Is underpinning covered by insurance Australia

Here’s a clear, plain-English summary of how most home policies treat foundation work.

The short answer and why most policies exclude it

The short answer: routine underpinning usually falls outside standard cover. Insurers often view permanent foundation work as preventative. That means the fix aims to stop future movement rather than repair sudden loss.

Most home insurance policies only respond after a sudden, insured event. Flood, storm or earthquake that causes movement may trigger a claim. Long-term ground shift and gradual subsidence are commonly excluded.

Preventative vs repair: how insurers classify work

Insurers class routine work as preventative, not an immediate repair.
Notify your insurer early if you spot structural damage or new cracks.
Provide dated photos and an engineering assessment to support any claim.
We prepare clear scopes and quotes to help you discuss options with your insurer.
If movement followed a covered event, claim avenues may exist.

For clear next steps, see our underpinning advice and call us for a fast, compliant assessment.

What insurers assess: cause, extent of damage, and policy wording

Insurers focus on cause, timing and the visible extent of harm when they assess a claim. They need clear evidence that movement was sudden rather than gradual.

Subsidence drivers in Sydney soils

Sydney clay shows large shrink–swell with wet and dry cycles. Trees draw moisture and can shift soil near footings.

Plumbing leaks, poor drainage and local site conditions also change moisture paths. These factors shape where and how much movement occurs.

Policy exclusions that commonly apply to foundations and walls

Most policies exclude long-term subsidence, settlement and normal wear. Assessors check the extent of cracks to walls and footings.

We document property evidence, map root zones and moisture pathways, and supply an engineering diagnosis. This factual base helps you decide whether a claim has merit.

Cause is central: clay, drought‑soak cycles and large trees drive movement.
Insurers test whether the event was sudden or gradual.
We clarify exclusions before you pursue a weak claim.

When can underpinning-related costs be covered

When severe weather or seismic events cause sudden movement, your policy may respond. We set realistic expectations about claim prospects and help you decide the best path.

Insured events and edge cases

Cover is most likely when a defined event directly causes movement and cracking. Examples include flood undermining footings or earthquake-induced settlement.

Edge cases need clear causation. Slow ground shift or long-term settlement is unlikely to meet policy wording. You should expect close scrutiny.

Documenting foundation damage for a claim

Strong evidence helps. We coordinate qualified engineers to prepare reports, level surveys and dated photos.

Cover is most likely when an insured event clearly caused the movement.
We supply a claim-ready pack: photos, levels, scope and costs.
We align foundation repair scopes with policy definitions where possible.
If cover is declined, we still propose safe, staged repairs and fixed-price quotes.

We guide you through home insurance conversations. You stay in control with clear options for your property and transparent next steps.

Underpinning costs today: realistic ranges and what drives them

We present realistic price bands so you can plan repairs with confidence.

Typical totals for a standard home usually run between $3,000 and $15,000+. The final cost depends on method, site access and soil.

Method-by-method guide

Mass concrete: $1,000–$3,000 per metre of footing.
Beam & base: $1,500–$3,500 per metre where conditions require it.
Mini-piles: typically $10,000–$20,000 per pile for deep support.
Resin injection: faster, less excavation, lower labour and time on site.

What shifts price

Soil type, location and site access change machinery and crew time.

House size and the extent of subsidence or damage increase scope and material needs.

Method	Typical range	Main drivers
Mass concrete	$1,000–$3,000/m	Excavation, concrete volume, access
Beam & base	$1,500–$3,500/m	Engineering design, labour, site constraints
Mini-piles	$10,000–$20,000/pile	Depth, piling rig access, load needs
Resin injection	Lower overall project cost	Soil type, speed, minimal excavation

We provide fixed-price quotes after inspection so you can plan with confidence. Call 1300 970 930 to book a site inspection and a clear, written quote.

Choosing the right solution: concrete underpinning, resin injection and screw piling

Choosing the right repair starts with matching the method to soil and load conditions. We assess the site, then recommend the safest, least disruptive solution that meets council rules.

Speed, disruption and compliance: why resin can be the least invasive

Resin injection uses expanding polyurethane to fill voids and re-level the ground. It is quick, clean and often finished in one day. You can usually remain at home while we complete the work.

When screw piles or concrete underpinning are the safer engineering call

Mass concrete and screw piles suit sites needing deeper bearing or higher loads. These types give permanent load transfer where soil strength is low.

Resin: minimal excavation, fast, low mess.
Concrete underpinning: deep, robust support for heavy loads.
Screw piles: precise depth control, good where access allows.
We choose the type that matches soil, loading and council compliance.

