My Builder Won’t Fix Defects Under Warranty: When Should You Hire a Building Dispute Lawyer?

If your builder refuses to fix defects during the warranty period, Victorian law provides clear legal remedies — from formal written notices and government dispute resolution through to VCAT proceedings — and a building dispute lawyer can help you navigate each stage effectively.

Builder defect disputes are among the most stressful situations a homeowner can face. You have invested significantly in your property, and when a builder refuses to honour their warranty obligations, it can feel as though you have limited options. In Victoria, however, the law provides structured pathways to pursue rectification, and knowing when to seek professional legal advice is key to protecting your position.

Your Rights Under Victorian Law: Implied Warranties on Domestic Building Work

Building dispute lawyers often emphasise that contractual wording is not the final word in construction disputes. Every domestic building contract in Victoria carries a set of implied warranties that apply by law and cannot be signed away, regardless of what your contract says. These warranties exist under both the Domestic Building Contracts Act 1995 (Vic) and the Australian Consumer Law, and they apply whether or not a formal written contract is in place.

Under the Domestic Building Contracts Act 1995, your builder is legally required to carry out work in a proper and workmanlike manner, use good and suitable materials, and ensure that new homes, extensions, renovations, and repairs are suitable for occupation when completed. These rights are enforceable for up to 10 years from the date the work was completed and transfer to subsequent property owners within that period.

How Long Do You Have to Pursue a Defect Claim?

The timeframe for a defect claim depends on the nature of the defect and the legal pathway you use. Under the Building Act 1993, implied warranty rights are enforceable for up to 10 years from the date the work was completed — and this period applies whether you are the original home owner or a subsequent purchaser of the property.

Separate timeframes apply under domestic building insurance (DBI), which provides separate coverage periods for structural and non-structural defects that differ from — and are generally shorter than — the statutory implied warranty period.

It is important to understand that domestic building insurance can only be claimed where the builder has died, become insolvent, disappeared, or failed to comply with a tribunal or court order (for policies issued after 1 July 2015). If your builder is still operating but simply refusing to fix defects, the implied warranty pathway through the BPC and VCAT is the more immediate route — and legal advice can help you assess both options in parallel where relevant.

What to Do When Your Builder Refuses to Fix Defects

Victorian law outlines a structured escalation process for homeowners whose builders refuse to address defects. Working through each stage in order is generally required before formal dispute resolution at VCAT can be accessed.

1. Attempt direct resolution first. Contact your builder in writing and clearly describe the defects you believe require rectification. Putting your concerns in writing gives you a record of your discussions that may be valuable if the dispute escalates. Keep copies of all correspondence, photographs of defects, relevant contract documents, and any independent inspection reports you obtain.
2. Apply to the Building and Plumbing Commission (BPC). If direct resolution fails, you can apply to the Building and Plumbing Commission (BPC) for dispute resolution — a free service available to homeowners with domestic building disputes. Before applying, you must have taken reasonable steps to resolve the dispute directly with the builder within the last three months. The BPC can assess disputed work and issue binding dispute resolution orders. Note that disputes must not relate to building work more than 10 years old.
3. Apply to VCAT. If BPC conciliation does not resolve the matter, you may be eligible to apply to the Victorian Civil and Administrative Tribunal. For domestic building disputes involving a homeowner, VCAT generally requires that the matter has first been through the BPC (formerly DBDRV) before an application can be made, with the exception of applications for injunctions. VCAT has jurisdiction over disputes between property owners, builders, and warranty insurers.

The BPC does not have the power to settle disputes between homeowners and builders or award compensation directly. However, it can issue legally binding dispute resolution orders and certificates that enable a matter to progress to VCAT if conciliation is unsuccessful.

Documentation is critical throughout this process. Gathering an independent building inspection report, keeping a clear written record of all communications with your builder, and preserving photographic evidence of defects will support your position at each stage of escalation.

When Should You Hire a Building Dispute Lawyer?

Not every defect dispute requires legal representation from the outset, but there are clear situations where engaging building dispute lawyers in Melbourne can make a meaningful difference to your outcome.

• Your builder has ignored written notices and is refusing to engage with resolution attempts.
• The defects are extensive, structural, or materially affecting the habitability or value of your property.
• You have received a BPC decision and need advice on whether to proceed to VCAT.
• Your builder is threatening to terminate the contract or counterclaiming for non-payment
• You are uncertain whether your situation involves a warranty claim, an insurance claim, or both.
• The dispute involves complex contract interpretation or disputed variation claims.
• Statutory limitation periods are approaching, and you need urgent advice

A building dispute lawyer can help you understand your rights under the Domestic Building Contracts Act 1995, prepare and serve formal legal notices, represent you in BPC conciliation or VCAT proceedings, and assess whether a domestic building insurance claim should be pursued alongside your defect claim.

One of the most important reasons to seek legal advice early is timing. Statutory limitation periods and mandatory procedural steps — including the BPC process that must generally be completed before VCAT — mean that delay can prejudice your position. Acting at the right stage helps ensure your rights are preserved, and the escalation process is navigated correctly.

Understanding when and how to act can make a significant difference to the outcome of your building dispute. With the right advice at the right time, you can avoid unnecessary escalation and protect your position from the outset. That’s where Boutique Lawyers can assist — providing clear, strategic guidance grounded in deep experience in building and construction law. 

Understanding Domestic Building Insurance and Its Limitations

Domestic building insurance (DBI) is a mandatory protection scheme for most residential building work in Victoria. A builder is required to obtain DBI when the cost of building work under the contract exceeds $16,000, including both labour and material costs. For policies issued after 1 July 2014, DBI provides coverage of up to $300,000 per claim.

However, DBI is not a substitute for a direct warranty claim against an operating builder. DBI protects homeowners from financial losses where a builder has died, disappeared, or become insolvent — not where a builder is still operating but refusing to rectify defective work. If your builder is still trading, pursuing rectification through the BPC and VCAT under your implied warranty rights is typically the appropriate first pathway, with DBI potentially relevant as a separate avenue if the builder’s circumstances change.

Frequently Asked Questions

Can my builder refuse to fix defects if my contract specifies a short warranty period?

Potentially not. The implied warranties under the Domestic Building Contracts Act 1995 apply by law and cannot be signed away, even if your contract attempts to limit the warranty period to a shorter timeframe. Statutory implied warranty rights may be enforceable for up to 10 years from the date work was completed, and these rights transfer to subsequent property owners within that period. Whether a specific defect falls within those warranties depends on the circumstances — legal advice can help you assess your position.

Do I have to go through the BPC before I can take my builder to VCAT?

Generally, yes. For most domestic building disputes involving a homeowner, VCAT will not hear the matter unless it has first been through the BPC dispute resolution process (formerly DBDRV). The main exception is where an injunction is being sought. The BPC process is free and can result in binding orders, making it a necessary step in most cases, regardless of whether VCAT proceedings are ultimately required.

My builder is no longer operating — can I still make a defect claim?

If your builder has died, become insolvent, or cannot be found, you may be eligible to make a claim under domestic building insurance. DBI provides coverage for structural defects for up to six years and non-structural defects for up to two years from the date of completion, up to $300,000 for policies issued after 1 July 2014. A building dispute lawyer can advise on the appropriate claim strategy and whether additional pathways apply to your situation.
