Strength and sightline
Steel windows and doors
Unmatched strength and timeless elegance. Superior security and fire resistance, and slim profiles that let a single opening carry far more glass than a heavier frame would allow.
Steel detailsBuilder's Window Supply · Sorrento Valley, San Diego · Since 1996
Family owned in Sorrento Valley since 1996. Six materials and six manufacturers, sold to San Diego builders, architects and homeowners, and delivered to the job.
Quality. Creativity. Craftsmanship.
This is a real job supplied out of the Sorrento Valley showroom: dark aluminum sliders running the width of a hillside room. Almost every decision a window order asks of you is visible somewhere in this frame, and working through them in front of the actual material is what the counter is for.

The material list
Nobody stocks six lines to be thorough. They exist because a coastal elevation, a security door and a budget-led remodel are three different problems, and the frame is where each one gets solved. Start with the opening, not with the brochure.

A recent project
A La Jolla custom contemporary home: Fleetwood windows and doors, TrustILE walnut interior doors, a mahogany custom entry pivot door, and a louvered mahogany and steel screen facade.
“Dave and his crew over at Builder's Window Supply are the BEST. Always available to answer my questions and their delivery times were much faster than anticipated. Professional, courteous and I wouldn't hesitate to refer him. Even my contractor is referring him to people.”
“We had four estimates. Builders wasn't the cheapest, but won our business with professional knowledge, attention to detail, quality products, and excellent communication. Of the four companies, Builders was the only one to send both a sales rep (Nathan) AND an installer (Bryon, Bella Vista) to the initial survey of our home. No sales pitch, just discussion of requirements and the attributes of products available to meet them.”
