What homeowners insurance covers, peril by peril
Twelve perils against the standard HO-3 form, the part that failed versus the damage it caused, and four questions to settle before a loss.

The short answer
A standard HO-3 homeowners policy covers sudden, accidental damage such as a burst pipe, fire, smoke, wind and hail. It excludes flood, sewer backup without an endorsement, gradual seepage, wear and tear, and mold outside a narrow exception.
Flood needs a separate NFIP or private policy. The Insurance Information Institute publishes the HO-3 wording; your declarations page decides your own answer.
What decides whether a loss is covered?
A burst supply line, a slow leak and rising floodwater can look identical on the floor and get three different answers.
The HO-3 sample pays for what the escaping water damaged and excludes the pipe or appliance it escaped from.
Endorsements, deductibles and settlement basis change the answer. Where it is unclear, ask your insurer in writing.

Which perils does a standard homeowners policy cover?
The middle column is what the HO-3 sample form and the Insurance Information Institute say about a standard policy. It is not a decision about your loss.
| Peril | In a standard HO-3 | What decides it |
|---|---|---|
| Sudden discharge from plumbing or an appliance | Covered. The III: the HO-3 “covers you for accidental discharge of water from a plumbing system.” | That it was sudden. The system or appliance itself is excluded; tear-out to reach it is included. |
| Gradual seepage and slow leaks | Excluded. The III: seepage “is viewed as a maintenance issue and is not covered by insurance.” | How long it ran, and whether it was or should have been noticed. Evidence of timing decides it. |
| Flood and rising water | Excluded. FEMA: “Most homeowners insurance does not cover flood damage.” | A separate NFIP or private flood policy, with a 30-day wait on a new NFIP policy. |
| Wind | Covered, the III says, as a named peril. | Evidence of the opening. A separate percentage deductible can apply to wind, hail or hurricane. |
| Hail | Covered, the III says, as a named peril. | Roof age and condition, and whether your roof settles at actual cash value. Ask. |
| Fire and lightning | Covered on every policy type the III lists. | Intentional loss is excluded in the HO-3 sample. If the home stands empty, ask about vacancy terms. |
| Smoke | Covered. The HO-3 sample names “sudden and accidental damage from smoke.” | Photos of deposits before cleaning. Ask how wildfire smoke and ash are handled. |
| Sewer and drain backup | Excluded from the base form; available as an endorsement or separate product. | Whether the endorsement is on your declarations page, and its limit. |
| Mold | Excluded, except hidden mold caused by an accidental discharge inside walls, ceilings or floors. | Whether the water event was covered, and any mold limit your policy sets. |
| Frozen pipes | Covered if you used reasonable care to keep heat on, or shut off and drained the water. | The heat condition, above all in a vacant or seasonal home. |
| Earthquake and earth movement | Excluded. The III: sold as additional coverage. | A separate policy or endorsement, where your state’s market offers one. |
| Wear, tear and neglect | Excluded. Insurance covers accidents, not aging. | Nothing. It is the line the seepage and roof arguments are drawn against. |
Run the same questions against your own loss with the is it covered tool, then the arithmetic with should I file a claim.
Does insurance pay for the pipe that burst?
No, in the HO-3 sample: it pays for what the water damaged. Tear-out to reach the failed part sits between the two, and the sample form includes it.
| The thing that failed | The damage it caused |
|---|---|
| The burst supply line, split hose or cracked pipe | Soaked drywall, insulation, flooring and the ceiling below |
| The water heater that let go | The flooded utility room and what was stored in it |
| The worn roof covering | Rain damage inside, but only where a covered peril such as wind made the opening |
| The appliance that failed | The cabinets and floor it discharged into |
Left column: excluded in the HO-3 sample. Right column: covered, subject to the peril rules above. Ask your adjuster in writing how access and tear-out is treated in your scope.
Where do covered water claims turn into disputes?
Seepage and wind-driven rain are disputes about a fact, how long a leak ran or what made the opening, so evidence decides them.
Photograph the failed fitting, the corrosion and the staining before anything is removed. Keep the part.
Write the date down now, while you remember it, and what you saw.
If a plumber or roofer attended, ask them to put the failure mode in writing.
NOAA and the National Weather Service publish storm records by place and date: the evidence a wind claim turns on.
How should flood and storm damage be documented when two policies respond?
One storm can trigger a homeowners claim for the roof and a flood claim for the ground floor: two adjusters, two deductibles, two files.
Mark which damage came from above (wind-driven rain) and which rose from outside (flood).
Photograph and measure it on walls and doors before cleanup.
One for each policy: estimates, invoices and letters never mixed.
File it with the insurer or agent that issued the flood policy. See flood damage restoration.
What should you check on your declarations page before a loss?
Four questions answer most of the table above for your own policy. Put anything you cannot find to your insurer in writing.
| Question | How the claim treats it |
|---|---|
| Is water or sewer backup on this policy? | Look for a line naming water backup, sewer backup or sump overflow, and its limit. The III says the coverage is available from most providers for a nominal cost. |
| Replacement cost or actual cash value? | For the structure and for contents separately. The HO-3 sample settles buildings at replacement cost and personal property at actual cash value. |
| What mold coverage is there? | Whether it is limited to the hidden-mold exception, and whether a separate mold limit applies. |
| Is there a separate wind, hail or hurricane deductible? | A percentage deductible is calculated on the policy limit, not the loss. The deductible calculator runs your number. |
Policy forms differ by insurer and by state, and change at renewal. Your state department of insurance regulates the insurers selling in your state.
Document the cause as carefully as the damage.
Nearly every row in the peril table is decided by where the water came from and when, not by how much of it there was. If the insurer takes a seepage or wear-and-tear position you think is wrong, there is a route through it.
What should you ask your insurer or adjuster?
And which exclusion, if any, are you considering?
Is removing and replacing material to reach the failed part in the scope?
And is there a separate mold limit?
The standard one, or a wind, hail or hurricane percentage?
An answer in an email outlasts one on a call.
What should you do with this page today?
The first pages of your policy: coverages, limits, deductibles and endorsements.
Write the answers somewhere you can find them.
The exclusions and conditions live in the form itself.
A new NFIP policy has a waiting period, so it is a decision for a quiet week.
Which mistakes cost coverage?
The hose, fitting or valve is the evidence that the failure was sudden. Keep it until the adjuster releases it.
EPA gives 24–48 hours to dry wet materials before mold can grow. A covered leak left wet can become mold the policy excludes.
It is not, in a standard form. Rising water needs a separate policy.
Cleaning removes the evidence behind the scope line. Photograph first.
A wrong date given early is hard to take back. Say what you know and when you noticed.
Whatever the coverage answer, a sewer backup is Category 3 work. See sewage cleanup.

