Licences and rules to check
Who may do the work depends on the state. In Victoria, a door and window licence allows professionals to carry out projects over A$16,000, and you must appoint a registered builder for balcony work when the project costs more than A$10,000 including labour and materials. In Queensland, glazing and installing glass worth more than A$3,300 needs a glass, glazing and aluminium licence, and security screen installers need a carpentry contractor licence. Ask to see the licence number before you agree on a price.
Season and timing
Australia's seasons run opposite to the northern hemisphere: November is late spring, summer lasts from December to February and winter from June to August. Work booked now gives you time to compare offers before the summer months, when you will use the room most. Wet weather in winter can delay external work, so allow extra time for balcony or outside door fitting in those months.
How it is bought here
Measure each opening in millimetres: width, height and the depth of the wall reveal, because installers and suppliers quote metric sizes. Ask whether the price includes removing the old frame, making good the wall and the product itself, and whether labour is shown as a separate line. Name your city and suburb, so that sellers in Sydney, Melbourne, Brisbane, Perth or Adelaide quote for the right area.
What to write in your request
Say how many windows or doors you need and the dimensions of each opening. Name the work (replace, supply and install, or install only), whether you or the installer supply the product, and any extra work such as making good the wall. Give the site address, your deadline and your budget. A photo of the opening helps sellers judge the job before they quote.
