Identify the business that will enter the contract
A trading name or enquiry website may not be the same legal entity that carries out the building work. Ask who is quoting, who signs the contract and which licence applies. For Queensland projects, check the QBCC information; for NSW work, use the NSW licensing service.
Look for relevant and attributable evidence
Ask for examples that relate to the work you need, with permission to share them. Make sure a review refers to the actual business and project type. A design inspiration image is not evidence of a completed renovation.
Ask how professional recommendations are handled
Where an OT, designer or other assessor is involved, ask how the scope is reviewed and how a proposed change is resolved. A builder should identify construction constraints without replacing clinical advice.
Expect an assessment proportionate to the work
A major bathroom, ramp or structural project should not be reduced to a product price based on one photograph. Ask what has been inspected, what remains uncertain and what further information is needed.
Read the quote as a description of responsibilities
Check inclusions, exclusions, allowances, approvals, products, temporary facilities and handover documents. Ask about insurance appropriate to the work and how variations are agreed. Keep written answers with the quote.
Discuss communication and disruption
Agree who receives updates, how decisions are made and how the household can use the property during work. Construction can affect daily routines well before the final result is ready.
Verify before making a commitment
Use the relevant official register and seek professional advice where the contract or licensing arrangement is unclear. A website statement about working with a builder is not proof of the licence held by the contracting entity.