Method	Speed	Disruption	Best use
Resin injection	One day	Low	Void filling, re‑levelling light to moderate movement
Concrete underpinning	Days to weeks	High	Heavy loads, extensive structural repair
Screw piles	One to several days	Medium	Deep support with limited vibration

We prioritise safety, permanence and minimal disruption. The right choice solves the underlying problems, not just cosmetic repairs.

Certification, compliance and minimal disruption you can trust

Certification and council approvals matter as much as the physical work itself. We take care of permits, engineering sign-off and council-ready paperwork so your project flows without delays.

All work comes from licensed professionals and insured teams. We supply clear method statements and risk controls before starting. That keeps your home safe and reduces downtime.

Council-compliant methods, licensed teams and honest assessments

We give honest advice with no upsell. Our quotes match the engineering scope and the local approval process.

Resin projects often finish within a single day with minimal mess. Traditional concrete or piling methods use staged excavation and take more time on site.

FAQ

Is underpinning covered by home insurance in Australia?

Most home policies exclude work for pre‑existing foundation faults or gradual ground movement. Insurers usually cover sudden, accidental events that damage foundations—such as a severe storm or earthquake—only if your policy specifically lists those events. Read your policy wording and get an engineer’s report to support any claim.

Why do insurers often refuse claims for foundation repairs?

Insurers distinguish between gradual deterioration and sudden damage. Ongoing soil shrinkage, tree root migration or poor original construction are seen as maintenance issues. Policies commonly exclude wear, maintenance and latent defects, so cover is denied when the cause is not an insured per‑il.

What evidence do insurers require to consider a foundation claim?

Provide an engineering assessment, dated photos showing progression, plumbing and drainage reports, and any council records. A structural engineer’s clear cause statement is critical. Without it, insurers will often decline on the basis of insufficient proof of an insured event.

Can underpinning ever be covered after a flood or earthquake?

Yes. If an insured event such as a flood or an earthquake directly causes foundation failure, repairs including underpinning may be claimable. Check your policy’s natural disaster clauses, excesses and limits. Prompt documentation and lodgement improve the chance of a successful claim.

How much does underpinning typically cost today?

Costs vary widely. Minor localised repairs can start around ,000. Whole‑house underpinning often ranges from ,000 to ,000 or more depending on house size, access and soil. We recommend an on‑site engineer assessment to provide a reliable fixed quote.

What repair methods affect price and disruption?

Mass concrete pads, beam‑and‑base underpinning, mini‑piles or screw piles and resin injection each have different footprints. Resin is often least invasive and quick. Concrete methods are more disruptive but suit heavy loads. Access constraints and the extent of movement push costs up.

Which soil and site conditions in Sydney cause subsidence?

Sydney’s clay soils, steep blocks, shallow water tables and large street trees commonly drive movement. Seasonal moisture changes and poor drainage worsen the problem. An engineer will assess soil type, tree proximity and site levels to identify the root cause.

How long does an underpinning project usually take?

Small local works can finish in a few days. Whole‑house underpinning usually takes one to three weeks, depending on method and weather. Resin jobs often complete fastest. We plan work to minimise disruption and meet council approvals where required.

Do I need council approval and certification after underpinning?

Yes, many underpinning solutions require council approval and inspection. Final certification from an engineer or building surveyor confirms structural integrity. We coordinate approvals and provide compliance documentation for insurance or sale purposes.

How do insurers view preventative underpinning or strengthening?

Preventative upgrades are generally not claimable. Insurers consider these maintenance or improvement works, not repair to an insured loss. If you’re concerned about future movement, discuss risk mitigation with an engineer and your insurer before work begins.

What should I do first if I suspect foundation movement?

Arrange an urgent structural assessment. Take dated photos of cracks and sticking doors, check downpipes and gutters, and avoid DIY repairs. A prompt engineer’s report helps identify urgency, supports council applications and strengthens any potential insurance claim.

Will tree removal help my foundation problem and claims process?

Removing a problematic tree can stop further root‑induced shrinkage but may change soil moisture and cause short‑term movement. Document tree condition and removal timing. Discuss the plan with your engineer and insurer; coordinated action shows you’re managing risk responsibly.

Can we get a fixed‑price quote and insurance‑ready report from Underpinning Sydney?

Yes. We offer no‑obligation site inspections, fixed‑price quotes and engineering report coordination suitable for insurance lodgement. Call 1300 970 930 to book an inspection or email photos for an initial assessment.
