Finding defective work in your own home is stressful in a way that commercial disputes are not. You live in it.
The instinct is to get it fixed immediately, or to send an angry email. Both can hurt your position. What helps is protecting people and property, preserving evidence, checking the clock, and communicating clearly. In that order.
If there is an immediate risk to safety or ongoing property damage, take reasonable protective action. Photograph the condition before the urgent work happens, and keep the invoices, reports and removed materials where you can.
Beyond that, resist the urge to rectify. Broad rectification before the builder has been notified and the condition documented can destroy the evidence your claim depends on. It is genuinely one of the most damaging things a homeowner can do, and it is done with the best intentions almost every time.
Section 18B of the Home Building Act 1989 (NSW) implies warranties into residential building contracts.
These cover due care and skill, compliance with plans, specifications and the law, suitable materials, timely performance, and where relevant reasonable fitness for occupation. You do not need to find these in your contract. They are implied by statute.
For a major defect, proceedings for breach of statutory warranty generally must be commenced within six years from completion of the work. For other breaches, the general period is two years from completion.
Note what those run from. Completion of the work, not the day you noticed the problem. People lose claims on that distinction.
There is a limited extension. If the breach becomes apparent in the final six months of the applicable period, proceedings may be commenced within a further six months after that period ends. It is narrow, and it is not a general extension for every claim.
And the warranty period does not pause because you are talking to the builder, attempting rectification or using a complaint process. Assume the clock keeps running, because it does.
The statutory definition is specific and the classification matters, because it decides whether you have six years or two.
Broadly, it concerns a defect in a major element of a building attributable to defective design, workmanship or materials, or a failure to comply with structural performance requirements, that causes or is likely to cause specified serious consequences. Major elements can include load-bearing components, fire safety systems and waterproofing.
Classification needs careful analysis of the defect and its consequences. It is not a judgement to make from a photo.
Number every defect. Identify the room or location, describe what is wrong, record when you first noticed it, and link it to photographs.
Take wide shots for location and close-ups for detail. Include a ruler where size matters. Keep the original files with their date metadata rather than screenshots. Then build a short chronology: contract, work, inspections, completion, discovery, notices, access, rectification attempts.
A practical homeowner guide covering documentation, notification, the dispute pathway and the time limits, plus a defect schedule worksheet and a critical dates table you can fill in.
Written notice should make each issue easy to identify and give the builder a reasonable opportunity to respond.
Attach the numbered defect list and photographs. Avoid broad descriptions like “poor workmanship” without explaining the condition and location. Check whether your contract prescribes a notice method, address or timing, and use it. Ask for a written response setting out the builder’s position and proposed rectification method.
On access, you are not required to provide unlimited or uncontrolled access. But refusing reasonable access can affect your claim and your obligation to mitigate loss. Consider the builder’s proposal, qualifications, method, timing, supervision and past conduct before deciding what is reasonable.
Mr Murdock has obtained over 300 5-Star reviews from satisfied customers.
Direct resolution first. Then Building Commission NSW, a free complaint handling service that may include contact with the parties, an inspection and in some cases a Rectification Order. Then NCAT, which can hear and determine home building claims.
One warning. If your statutory warranty period is close to expiring, a complaint process may not preserve your right to commence proceedings. Lodging with NCAT in time may be necessary, and that is a point to get advice on quickly.
Document first, then get advice. If a deadline may be approaching, or the builder has stopped responding, call us on (02) 8201 0051. Leo Lawyers acts for homeowners and builders in residential building disputes in New South Wales.
