Estimates for a small start in Australia, not guarantees.

What it is

You measure up, remove old frames and install new uPVC (vinyl) windows and doors, including sealing, flashing and finishing, on jobs passed to you by others.

Your first three steps

  1. Check your state's licensing body to see what licence or registration you need for window and door installation
  2. Get public liability insurance, register an ABN and put together a basic tool and lifting kit
  3. Contact local uPVC window suppliers and small builders to offer trial installs and ask about regular subcontract work
Who pays

Window suppliers and manufacturers, builders, renovators and property managers who need a reliable installer.

How it makes money

Fixed price per window or door, or a day rate. Steady work from a few regular contacts keeps your diary full without chasing homeowners.

Skills that help
  • Carpentry or glazing experience
  • Accurate measuring
  • Safe lifting and working at height
  • Reliable and tidy on site
Watch out for
  • Building or trade licensing differs by state and territory, and often depends on the job value, so check before quoting
  • Public liability insurance, and check your state's rules on warranty or home warranty insurance
  • Heavy glass and working at height create injury risk, so plan for two people on larger units
  • Relying on one or two clients for all your work can leave gaps, and check payment terms
  • Workers compensation insurance is needed once you hire staff
