Builder Comparison Guide

Every builder must hold a valid licence for the type of work they are undertaking. Licensing requirements vary by state, so verify the builder's credentials through the relevant state building authority.

• Verify the builder's licence number on your state's building authority website
• Check the licence class covers the scope of your project (residential, commercial, multi-storey)
• Confirm there are no disciplinary actions or restrictions on the licence
• Ensure the builder has appropriate Home Building Compensation (HBC) cover

Adequate insurance protects you if something goes wrong during or after construction. Never engage a builder who cannot provide proof of current insurance.

• Home Building Compensation (HBC) / Home Warranty Insurance — mandatory for residential work over a threshold
• Public liability insurance — covers damage to third parties on site
• Workers' compensation — required if the builder employs staff
• Understand the statutory warranty period (typically 6 years for major defects, 2 years for minor)

A detailed, transparent quote is one of the strongest indicators of a professional builder. Be cautious of quotes that are significantly lower than others — they may exclude critical items that will be added as variations later.

• Compare fixed-price versus cost-plus contracts
• Ensure the quote includes a detailed scope of works and inclusions list
• Check what's excluded: site costs, landscaping, driveways, window treatments, fittings
• Understand provisional sums and prime cost items — these can blow out
• Ask about variation processes and how changes are priced and approved

A clear, fair contract protects both parties and sets expectations for the build timeline. Use a standard industry contract (such as HIA or Master Builders) and have it reviewed by a solicitor before signing.

• Use a standard industry contract (HIA, Master Builders, or state equivalent)
• Ensure the build timeline and milestone payment schedule are clearly defined
• Understand liquidated damages clauses for delays
• Clarify the process for extensions of time (weather, material delays, variations)

Past performance is the best predictor of future results. Ask to see completed projects and speak directly with previous clients about their experience.

• Request at least three recent references and contact each one
• Visit completed projects to assess finish quality first-hand
• Ask previous clients about communication, timeline adherence, and issue resolution
• Check online reviews and the builder's reputation in the local community

Certain warning signs indicate a builder may not be reliable. Trust your instincts — if something seems off, it probably is.

• Pressure to sign quickly or pay large upfront deposits before contract
• Reluctance to provide references or proof of insurance
• Quotes significantly below others without a clear explanation
• Vague or incomplete scope of works and inclusions
• Poor communication during the quoting phase — it won't improve during the build
