Common questions

What is Home Building Compensation insurance in NSW?
It protects you if the builder dies, disappears or becomes insolvent before finishing or fixing defects. It is required for residential work over $20,000, and the builder must give you the certificate before taking a deposit.
When should I hire a builder instead of a handyman?
A builder is the right starting point for an extension, structural change or a project involving several building trades. Small non-structural repairs may suit a handyman.
Who organises plumbers and electricians on a building job?
That depends on the contract. Ask whether the builder coordinates the licensed trades or expects you to engage them separately.
