People read the declarations page because it has numbers on it. Almost nobody reads the exclusions, which is where the policy explains what those numbers do not buy.
In an open peril policy the exclusions are the coverage definition. Everything is insured except what appears in that section, which makes it the most consequential part of the document.
How the section is built
Exclusions are not a flat list. They have a structure, and the structure is where claims are decided.
- The preamble. Language applying to everything that follows — commonly including the anti-concurrent causation clause, which extends an exclusion to a whole loss when an excluded cause contributes alongside a covered one.
- The excluded causes. The numbered list: earth movement, water damage, war, nuclear hazard, neglect, intentional loss, governmental action.
- The carve-backs. Sentences within or after an exclusion that put coverage back. This is the part almost nobody reads and the part that most often matters.
- The ensuing loss provision. Language covering damage that results from an excluded cause, even though the cause itself is not covered.
Never read an exclusion in isolation. Read from the preamble through to the end of that exclusion, including every sentence beginning "this exclusion does not apply to…" or "we do cover…". Reading only the sentence a denial letter quotes gives you half the picture, and frequently the wrong half.
The exclusions that produce the most disputes
Water damage
The broadest and most litigated. It typically excludes flood, surface water, water below the ground surface, and sewer or drain backup — while covering sudden discharge from a plumbing system inside the dwelling.
The same visible damage can therefore be covered or excluded depending entirely on where the water came from. Sewer backup is usually available as a separate endorsement, and it is one of the more commonly purchased add-ons for that reason.
Earth movement
Earthquake, landslide, mudflow, sinkhole, subsidence. Separate earthquake coverage exists as a policy or endorsement in most states, and a few states have specific sinkhole provisions.
Neglect and maintenance
Failure to use reasonable means to save and preserve property. Distinct from wear and tear, though it appears alongside it and is often invoked together.
Ordinance or law
The extra cost of rebuilding to current building codes rather than to the standard the property was originally built to. On an older property this gap can be substantial, and ordinance or law coverage exists as an endorsement precisely to close it.
Business and rental use
Property used for business, and liability arising from business activities. This one has grown in relevance as home working and short-term rentals have become common, and many households are exposed without realising it.
Intentional loss
Damage caused intentionally by an insured. Worth noting because policies differ on whether one insured's intentional act affects an innocent co-insured — a question several states address specifically.
Exclusions versus limitations versus conditions
Three different mechanisms that people conflate.
Exclusion This cause of loss is not covered at all.
Limitation or sublimit Covered, but only up to a smaller stated amount. Jewellery, cash and firearms typically have these.
Condition Something you must do — report promptly, mitigate, submit a proof of loss, cooperate. Coverage exists but can be defeated by failing to meet it.
Reading yours in twenty minutes
- Find the exclusions section — usually headed "Exclusions" or "Losses We Do Not Cover", separately for property and for liability.
- Read the preamble and note whether anti-concurrent causation language appears.
- Go through the numbered list and mark every exclusion that is realistic for your property and location.
- For each one marked, read to the end and highlight any carve-back.
- Find the ensuing loss provision and note what it restores.
- Check the endorsement list on your declarations page: some endorsements remove an exclusion, others add one.
What we are not saying
We are not saying exclusions are unfair. A policy that covered everything at any price would be a different product entirely, and exclusions are how coverage is priced to be affordable.
What we are saying is that the exclusions section is where your coverage is actually defined, that carve-backs and ensuing loss language sit inside it and are routinely overlooked, and that twenty minutes with this section tells you more about your position than any other part of the document.
Where to verify this yourself
- Your policy — the full exclusions sections, including preamble, carve-backs and ensuing loss provisions.
- Your declarations page — endorsements that add or remove exclusions.
- Your state Department of Insurance — state-specific rules on particular exclusions, which vary.
The structure, drawn
Six carve-backs worth knowing about
Wording varies by form and insurer, so treat these as patterns to look for rather than as text to expect verbatim.
| Exclusion | Typical carve-back pattern |
|---|---|
| Water damage | Sudden and accidental discharge from a plumbing system inside the dwelling is generally covered, unlike flood or seepage |
| Wear and tear | Ensuing loss covered — the worn component excluded, the damage it caused frequently not |
| Freezing of pipes | Covered where heat was maintained, or where the water supply was shut off and the system drained |
| Theft | Excluded from a dwelling under construction, but the exclusion typically ends once occupancy begins |
| Faulty workmanship | Ensuing loss frequently covered, even though the defective work itself is not |
| Power failure | Off-premises failure excluded, but damage from a resulting covered peril on the premises may be covered |
The freezing carve-back is worth flagging for anyone who leaves a property empty in winter. Whether heat was maintained, or the system properly drained, frequently determines the whole claim — and it is one of the few exclusions where an action you take beforehand directly controls the outcome.