Primary-source research and fact checking
We are a research desk, not a restoration company and not an insurance adjuster.
We read the federal agency guidance, the state insurance statute or the industry standard ourselves, and we publish the rule with the document it came from and the date we read it.
Where a number cannot be traced to a primary source, we publish the shorter page and say what we could not verify. The counts below are taken from the pages on this site.
- 56
- source documents linked from these pages
- 15
- government (.gov) domains among them
- 0
- average prices published without a source

- restoration jobs we perform
How this desk works
- Primary sources only. A mold rule comes from the EPA, a flood rule from FEMA and the NFIP, a claim rule from the state insurance statute. We do not cite an article that cites a source.
- Every figure carries its retrieval date. Guidance is revised and statutes are amended. A number without the date it was read cannot be checked.
- Paywalled standards are named, not quoted. IICRC S500 and S520 define the categories and classes of water and mold work. We describe their public structure and say plainly when the controlling text sits behind a purchase.
- Safety before the claim. Electricity near water, sewage, smoke and mold come first on every page where they apply. We explain the work; we do not tell you to do it yourself.
- We do not dry, remediate or rebuild anything, we do not adjust claims, and we take no payment for placement, ranking or a favorable mention.
Authorship on this site is organizational: the analysis belongs to the desk rather than to a named individual, and we do not publish credentials we do not hold. Our editorial policy sets out how we source, date and correct what we publish.
