Estimates for a small start in Canada, not guarantees.

What it is

You fit vinyl windows and doors that someone else sells and supplies. That means removing old units, fitting and levelling the new ones, insulating, sealing and finishing the trim. You work alone or with one helper.

Your first three steps

  1. Contact local window retailers, manufacturers and renovation contractors to ask about subcontract install work and their pay rates
  2. Get your tools, a vehicle that can carry glass units safely, and commercial general liability insurance
  3. Do a few trial installs, take photos of your finished work and ask for a written reference
Who pays

Window retailers and manufacturers, renovation contractors, and property managers who need installs done but have no crew of their own.

How it makes money

Usually a fixed price per window or door installed, or a day rate. More jobs per week means more income, and a reliable helper lets you take on bigger jobs.

Skills that help
  • Carpentry and measuring accuracy
  • Comfortable working at heights and in all weather
  • Reliable and tidy in customers' homes
Watch out for
  • Commercial general liability insurance, which suppliers often ask to see
  • WCB or WSIB registration, which may be needed even as a sole operator or once you hire (check your province)
  • Whether your province or municipality requires trade certification or a business licence for this work
  • Older homes may have lead paint or asbestos-containing materials, so check safe-work rules before cutting or scraping
  • Winter installs are slower and need extra care with sealing, and work may dry up in the coldest months
  • Check whether you are properly treated as self-employed rather than an employee, and register for GST/HST once you pass the threshold
