A homeowners policy covers more than most people realize, but what it leaves out is where high-value households get caught. According to a recent Insurance Information Institute survey, nearly 60% of homeowners couldn't name a single exclusion in their own policy. And the gap between what people assume is covered and what actually is can run into tens of thousands of dollars. The exclusions are an important part of the exposure that a high value home carries: catastrophe perils, high-value contents, code-driven rebuild costs, and liability that is higher than a standard limit.
The good news is that many of these gaps can be closed. Nearly every common exclusion has a specialty line or endorsement built to close it. Knowing which exclusion maps to which fix is where Bulwark can help.
Key takeaways
- Two of the perils most capable of destroying a home, flood and earthquake, are never covered by a standard policy.
- Several "slow" losses are excluded by design: wear and tear, mold, pests, and gradual water damage.
- High-value items aren't excluded, but they're capped at low sublimits until you schedule them.
- Almost every gap is can be closed with flood, earthquake, water-backup, valuable-articles, ordinance-or-law, and excess-liability coverage.
The big two
Catastrophe perils are excluded outright
Flood
No standard homeowners policy covers flood, which includes rising water, storm surge, or overflow from outside the home. It's the single most important exclusion to understand. Coverage comes from a separate flood policy: the federal NFIP, which caps at $250,000 on the dwelling. Or, for a high-value home, a private or excess flood policy that insures the full rebuild cost above that cap.
Earthquake and earth movement
Quakes, landslides, mudflow, and sinkholes are excluded across the board. Coverage is added by an earthquake endorsement or a standalone policy. In quake- or flood-exposed regions, a difference-in-conditions (DIC) policy can bundle both perils together at limits a standard policy can't reach.
Where you live changes the policy
In high-risk regions, the headline perils get carved out too
Flood and earthquake are excluded everywhere, but in catastrophe-prone areas the perils a policy normally covers can be limited as well. In coastal and hurricane regions, wind and named-storm damage is often moved to a separate windstorm or hurricane deductible, or excluded entirely, leaving a state wind pool or standalone windstorm policy to cover it. In wildfire-exposed areas, carriers increasingly cap, surcharge, or decline fire coverage, pushing homes onto a state FAIR plan. The lesson: in a high-risk location, read how wind and fire are handled as carefully as the flood and quake exclusions.
Water you'd assume is covered
Not all water damage is treated the same
A standard policy covers sudden, accidental water from inside the home — a burst pipe, an overflowing appliance. It does not cover:
- Sewer, drain, and sump-pump backup — excluded by default, and a common, expensive loss. Filled with a water-backup endorsement.
- Surface water and flooding from outside — that's flood, covered only by a separate flood policy.
- Gradual leaks and seepage — treated as maintenance, not a sudden loss (see below).
Wear, neglect, and the slow losses
Insurance covers the sudden, not the inevitable
Wear and tear and deferred maintenance
Excluded. A policy pays for accidents, not for the predictable decline of a roof or a deck.
Mold
Usually excluded or sharply sublimited, unless it results directly from a covered sudden event. An endorsement can raise the limit.
Pests and vermin
Termites, rodents, and insects are excluded as preventable.
Mechanical and equipment breakdown
Failure of HVAC, water heaters, and home systems isn't a covered peril; an equipment-breakdown endorsement adds it.
Service lines
Damage to the buried water, sewer, or electrical lines you own can fall outside the policy; service-line coverage closes that gap.
Off-premises power failure
An outage starting at the utility, and the resulting spoilage or surge damage, generally isn't covered.
Fine print at rebuild
OLD DWELLINGS AND A NEW CODE
Ordinance or law
When you rebuild after a loss, current building codes apply, and bringing an older or custom home up to code can add substantial cost. Standard policies include only a small ordinance-or-law allowance, often a fraction of the dwelling limit. Raising it is inexpensive and matters most for older, historic, and architecturally distinctive homes.
A few exclusions can't be covered, and shouldn't surprise you: war, nuclear hazard, government seizure, and intentional acts are always excluded across the market.
Value and liability gaps
WHERE A STANDARD POLICY CAPS YOU
High-value contents
Jewelry, watches, art, wine, furs, and collectibles aren't excluded, but they're capped at low sublimits (often a few thousand dollars for theft). A scheduled personal-property / valuable-articles floater insures each item at an agreed value, against a broader range of losses, usually with no deductible.
Liability above your limit
Your home's personal-liability limit is finite, and a serious claim can exceed it. An umbrella or excess-liability policy extends it into the millions and coordinates with your auto coverage.
Home-based business
Business property and liability run from the home are excluded under a personal policy; they need a business endorsement or a separate commercial policy.
Short-term rental and home-sharing
Renting the home out isn't covered under a standard personal policy; a home-sharing endorsement or specialty landlord policy is required.
Higher-risk liability
Certain dog breeds, trampolines, and pools (as "attractive nuisances") are often excluded or surcharged on personal liability; an umbrella carrier may still cover them, but confirm rather than assume.
How the gaps get closed
The specialty lines that sit alongside your policy
Most of what a standard policy excludes is covered by a purpose-built line or endorsement:
| Exclusion | How it's covered |
|---|---|
| Flood | NFIP or private/excess flood |
| Earthquake | Endorsement, standalone, or DIC policy |
| Wind & wildfire | Windstorm/hurricane endorsements, a state wind or FAIR plan, or a DIC policy in high-risk zones |
| Water backup | Sewer, drain, and sump-pump endorsement |
| Valuable articles | Scheduled coverage for jewelry, art, wine, and collections |
| Ordinance or law | Increased limit for code-driven rebuild costs |
| Equipment breakdown & service line | For home systems and buried utility lines |
| Excess liability | An umbrella above your home and auto limits |
A well-structured insurance program layers the right coverages over the base policy, so the exclusions that matter for your home are covered and you're not paying for the ones that don't.
Common questions
Does homeowners insurance cover water damage?+
Some of it. Sudden, accidental water from inside the home — a burst pipe or a failed appliance — is covered. Flooding from outside the home is not (that needs flood insurance), and sewer or sump-pump backup is excluded unless you add a water-backup endorsement. The cause of the water, not the water itself, decides whether it's covered.
Why isn't flood covered by my homeowners policy?+
Flood was carved out of standard policies long ago because the risk is too concentrated and catastrophic for an ordinary policy to absorb — which is why federal and private flood programs exist instead. It's a true exclusion everywhere, not a sublimit, so a separate flood policy is the only way to cover it. For a high-value home, a private or excess flood policy covers rebuild costs above the NFIP's $250,000 cap.
Are my jewelry and art fully covered?+
Not under the base policy. Standard homeowners coverage caps categories like jewelry, watches, and art at low sublimits, often only for certain causes of loss. Scheduling each item adds agreed-value coverage against a broader range of losses — including accidental damage and mysterious disappearance — usually with no deductible.
What is ordinance or law coverage, and do I need it?+
It pays the extra cost of rebuilding to current building codes after a covered loss. A standard policy includes only a small allowance, which can fall well short on an older or custom home where code upgrades are expensive. Raising the limit is inexpensive and worth it for anyone whose home predates current codes or has non-standard construction.
Can I cover earthquakes if I'm in a quake zone?+
Yes. Earthquake is excluded from every standard policy but available by endorsement or as a standalone policy, and a difference-in-conditions policy can combine quake and flood coverage at higher limits. In exposed regions it's often the peril most capable of totaling a home, which makes it worth pricing rather than assuming it's covered.
Know your gaps before they find you.
Every exclusion above is knowable, and nearly every one is fillable. The work is matching your home's real exposures — its location, age, contents, and how you use it — to the specific lines that close them.
