Estimates for a small start in Australia, not guarantees.

What it is

You install windows and doors that someone else has sold and supplied. This includes removing old frames, fitting and levelling new units, sealing and finishing. Your work comes from window suppliers, builders and renovation companies.

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. Register an ABN, get public liability insurance and sort out your tools and a work ute or van
  3. Introduce yourself to local window suppliers and small builders and offer a trial job
Who pays

Window and door suppliers, builders, renovators and project home companies.

How it makes money

Paid per window or door installed, or per day, by the companies that give you the work. Steady relationships mean fewer gaps between jobs.
