How to Make a Master Build Guarantee Claim

    If you’ve discovered defects in your new home or your builder has failed to complete the work, your Master Build Guarantee may provide protection. However, many homeowners don’t realise that strict time limits apply when making a claim. Missing these deadlines could affect your ability to have your claim considered.

    This guide explains the steps involved in making a Master Build Guarantee claim and what you should do if you believe you’re covered.

    Step 1: Check That Your Home Is Covered

    Before taking any further action, confirm that your project is covered by a valid Master Build Guarantee.

    Locate your guarantee certificate and check:

    • The guarantee number
    • The type of cover provided
    • The issue you’re experiencing is covered
    • The guarantee is still valid

    If you’re unsure, contact Master Build before proceeding.

    Step 2: Notify Master Build As Soon As Possible

    One of the most important parts of the claims process is notifying Master Build within the required timeframes.

    If your claim relates to defective workmanship or materials, you generally need to notify Master Build within 90 days of discovering the defect.

    If your claim relates to builder insolvency or non-completion, you generally need to notify Master Build within 30 days of becoming aware of the issue.

    After notifying Master Build, you’ll normally be required to submit the official claim form within 14 days.

    If you’re unsure whether your issue is covered, it’s usually better to contact Master Build early rather than risk missing a notification deadline.

    Step 3: Give Your Builder an Opportunity to Fix the Problem

    In most situations, you should first notify your builder about the issue and give them an opportunity to rectify the defect.

    Keep all communication in writing where possible.

    Include:

    • A description of the defect
    • Photos
    • The date it was discovered
    • What outcome you’re seeking

    Saving emails, letters and text messages may help if your claim progresses further.

    Step 4: Gather Supporting Evidence

    The more evidence you have, the easier it may be to assess your claim.

    Useful documents include:

    • Photos and videos
    • Building contract
    • Plans and specifications
    • Council inspection records
    • Code Compliance Certificate (if applicable)
    • Independent building reports
    • Invoices
    • Emails and correspondence

    Organising your documents before lodging a claim can save time later.

    Step 5: Submit Your Claim

    Once you’ve gathered your documentation, complete the official Master Build Guarantee claim form and submit it with your supporting evidence.

    Be prepared to provide:

    • Your guarantee number
    • Property address
    • Builder’s details
    • A description of the issue
    • Copies of supporting documents

    Master Build may contact you for additional information or arrange an inspection before making a decision.

    Important Information About Contractual Disputes

    It’s important to understand that the Master Build Guarantee is not designed to resolve contractual disputes between homeowners and builders.

    If there is a disagreement about payments, variations, delays or other contractual matters, those issues may need to be resolved separately before a Guarantee claim can be fully assessed.

    If you’re unsure whether your issue relates to the building contract or the Guarantee itself, consider obtaining independent legal advice.

    Common Reasons Homeowners Make a Claim

    Some of the more common reasons include:

    • Defective workmanship
    • Structural defects
    • Weather-tightness issues
    • Builder insolvency
    • Failure to complete the project (where covered)
    • Other defects covered by the specific Guarantee

    The exact cover depends on the type of Master Build Guarantee issued for your project.

    Final Thoughts

    If you believe your home is covered by a Master Build Guarantee, don’t delay. The Guarantee contains strict notification timeframes, and acting promptly can help protect your rights.

    Keep detailed records, communicate with your builder in writing, and gather as much supporting evidence as possible before lodging your claim.

    If you’re unsure about your options, contacting Master Build early is generally the safest approach.
