Estimates for a small start in Australia, not guarantees.

What it is

Installing loose-fill insulation such as cellulose or glasswool with a blowing machine, mainly in roof spaces with awkward access and in wall cavities. A two-person crew works from a van or truck.

Your first three steps

  1. Talk to machine and material suppliers about equipment, training and what installers typically need to get started
  2. Check your state's licensing and insurance requirements, then set up your ABN, insurance and a vehicle suitable for the machine
  3. Introduce yourself to builders, renovators and energy-efficiency assessors, and offer to quote a few of their jobs
Who pays

Homeowners doing retrofits, landlords, builders and renovators, and owners of small commercial buildings.

How it makes money

Priced per job by area and depth of insulation, with materials included. The machine lets a crew cover large areas faster than batts.

Skills that help

  • Calculating coverage and depth accurately
  • Managing a small crew and scheduling jobs
Watch out for
  • Licensing differs by state and territory, so check with your local licensing body before quoting
  • Equipment is a big upfront cost, so consider leasing or buying second-hand
  • Public liability and workers compensation insurance once you have staff
  • Dust, fibres and asbestos in older buildings, so use proper PPE and get a hazard check on pre-1990 homes
  • Check that products meet Australian Standards and suit your climate and building type
