The general rule
Home insurance is built to cover sudden, unforeseen events — fires, storms, burst pipes. It is not built to cover things that happen slowly, and almost everything that kills stumps happens slowly. Standard policies exclude gradual soil movement, settlement and subsidence, timber rot, termite damage, and wear and tear. A timber stump that rotted through over fifteen years, or a house that settled as reactive clay dried out over several summers, falls squarely inside those exclusions.
Insurers treat stumps the way they treat roofs: a maintenance item that owners are expected to inspect and renew. That is frustrating when you are facing a $15,000–$30,000 bill, but it is consistent across the industry, and the same logic applies to underpinning on slab homes.
The exceptions worth knowing
The word doing all the work in your policy is sudden. Movement caused by a one-off insured event sits outside the maintenance exclusions:
- Escape of liquid — a burst or leaking pipe that washes out or saturates the soil under stumps. This is the most common successful path for subfloor claims.
- Storm and flood — water inundation that scours soil or shifts footings, where your policy includes the relevant cover.
- Impact — a vehicle, falling tree or similar striking the structure.
Even then, insurers typically cover the damage the event caused — not the renewal of stumps that were already at end of life. Expect any settlement to reflect that distinction.
How insurers assess stump claims
Everything turns on cause attribution. The insurer's assessor, and often their engineer, will look under the house and form a view on what the dominant cause was: a sudden event, or long-term rot, termites and soil movement. The condition of the stumps matters enormously here — a sound stump undermined by a burst pipe reads very differently from a rotted stump that finally gave way during a storm. Your maintenance history matters too: years of blocked gutters or known drainage faults hand the insurer an easy gradual-cause argument.
If a pipe bursts or floodwater gets under your house, photograph everything before cleanup, keep the plumber's report, and note dates. Cause evidence gathered in the first week is worth more than anything reconstructed months later.
Running a claim properly
If you think a sudden event is in play, lodge the claim before starting permanent repairs — insurers are entitled to inspect the damage as it stands. Make the property safe, keep receipts for any emergency work, and gather your own cause evidence rather than relying solely on the insurer's assessor. A plumber's report identifying a burst pipe, or an engineer's report ($600–$1,200) attributing movement to a specific event, gives your claim a spine. Be factual and specific about dates: “the floor dropped noticeably in the week after the pipe burst” is a claim; “the floors have been getting worse for years” is an exclusion.
If the claim is declined
A declined claim is not always the end. Ask for the decision and the assessor's report in writing, and use the insurer's internal dispute resolution process — they must have one. If that fails and you believe the decision is wrong, the Australian Financial Complaints Authority handles insurance disputes at no cost to you.
What a denial should never do is stall necessary work. Stumps do not wait for paperwork, and a house left on failed stumps accumulates secondary damage in plaster, roofing lines and services. If the claim fails, treat the job as the maintenance item it probably is: check the signs guide to gauge urgency, get the numbers from the costs guide, and get quotes. Many households find a partial restump covers the genuinely failed stumps at a fraction of the full-house price.

Common questions
Does insurance cover termite-damaged stumps?
Almost never. Termite and borer damage is a standard exclusion in Australian home policies, as is the rot that often accompanies it. Some policies sell limited pest-related extras, but renewal of termite-eaten stumps is treated as maintenance. Prevention and regular inspections are the realistic protection.
A burst pipe undermined my stumps — is that claimable?
Often, yes. Sudden escape of liquid is a standard insured event, and damage caused by the washout — including re-supporting affected footings — can be covered. Expect the insurer to separate event damage from pre-existing wear: they may fund repairs to affected stumps but not a whole-house restump.
Can I insure a house that already needs restumping?
Generally you can buy or hold cover, but pre-existing damage is excluded, and any future claim in the affected areas can be contested on maintenance grounds. Some insurers ask about known structural movement at application. Fixing the stumps removes both the risk and the argument.
Will lodging a stump claim raise my premium?
A single declined claim typically has little effect, though claim history questions at renewal vary by insurer. A paid structural claim can influence pricing. Weigh that against the amount at stake — on a genuine sudden-event claim worth five figures, premium effects are a secondary concern.
