What it is

You install windows and doors that others have sold, working as a subcontractor for window dealers, home improvement companies, and remodeling contractors.

Your first three steps

  1. Check your state's rules on licensing or registration for installers and subcontractors
  2. Make a short list of local window dealers and remodelers, and ask if they need installers
  3. Get general liability insurance and a basic kit of tools and ladders, since dealers often ask for proof of coverage
Who pays

Window dealers, remodeling firms, and general contractors that need extra installers.

How it makes money

Paid per window or per door installed, or by the day. Steady work from one or two firms keeps your schedule full.

Skills that help
  • Carpentry and trim work
  • Fitting windows accurately and neatly
  • Reliability and time-keeping
  • Working safely at height
Watch out for
  • Contractor license or registration rules for subcontractors, which vary by state, so check your state licensing board
  • EPA lead-safe (RRP) certification may be needed for pre-1978 homes, and some firms require it
  • Worker classification: check IRS rules on being an independent contractor versus an employee
  • Depending on one or two firms for most of your work is risky, so line up a backup
  • Payment terms and callbacks for rework, so confirm them before starting
