Wagga Foundation Repairs explains home building compensation cover (HBCF) as a statutory insurance scheme that protects NSW homeowners if their licensed builder dies, disappears or becomes insolvent before finishing contracted residential work, or fails to rectify defects; it is currently required for most residential building work above a set contract value, around $20,000 at the time of writing, though thresholds and exemptions can change. It comes up constantly in foundation repair quotes for underpinning and restumping, because both trades routinely quote jobs that sit near or above that threshold.
This page sets out what HBCF actually is, when it applies to structural foundation work in the Riverina, and why the certificate matters well beyond the day the work finishes.
What is home building compensation cover (HBCF), in plain terms?
HBCF (sometimes still called home warranty insurance, or referred to by its older acronym HIH-era “home owners warranty”) is a statutory last-resort insurance scheme created under the Home Building Act 1989 (NSW). It exists for one specific scenario: your licensed builder or contractor cannot finish the job or fix a defect because they’ve died, disappeared, or become insolvent, and the standard remedy (going back to the builder to make it right) is no longer available to you.
It is not general insurance against poor workmanship where the builder is still trading and able to be held to their warranty. It’s a safety net for the specific, if uncommon, case where the person contractually responsible for the work is no longer there to answer for it.
When does HBCF apply to foundation repair work in Wagga Wagga?
NSW’s home building compensation cover is currently required for most residential building work above a set contract value, around $20,000 at the time of writing, though thresholds and exemptions can change, so your contractor will confirm what applies to your specific contract before work starts. In practice, that means the answer depends heavily on the size and type of foundation job:
- A small partial restump or a single dropped corner might sit comfortably under the threshold.
- A full restump, a half-perimeter underpinning job, or anything approaching whole-of-house structural work will typically sit well above it.
- Jobs that hover right around $20,000 are the ones worth asking about directly, since a slightly different scope, method or set of extras can push a contract either side of the line.
The table below uses indicative figures already published in our underpinning cost guide and on the restumping and reblocking service page, lined up against where they typically sit relative to the threshold. These are budgeting ranges only, not quotes, and every job is confirmed after a proper inspection.
| Job type | Indicative cost range | Typically above the ~$20,000 HBCF threshold? |
|---|---|---|
| Partial restump (5-15 stumps) | $3,000-$10,000 | Usually below |
| Single dropped corner underpinning (2-4 underpins) | $8,000-$20,000 | Borderline; confirm with your contractor |
| Full restump, average 3-bedroom home | $15,000-$35,000 | Often above, depending on final scope |
| Half-perimeter underpinning (8-14 underpins) | $30,000-$60,000 | Above |
| Full perimeter underpinning (14+ underpins) | $50,000-$80,000+ | Above |
Two important caveats sit behind that table. First, thresholds and exemptions are set by regulation and can change, so treat “$20,000 at the time of writing” as exactly that: a figure current when this guide was written, not a permanent number. Second, whether your particular contract needs HBCF cover depends on the final contract price, not the ballpark range you started with, so ask your contractor to confirm it in writing as part of the formal quote.
How is HBCF different from home and contents insurance?
They protect against completely different risks, and confusing them is one of the more expensive mistakes a homeowner can make. Home and contents insurance is a policy you hold, covering damage to your property from events like storms, fire or (sometimes, subject to exclusions) sudden accidental damage. HBCF is cover the contractor arranges, protecting you specifically against contractor failure: death, disappearance or insolvency, or a refusal to rectify defective work where a tribunal has found in your favour.
Because this distinction trips people up so often, especially when foundation movement is involved, we’ve kept the fuller comparison on its own page rather than repeating it here: see our guide to foundation repair insurance in NSW for how home insurance, HBCF and contractor liability insurance actually differ, and which one (if any) is likely to respond to a given problem.
What does an HBCF certificate actually cover, and for how long?
An HBCF certificate is tied to a specific contract and a specific licensed contractor, and it generally responds to two broad categories of loss: the contractor failing to complete the contracted work (because they’ve died, disappeared or become insolvent), or the contractor failing to rectify work found to be defective, where that failure has been established (typically through a tribunal or court process) and the contractor still cannot or will not fix it. Statutory warranty periods for residential building work in NSW commonly distinguish between major defects and other defects, with major structural defects generally attracting a longer warranty period; your contractor’s paperwork will set out what applies to your specific contract.
This is exactly why underpinning and restumping quotes above the threshold should always come with HBCF details attached, alongside the contractor’s own licence information (full licence details are supplied with every quote arranged through us). If a contract value clearly requires it and the paperwork isn’t offered, that’s a fair, direct question to put to the contractor before signing anything.
