What to check before you hire

Worth checking yourself
Only a few public reviews are shown. Ask for recent references you can contact.
Their public evidence comes from a single source. Look them up on another site before deciding.
No credentials are shown here and the business has not claimed this profile. Ask to see certificates and insurance directly.
Trade and building licensing in Australia is set by each state or territory. Check the relevant regulator (e.g. NSW Fair Trading, QBCC in Queensland, VBA in Victoria) that the contractor holds a current licence for the work type and value before you hire.
For larger residential building work, confirm the contractor carries the home-building / domestic-building insurance your state requires before you pay a deposit. It is what protects you if the work is left unfinished or defective.
Ask to see a portfolio of completed work like yours, plus recent references you can contact.
