How to Vet a Builder in WA (Before You Sign Anything)
Builder insolvencies taught WA a hard lesson. The five checks that matter: financial stability, insurance, quality, timeframes and contract structure.
Western Australia learned an expensive lesson over recent years: a signed building contract is only as good as the company behind it. Builder collapses left families with half-finished homes, locked-in deposits and years of delay. Most of those clients had no idea their builder was in trouble, because nobody had looked.
Vetting a builder isn’t cynicism. It’s the same diligence you’d apply to any six-figure decision, and it comes down to five checks, all of them possible before you sign.
1. Financial stability: will they still exist at handover?
The question that matters most is the one a display home can’t answer. Useful signals:
- Time in business under the current entity. A long trading history under one ABN is worth more than a long brand history across several;
- Registration status with Building and Energy WA: confirm the builder’s registration is current and matches the entity on your contract;
- Payment behaviour in the trade. Builders in trouble slow-pay subcontractors first. Ask around the trades if you can. Suppliers and subbies know who’s stretched long before clients do;
- Volume vs capacity. A builder signing far more contracts than they historically deliver per year is financing today’s builds with tomorrow’s deposits.
None of these is definitive alone. Together, they paint a reliable picture.
2. Insurance capacity: is the safety net real?
In WA, home indemnity insurance is required for residential work over the relevant threshold. It protects you if the builder dies, disappears or becomes insolvent. Check that:
- the policy will be issued for your specific contract, in the name of the contracting entity;
- the builder can actually obtain cover: insurers assess builders’ financials, so a builder struggling to get indemnity insurance is a red flag in itself;
- you receive the certificate before paying more than the permitted deposit.
Insurance capacity is quietly one of the best financial-health signals available, because the insurer has seen the books you haven’t.
3. Quality: inspect the evidence, not the brochure
Every builder’s marketing shows their best work. You want the average:
- visit current sites, not just display homes: site tidiness, supervision and trade quality on a random Tuesday tell you plenty;
- ask for addresses of homes completed 3–5 years ago and look at how they’ve aged;
- talk to past clients if possible, and ask specifically about defect handling after handover, which is where builders differ most;
- check who actually supervises: how many jobs per supervisor, and how often they’re on site.
4. Timeframes: promised vs delivered
Ask what build time the contract allows, then ask what their actual average completion time has been over the last two years, and note the gap between the two numbers. Ask how many working days they’re claiming for weather and trade shortages, and how extensions of time are notified.
A builder who quotes an honest timeframe with contractual teeth beats one who quotes a fantasy to win the signature.
5. Contract structure: where the risk actually lives
WA building contracts are written by the builder’s side. That doesn’t make them evil; it makes them worth checking independently. The clauses that matter:
- Provisional sums and prime cost items. The smaller and fewer, the more real your price is. Big allowances mean the quote is partly a guess, and the variation risk is yours;
- Site works allowances: “subject to siteworks” has swallowed many budgets. Push for fixed-price site works after proper site investigation;
- Variation mechanics: how they’re priced, notified and approved;
- Progress payment schedule: payments should track completed stages, not calendar dates;
- Delay and extension clauses: what triggers them and what notice you get.
If reading contracts isn’t your idea of a weekend, that’s what independent contract checks are for. The cost of a professional review is noise compared to one bad clause exercised once. Contracts are stage six of the full development sequence for a reason: everything before them builds the leverage to negotiate.
Why almost nobody does this alone
Every check above is available to a determined member of the public. In practice, almost nobody does them, because the builder’s sales process is designed to feel like reassurance, and because most people have no baseline to compare answers against.
That’s the structural problem: the only party guiding you through the decision profits from one particular answer. Independent vetting flips that: the recommendation is worth something precisely because the person making it doesn’t win when you sign.
This is the vetting we run before any builder reaches a client shortlist: financial stability, insurance capacity, quality, timeframes and contract structure. If you’re comparing builders right now, book a 45-minute consultation before you sign anything.
