What Isn't Covered Under Home Insurance?
Floods, earthquakes, and routine wear and tear are the big ones. Check your declarations page for other exclusions specific to your policy.

Checking whether your damage falls outside your policy
If the adjuster's offer or denial pointed to an exclusion, start by reading what they cited, not what you assumed was covered. Water damage is the most disputed one. A pipe that burst is usually covered, but water that seeped in over time, or rose up from outside as flooding, is not. Earth movement, including earthquakes and often sinkholes, is excluded unless you bought a separate policy for it. So is damage from neglect, like a roof that leaked for months before anyone fixed it. If the denial doesn't match what you saw happen, ask the adjuster which exclusion applies and how they decided the cause. The cause of the damage, not just the damage itself, is usually what decides whether it's covered.
If part of the damage is excluded and part isn't, the payout should still cover the portion your policy includes, and that split is worth checking against what the adjuster offered. An exclusion on one claim doesn't mean your coverage is wrong for the next one. If this policy left a gap you didn't expect, comparing what other insurers would have covered costs nothing and might close it before the next loss.
What else homeowners policies usually leave out
Beyond floods, earthquakes, and wear and tear, a standard policy leaves out several things people assume are covered until a claim shows otherwise. Mold is one of them. If mold grows because a pipe burst and you reported it right away, the resulting damage is often covered as part of that claim. If it grew because moisture sat for weeks, most policies treat it as a maintenance issue and deny it outright. The distinction comes down to timing and whether the mold was a foreseeable result of neglect, which is why adjusters ask so many questions about when you first noticed water or a smell.
Pest damage falls outside coverage almost without exception. Termites, rodents, and insects are treated as a maintenance problem, not a sudden loss, even when the damage is extensive and you had no way of seeing it coming. The same logic applies to a foundation that cracks from settling, or pipes that corrode and fail from age rather than a single event. Insurance is built around sudden and accidental damage. Anything that happens gradually, no matter how costly, tends to fall on the other side of that line.
Certain high-value items also have limits built into the policy regardless of what caused the damage. Jewelry, fine art, firearms, and collectibles are usually capped at a low dollar amount, often a few thousand dollars total, unless you added a rider or scheduled the item specifically. If an adjuster's offer for a stolen ring or a damaged collection seems low, check your declarations page for a jewelry or valuables sublimit before assuming the cause of loss was the problem. The exclusion may have nothing to do with what happened and everything to do with what category the item falls into.
Business property kept at home, and damage from running a business out of the house, sits outside a standard homeowners policy too. A home office with a laptop and a desk is normally fine, but inventory, business equipment, or a client injured on the property while conducting business can fall into a gap that neither the homeowners policy nor a lack of other coverage was built to fill. If part of the loss involves anything business-related, that portion is worth asking about separately, since it may need its own policy rather than a rider on this one.
What to do when the damage falls into more than one category
Most denials don't come from a single clean exclusion. A storm tears off part of the roof, water gets in, and mold starts before anyone notices. The wind damage is covered. The water that followed might be too, if it came from the storm. The mold might not be, if it sat long enough to count as a maintenance failure. One event can cross three categories in the same claim, and the adjuster is supposed to sort out which part belongs where, not deny the whole thing because one piece of it doesn't qualify.
Checking that sorting yourself is worth doing before accepting an offer. Ask for the claim to be broken down by cause, not handled as one lump sum. If the adjuster attributes all the damage to the excluded cause when part of it clearly traces back to the covered event, that's a reasonable thing to push back on, and it's a common reason initial offers come in low. Photos and a timeline of when you noticed each sign of damage matter here, since the whole dispute often comes down to what happened first and how fast it was reported.
Additional living expenses, the cost of staying somewhere else while the house is repaired, follow the same split logic. If the house is uninhabitable because of a covered loss, that coverage applies even if an excluded issue also contributed to the damage, as long as the covered cause is what made the home unlivable. Check your declarations page for the limit on this coverage, since it's usually capped as a percentage of your dwelling coverage or a set dollar amount, and it runs out faster than people expect if repairs drag on.
If the claim stays stuck after that, most states require insurers to give a written reason for a denial or a reduced payout. That letter has to cite a specific policy provision, not just a general explanation, so request it in writing if it hasn't been given. From there, an independent adjuster or a public adjuster can review the same damage and the same policy language. Either they confirm the insurer's read or they give something concrete to dispute. A claim that was denied outright and a claim that was paid at the wrong amount call for the same first step. Get the reasoning in writing, then compare it line by line against what the policy actually says, not against what seems fair.
