From Delays to Defects: How to Handle Building Issues in WA

05 March 2026

Building your dream home is exciting, but things don’t always go as planned. Whether it’s delays, defective workmanship, or disputes with your builder, encountering issues during your build can lead to many sleepless nights. The good news is that there are pathways for addressing problems, protecting your interests, and ensuring your build stays on track.

Document Everything

If you notice a problem during your build, start by documenting everything related to the issue:

  • Take photos of defects or issues
  • Keep records of emails, texts, and messages with your builder
  • Note dates of when problems occurred and any verbal discussions

Having a detailed record is crucial if you need to escalate your complaint later.

Communicate Directly With Your Builder

Most issues can initially be resolved through direct communication. Contact your builder promptly and explain your concerns clearly and politely. Also be clear about what outcome you expect – a repair, replacement, or compensation.

Many reputable builders in Perth are willing to fix mistakes promptly, especially if you provide clear evidence and a reasonable timeline. While it’s easy to become emotional about potential costly mistakes or issues, staying calm and professional will help to ensure a productive discussion and resolve things faster.

Review Your Contract

Before taking further action, review your building contract. Western Australian contracts generally outline:

  • The scope of work
  • Responsibilities of the builder
  • Processes for dispute resolution
  • Warranties and guarantees

Understanding your contractual rights can help you determine whether the builder is failing to meet their obligations. Knowing your rights allows you to approach discussions from a position of knowledge rather than frustration.

Contact Your Builder’s Warranty Insurance Provider

In WA, builders are required to provide home warranty insurance for residential projects valued over $20,000. This insurance can cover you if the builder cannot complete the work or rectify defects. If your issue falls under this category, contact the insurance provider as soon as possible and provide them with your documentation. This is an important step for protecting yourself during building disputes in WA.

Seek Advice

Several organisations can provide guidance and support when disputes arise:

  • Building Commission WA – Oversees builders’ licensing and standards. They can advise on your rights and assist with complaints regarding licensed builders.
  • Consumer Protection WA – Offers resources for resolving building disputes and tips on mediation or legal action.
  • Housing Industry Association (HIA) – If your builder is a member, the HIA can offer guidance on resolving issues fairly.

These organisations are key contacts for anyone navigating building disputes in Perth and can help you explore resolution options before escalating to formal complaints.

Lodge a Formal Complaint

If direct communication doesn’t resolve the issue, you can lodge a formal complaint with the Building Commission WA or Consumer Protection WA. The Building Commission handles complaints against licensed builders, especially regarding poor workmanship, contract breaches, or unlicensed activity, while Consumer Protectioncan assist in disputes, and if needed, facilitate conciliation or take matters to the State Administrative Tribunal (SAT). When lodging a complaint, include your documentation, a clear timeline, and the resolution you’re seeking. This improves your chances of success.

Consider Mediation or Legal Action

If all else fails, you may need to engage a mediator or take the matter to SAT. Mediation can often resolve disputes without lengthy court processes. SAT can make legally binding decisions if your builder refuses to comply with contractual obligations. For complex cases, consulting a solicitor experienced in building law in Perth is advisable. They can help navigate legal requirements and ensure your rights are protected.

Prevention is Better Than Cure

While problems can arise, many disputes are preventable. Some tips for a smoother build include:

  • Check your builder’s credentials with the Building Commission WA
  • Get detailed contracts outlining every aspect of the project
  • Conduct regular site inspections and communicate concerns early
  • Retain all documentation from quotes to plans and approvals

Being proactive minimises risk and ensures you have the necessary evidence if problemsoccur.
