Estimates for a small start in Australia, not guarantees.

What it is

You meet the customer, sketch and quote a deck, then build it with timber or composite boards. That covers footings, framing, decking, stairs and balustrades, and you may handle council paperwork or work with a certifier.

Your first three steps

  1. Check with your state's building licensing body what licence or registration you need for the size of deck jobs you want to take
  2. Get public liability insurance (and any required home warranty cover), plus a set of quote and contract templates
  3. Build a small portfolio with a few discounted or local jobs, photograph them, and ask for reviews on Google and local Facebook groups
Who pays

Homeowners upgrading their backyard, landlords improving rental properties, and people selling who want to add appeal.

How it makes money

Fixed-price quotes per project, built from materials, labour and a margin. A deposit and progress payments help cover material costs.
