What Events Are Not Covered by Homeowners Insurance?
Floods, earthquakes, and normal wear and tear top the list. Neglect and pest damage are usually excluded too.
Free to compare
Flood and Water from Outside
A standard policy covers a burst pipe inside the house. It does not cover water that comes in from outside, like a river overflowing or rain pooling against the foundation. That needs a separate flood policy, and lenders near water often require it.
Earthquake and Earth Movement
Shifting, sinking, or shaking ground is excluded on a standard policy. This includes earthquake damage. If the area has any seismic activity, ask whether a separate earthquake policy is worth adding before closing, since this type of damage otherwise won't be paid.
Maintenance Falls on You
Roof leaks from age, rotting wood, rusted pipes, or anything that broke down slowly counts as wear and tear, not a covered loss. Insurers expect the homeowner to keep the house maintained. A pre-purchase inspection report is worth keeping, since it shows the home's condition at closing.
Pest and Vermin Damage
Termites, rodents, and other pests cause damage insurers treat as preventable, not sudden or accidental, so it's left off the covered list. For an older house, a pest inspection before closing can catch problems early. Damage found after you own it will be your cost to fix.
Check the Policy Before You Sign Anything
The same dwelling coverage amount can come with different exclusions, deductibles, and prices across insurers. Comparing before closing means finding the gaps now, not after a loss finds them for you.
What About Sewer Backups, Mold, or a Tree Falling on the House?
A sewer or drain backing up into the house is usually its own exclusion, separate from the flood and water issues already covered. Standard policies often leave it off unless it's added back as an endorsement, sometimes called water backup coverage. It's inexpensive on most policies and worth asking about directly, since it won't show up unless you look for it on the declarations page or ask the insurer by name.
Mold is a mixed case. If a pipe bursts and is fixed quickly but mold grows anyway, many policies cover the mold cleanup as part of that covered loss. If mold grows slowly from a leak nobody noticed, or from humidity in a bathroom without a fan, that's treated as a maintenance issue and excluded. The difference comes down to whether the water damage itself was covered. Some insurers cap mold cleanup at a lower dollar amount than other repairs, so the limit is worth checking even when the coverage exists.
A tree falling on the house is usually covered, even if the tree was dead or diseased before it fell, because the damage itself is sudden. What is not covered is removing a tree that falls in the yard without hitting anything insured, like a shed or the house itself. Some policies pay a small amount toward debris removal regardless, but it's limited. Ordinary yard maintenance, trimming a tree before it becomes a hazard, is on the homeowner, not the insurer.
Power surges and electrical damage from a lightning strike are typically covered, but a surge from a utility company issue or old wiring that finally fails is treated differently depending on the cause. War, nuclear hazard, and government seizure of property are standard exclusions on every policy, though they rarely come up for an ordinary buyer. None of these are things to memorize before closing. They're things to ask about specifically, since the answer depends on the exact policy language, not on what's typical.
What About Jewelry, Business Property, or a Dog Bite?
A standard policy covers personal belongings, but it caps certain categories at a low dollar amount no matter what the overall contents limit says. Jewelry, watches, furs, and similar items are usually capped somewhere between one and two thousand dollars total, even if a single ring is worth far more. The same goes for cash, firearms, and collectibles. If any of these apply, a scheduled personal property endorsement covers the specific item at its appraised value, but it has to be added by name. It won't happen automatically just because the item is in the house.
Running a business from home changes the picture too. A standard policy covers some business equipment at a small limit, often a few thousand dollars, which covers little more than a laptop and a printer. It does not cover business liability, meaning if a client visits the house and gets hurt, or if business inventory is damaged, that claim is likely denied. Anyone working from home with inventory, equipment, or regular client visits should ask about a separate endorsement or a business policy before assuming the homeowners policy has it handled.
Dog bites and other liability claims depend on the dog, not just the policy. Most insurers cover dog bite liability as part of standard personal liability coverage, but many exclude specific breeds by name, or exclude any dog with a prior bite history. Some insurers decline to write a policy at all if certain breeds are in the house, which matters for closing if the dog is already part of the household. This is worth asking about directly and by breed, since the list varies by insurer and isn't printed in plain language on most policies.
None of these gaps are unusual or a sign of a bad policy. They are standard limits that exist on nearly every homeowners policy sold, and they are manageable once known. The point before closing is not to memorize every exclusion but to list what's actually in the house, the jewelry, the home business, the dog, and ask how each one is handled under the specific policy being bound. A declarations page answers some of it. A direct question answers the rest.
Before You Sign the Binder
Pull the declarations page and check the exclusions list line by line against what's actually in the house. If something's missing, like water backup or a scheduled item, ask about adding it before closing, not after.