Two exclusions that catch modern households
Business and rental use
Standard policies limit business property to a small stated amount and exclude liability arising from business activities. The definition of business is generally broad — any trade, profession or occupation, sometimes catching activities generating income above a modest threshold.
Home working, online selling, tutoring, freelancing, storing inventory, and short-term rental can all fall inside it. The exclusion turns on the activity rather than on whether you registered a company or consider it a business.
Vacancy and occupancy
Most policies restrict coverage on dwellings vacant or unoccupied beyond a stated period — commonly 30 or 60 days. After that, several perils are frequently excluded entirely, including vandalism, glass breakage, and water damage from freezing.
This catches people during a renovation, an extended absence, a property sitting between a move and a sale, and after an inheritance. A vacancy permit endorsement exists precisely for it, and it requires the insurer to know the property is empty.
Liability exclusions run separately
Property policies contain two distinct exclusions sections, and people frequently read only the first.
Commonly excluded from personal liability
- Business activities, including from a home
- Motor vehicles, which belong to the auto policy
- Watercraft and aircraft above stated sizes
- Intentional acts
- Injuries to household members
- Communicable disease transmission, in many forms
- Contractual liability assumed under an agreement
- Specified dog breeds, where an endorsement applies
- Professional services
The professional services exclusion is the one that surprises people who work in licensed fields. A homeowners policy does not respond to a claim that your professional work caused someone a financial loss, however that work was performed — that requires professional liability coverage, which is a separate product.
How to read the section in twenty minutes
-
Minutes 1–3
Read the preamble
Look for "concurrently or in any sequence", "directly or indirectly", "regardless of any other cause". If any appear, your policy contains anti-concurrent causation language and it applies to everything below.
-
Minutes 4–10
Mark the exclusions that are realistic for you
Earth movement matters in some places and not others. Water damage matters everywhere. Focus on what your property and location actually face.
-
Minutes 11–16
Read each marked exclusion to the end
Every sentence, including the exceptions. Highlight any carve-back and any ensuing loss language.
-
Minutes 17–19
Check the definitions section
Words in quotation marks or capitals are defined terms, and the policy definition frequently differs from ordinary usage.
-
Minute 20
Check the endorsement list
Endorsements add and remove exclusions. A form number on your declarations page can change what you just read.
Exclusions that can usually be bought back
Several standard exclusions have an endorsement available that restores coverage, at a price.
Commonly available
- Water backup and sump overflow
- Service line coverage
- Equipment breakdown
- Ordinance or law
- Home business, at limited levels
- Vacancy permit
Requires a separate policy
- Flood
- Earthquake, in most states
- Professional liability
- Commercial activity beyond incidental
- Vehicles
- Short-term rental, in many cases
We do not sell any of these and receive nothing if you buy them. The point of the table is that the left column is a conversation with your existing insurer, while the right column means a different policy entirely — and knowing which is which saves a wasted phone call.
What we are not saying
We are not saying exclusions are unfair. A policy covering everything at any price would be a different product, and exclusions are how coverage stays affordable and how risks get priced to the people who actually face them.
What we are saying is that in an open peril policy the exclusions section is the coverage definition, that carve-backs and ensuing loss language sit inside it and are routinely overlooked, and that twenty minutes with this section tells you more about your actual position than any other part of the document.
The definitions section does half the work
An exclusion is only as broad as the words inside it, and many of those words are defined elsewhere in the policy with meanings that differ from ordinary usage.
Policies signal defined terms by putting them in quotation marks or capitals. When an exclusion refers to a defined term, the exclusion means whatever the definitions section says — not what the word means in conversation.
Terms worth looking up in your own policy
- Flood — frequently narrower or broader than people assume, and central to water disputes
- Occurrence — determines how many deductibles apply
- Business — frequently broad enough to catch side activities
- Insured — who is actually covered, including household members and guests
- Residence premises — some coverage applies only there
- Vacant and unoccupied — these mean different things in most policies
- Earth movement — often wider than earthquake alone
The vacant and unoccupied distinction is a good example. In many forms a property with furniture in it but nobody living there is unoccupied, while one emptied of contents is vacant, and the two trigger different provisions. Reading the exclusion without the definition gives you half the answer.
One question for your insurer
Ask which exclusions on your policy can be bought back by endorsement, and what each would cost. Insurers rarely volunteer this list, and it is the fastest way to find out whether a gap that matters to you is closeable for a modest amount or requires a separate policy entirely.
This is general education, not advice. Insurance law and claim rules vary by state and change over time. Nothing here is legal, financial, or insurance advice for your situation, and reading it does not create any professional relationship. For your specific case, consult a licensed professional in your state or contact your state Department of Insurance.
