Hiring a builder

Bathroom renos sit above the licensing threshold in every state (NSW $5,000, QLD $3,300, etc.). You need a licensed builder or trade contractor with the right scope. Verify:

  • Contractor licence number on the state regulator’s register
  • Home Warranty / Home Building Compensation insurance (required for residential jobs above the threshold)
  • Public liability insurance
  • Written contract (Master Builders or HIA standard, not the builder’s own)
  • Fixed quote or schedule of rates with contingency clauses
  • Paint progress payments to milestones, not arbitrary
  • Pay no more than 10% deposit

Get three quotes. Don’t take the cheapest if it’s missing inclusions like waterproofing or Certificate of Compliance. Don’t take the dearest if you can’t see why it’s more.
