Estimates for a small start in Canada, not guarantees.

What it is

You install sealed double or triple pane windows and doors supplied by a retailer, manufacturer or general contractor. You remove old units, fit, level, insulate, seal and finish the trim.

Your first three steps

  1. Contact local window retailers and renovation contractors to ask how they hire installers and what they pay per unit
  2. Get commercial general liability insurance and check whether you need WCB or WSIB coverage in your province
  3. Buy the core tools (levels, pry bars, sealant guns, shims, glass suction lifters) and complete a few trial installs with a company
Who pays

Window and door companies, renovation contractors and builders who sell the job but need installers. Some landlords and property managers may also hire you directly.

How it makes money

Paid per window or door installed, or by the day. Larger or awkward openings pay more, and a steady flow of jobs from one or two companies keeps your days full.

Skills that help
  • Carpentry or general renovation experience
  • Accurate measuring and levelling
  • Safe lifting and working at height
  • Reliable and tidy in customers' homes
Watch out for
  • Commercial general liability insurance, and WCB or WSIB rules for self-employed workers in your province
  • Whether your province or municipality requires a contractor licence or registration (Quebec has its own construction licensing, check with the RBQ)
  • Fall protection and safe ladder or scaffold use on upper floors
  • Older homes may have lead paint or asbestos-containing materials, check the rules before disturbing them
  • Winter work: cold weather limits when you can open up a house and when sealants cure properly
  • Depending on one company for work is risky, so try to have at least two sources