Does restumping or underpinning always trigger HBCF?
Not always, and that’s exactly why the job type and job size matter more than the trade label. A small partial restump of a handful of stumps can sit under the threshold, while a full restump with bearer and joist replacement commonly runs $25,000 to $45,000 or more, well above it. Underpinning follows the same logic in reverse direction: a single dropped corner needing two to four underpins might land in the $8,000-$20,000 range (right on the borderline), while anything from a full elevation upward is squarely above it.
The honest answer, in both trades, is “it depends on the final contract price, confirmed by your contractor.” Nobody, including this page, can tell you in advance whether your specific job needs HBCF cover without knowing the actual contract value, and that number only exists once a site inspection and formal quote have happened.
Why does the HBCF paperwork matter if you sell the house later?
Because a future buyer’s conveyancer, building inspector or lender will likely ask for it, and having it ready turns a potential question mark into a solved problem. Our guide to selling a house with foundation issues covers this in more depth, but the short version is straightforward: documented, engineer-designed structural work with the HBCF certificate, the contract, licence details and warranty terms all kept together reads to a buyer as a fixed, accountable repair. The same work with no paperwork reads as a question nobody can answer, which tends to cost the seller more at the negotiating table than the original repair did.
Practically, that means treating the HBCF certificate the same way you’d treat the engineer’s report or the completion warranty: as something to file away permanently, not something to lose track of once the trades have left site.
What should you check for on your HBCF certificate?
At minimum, a genuine certificate should show the contractor’s name and licence number, the property address, the contract value, and the insurer or scheme reference for the cover. If any of those details don’t match your actual contract, or the contractor can’t produce a certificate at all for work that’s clearly above the threshold, that’s worth resolving before work starts, not after. Your contractor should be able to walk you through exactly what’s shown on your certificate and what it means for your specific job.
If you’re partway through weighing up a foundation repair and haven’t had a site inspection yet, that’s genuinely the right first step; ballpark figures like the ones on this page are useful for budgeting, but they can’t tell you your actual contract value, and therefore can’t tell you whether HBCF applies to your job. You can get a free quote and we’ll arrange an inspection with a licensed local specialist, with HBCF requirements confirmed as part of the formal quote.
Home Building Compensation Cover FAQs
Do I need HBCF cover for a small crack repair job?
Usually not. HBCF generally applies to residential building work above a set contract value, currently around $20,000, and straightforward cosmetic crack repair typically sits well under that figure. Structural work like underpinning or a full restump is far more likely to approach or exceed the threshold, which is why it’s worth confirming with your contractor whenever a quote starts climbing toward that range.
Who arranges HBCF cover: me or the contractor?
The licensed contractor arranges HBCF cover as part of undertaking contracted residential building work above the threshold; it isn’t something you separately purchase or apply for yourself. Your role is to check that the certificate has been provided and that its details (contractor, licence number, property address, contract value) actually match your job.
Is HBCF the same thing as builder’s warranty?
Not quite. Statutory warranties are the builder’s own ongoing obligation to remedy defects in their work for a set period. HBCF is the insurance fallback that exists specifically for when the builder can no longer honour that warranty, because they’ve died, disappeared or become insolvent, or won’t comply with a tribunal finding against them. You generally want both: a builder who honours their warranty, backed by HBCF cover in case they can’t.
What happens if my job is just under the $20,000 threshold?
Then HBCF cover may not be required for that specific contract, though thresholds and exemptions can change, so it’s worth confirming rather than assuming. It’s also worth knowing that quotes can shift once an inspection uncovers extra scope (rotted bearers found during restumping, for example), which can move a contract from just under the threshold to just over it.
Will my home insurance pay out instead of HBCF?
They’re not substitutes for each other, and this is a common point of confusion. Home and contents insurance responds (subject to your policy’s terms and exclusions) to damage from events like storms or accidents, and commonly excludes gradual movement in reactive soils, the most frequent cause of foundation problems in Wagga. HBCF responds to contractor failure, not to the original cause of the foundation movement. See our insurance guide for the fuller comparison.
Does HBCF cover apply retroactively to old repairs?
Generally, cover is tied to the contract in place at the time the work was carried out, so a repair done years ago is governed by whatever requirements applied then, not today’s threshold or rules. If you’re relying on an old repair’s paperwork, particularly ahead of a sale, keep whatever certificate or documentation you were given at the time, and ask your conveyancer to confirm what it establishes for your current situation.
