Choosing a builder involves checking credentials, the proposed work and the contract. Clear records and realistic questions help you compare quotes and understand responsibilities.
Check credentials and insurance
Verify that the contractor is authorised for the work. NSW home building compensation cover generally applies to residential projects over $20,000 including GST, subject to exemptions. Where required, check project-specific cover before paying money or work starts; it is not a universal insurance requirement for every tradesperson and job.
Ask about relevant experience
Discuss comparable completed projects and references. Ask what the builder did on each job rather than relying only on photographs. Confirm how design, approvals and construction will be coordinated.
Clarify subcontracting
Builders may use specialist subcontractors. Ask who will perform the work, who supervises it and who remains responsible under your contract. Using subcontractors does not by itself establish that a builder is unsuitable.
Read the written scope
Compare inclusions, exclusions, allowances, payment stages and variation procedures. Ask how delays and defects will be dealt with. Obtain advice on unfamiliar terms before signing and keep the contract and subsequent changes together.
