What it is
A leaner version: you order pre-cut profiles or kits, assemble and glaze them in a small garage or shared space, then install them on site. You build to order without a full machine shop.
Your first three steps
- Find suppliers that sell pre-cut aluminum window kits and glass, and ask about minimum orders and lead times
- Build one sample window and photograph it to show prospective customers
- Contact a few remodelers and handymen who may need a subcontractor for window work, and check what license your state requires
Who pays
Homeowners, small builders, remodelers and landlords who want replacement or custom-size windows.
How it makes money
Price per window or job, covering kit, glass, labor and install, with a markup on materials.
Skills that help
- Careful measuring and assembly
- Basic carpentry and installation skills
- Customer service and quoting
Watch out for
- Contractor or installer licensing varies by state and city, check before you take paid jobs
- Running assembly from a home garage may need a home occupation permit and must respect HOA or lease rules
- Building and energy code compliance for the windows you install
- Lead-safe work rules (EPA RRP) in pre-1978 homes, check if they apply
- General liability insurance and a warranty plan for leaks or faulty fits
