print. Whether it's storm damage that's technically "flooding," or an aging roof labeled "wear and tear," these denied claims can leave families footing massive repair bills on their own.

The good news? Most denials are preventable with a few smart homeowner moves and the right coverage in place. Here's what to watch for, and how to avoid becoming the next claim denial story.

Flood, earthquake, & landslide damage without specialty coverage

Standard homeowners' policies usually exclude damage from flooding, earthquake, land movement, or sinkholes. Claims submitted for flood-related damage will likely be denied if you lack flood insurance.

Instead, investigate adding flood insurance, earthquake riders, or land movement endorsements (sometimes through separate policies). If you live in a zone prone to these risks, carry proof of that supplemental coverage.

"Wear and tear" & maintenance-related damage

Insurers routinely deny claims that result from normal aging, gradual decay, or neglect. For instance, a roof that's aged and wasn't maintained is a common denial. Maintain your home diligently. Keep records (receipts, photos) of upkeep like roof inspections, gutter cleaning, plumbing checks. Document the pre-damage condition so an insurer can't blame long-term deterioration.

Water, mold, & moisture damage from gradual leaks

Many claims for water damage are denied because insurers view them as the result of ongoing leaks, not sudden accidents. Mold damage is often denied if it stems from persistent leakage or poor maintenance.

Immediately stop leaks, mitigate further damage, and document the source. Act as if you are doing damage control first; then file a claim. Prompt reporting gives you a better footing.

Dog bites & liability for excluded breeds

Most standard homeowners or personal liability policies cover dog-bite claims, except for certain breeds or dogs with prior bite history that insurers explicitly exclude. Disclose your dog when getting your policy. If your dog is a commonly excluded breed, seek a policy that allows it (or a separate liability rider). Keep animal behavior records or training evidence to reduce risk.

Using your home for business without commercial coverage

Running a business out of your home (e.g. daycare, workshop, Airbnb) typically exceeds the scope of a homeowner's policy. If a claim relates to business activity, you could get denied outright. Make sure to disclose any home-business operations to your insurer. Add a business-use endorsement or carry a separate commercial policy for business assets and liability.

Damage to a vacant or unoccupied home

If your home sits empty (for weeks or months), insurers often consider it a higher risk and exclude claims arising during vacancy. Many policies have clauses that void coverage after a certain vacancy period.

Before leaving and when vacant, check your policy's vacancy clause. Maintain security, HVAC, and plumbing, and monitor regularly. Consider vacancy insurance or an "unoccupied home" addendum.

Missed deadlines, insufficient documentation, & policy lapses

Even for valid claims, insurers may deny because you delayed filing, failed to document damage properly, or let your premium lapse.

Try to file your claim as soon as possible, and document everything (with photos, receipts, etc). Always keep your policy active by paying premiums on time. Ask for a written explanation if denied; that gives you a fighting chance to appeal.

Pre-existing damage & misrepresentation

Insurers may deny a claim by arguing that the damage already existed before your policy started or that you misrepresented the state of your home.

To avoid this problem, be honest when applying for coverage. If you've made improvements, document them. Take "before" photos regularly, so when a loss occurs, you can show the change that occurred after the policy was active.

High-value items over policy limits

Standard policies set sublimits for jewelry, furs, fine art, and collectibles. If a ring or watch is stolen and you didn't schedule it (or buy a floater), the claim can be paid only up to a low limit or denied for the excess.

Update your inventory list regularly and purchase scheduled coverage to avoid this. Keep receipts and appraisals so you have proof of value.

Sewer backup & water-backup exclusions

Damage from sewer or sump-pump backups is often excluded from standard policies. Homeowners who assume "water damage" covers everything are surprised when sewage or groundwater claims are denied.

You may need to add a water-backup endorsement or purchase separate coverage to cover these potential problems.

Pest & insect damage

Damage from pests, like termites, carpenter ants, and rodents, is almost always excluded because it's considered preventable or due to neglect. Insurers will close these claims as maintenance items, not covered losses.

Typically, the best approach is to schedule routine pest inspections and remediate problems promptly to avoid extensive damage.

Ordinance, building code, & undocumented renovations

If rebuilding after a loss requires bringing systems up to current code, that extra cost can be excluded unless you have ordinance or code coverage. Also, unpermitted renovations might lead to denied claims.

Prepare to keep permits and contractor receipts for any upgrades done to your home, as these can act as "proof" that your home was up to code.

Bottom line

Many homeowners only discover coverage gaps after a claim is denied, when it's too late to fix them. Knowing what your home insurance won't cover is one of the smartest homeowner moves you can make. Regular maintenance, honest disclosure, and the right add-on policies can save you from thousands in unexpected repair bills.

A home warranty and a homeowner's policy aren't the same thing. A warranty covers appliance and system breakdowns, while insurance protects against larger, sudden losses, meaning you may need both to truly protect your home budget.
