What it is

Adding blown-in insulation (cellulose or fibreglass) to attics and to wall cavities in existing homes, plus air sealing and basic ventilation checks. Work is done at the customer's house with a blowing machine carried in a truck or van.

Your first three steps

  1. Take a short course or shadow an insulation installer to learn building science, and check what your province expects for training or certification
  2. Price used or new blowing equipment, a work vehicle and safety gear, then get quotes for commercial general liability insurance
  3. Contact local renovation contractors, real estate agents and energy auditors to offer your services, and put together a simple quote template
Who pays

Homeowners wanting lower heating bills and more comfort, landlords, and renovation contractors who sub out insulation.

How it makes money

Fixed quote per job, based on area and the insulation depth (R-value) needed. Air sealing and extra ventilation work can be added. Busiest in fall and winter, when heating costs are top of mind.

Skills that help
  • Physical fitness and comfort in tight attic spaces
  • Measuring and quoting jobs accurately
  • Basic building science (air sealing, ventilation, moisture)
  • Customer service
Watch out for
  • Commercial general liability insurance, and WCB/WSIB coverage once you hire (rules differ by province)
  • Older homes may have vermiculite insulation or other materials that could contain asbestos. Check the rules for testing and handling before disturbing it
  • Check which current federal, provincial or utility rebate programs exist and whether they require a registered or certified contractor, as these change often
  • Building code insulation requirements and any municipal business licence differ by location, so check with your municipality
  • Dust, respiratory and heat risks in attics, so plan for proper protective gear
  • Work slows in hot summer attics, so plan your cash flow across the seasons
