What it is

You remove old windows and doors and fit new vinyl ones for companies that sell them. You supply the labor, tools and a vehicle. The company handles sales, measuring and ordering.

Your first three steps

  1. Work a few months with an established installer or take a manufacturer's installation training course to build experience
  2. Check your state and city rules on contractor licensing and get general liability insurance
  3. Contact local window dealers, remodelers and property managers and offer a trial job
Who pays

Window dealers, remodeling contractors, home improvement companies and property managers who need reliable installers.

How it makes money

Usually a set price per window or door installed, or a day rate. More jobs per week means more income, and a second installer lets you take bigger jobs.
