What it is
A small shop that cuts aluminum extrusions to size, assembles frames, fits glass and installs the finished windows. Typical jobs are custom sizes, replacements and small commercial storefronts.
Your first three steps
- Set up accounts with aluminum extrusion and glass suppliers and compare their prices and lead times
- Visit local contractors and remodelers to ask what sizes or repairs they struggle to source, and get a trial order
- Price a small rented unit and the key tools (miter saw, crimper, glazing tools), and check zoning with your city or county
Who pays
General contractors, remodelers, property developers, landlords and homeowners who need non-standard sizes.
How it makes money
Quoted price per window or per job covering materials, glass, labor and installation, with repeat work from a few reliable contractors.
Skills that help
- Measuring accurately and reading plans
- Metalworking and assembly with hand and power tools
- Quoting jobs and managing customers
