Built on a simple idea.
Premium slim-frame systems shouldn't come with a premium-showroom markup.
A new kind of window & door company for LA.
Slim Line Windows and Doors Inc. was founded in Los Angeles in 2024 by people who had spent years around high-end glazing — and kept seeing the same thing: homeowners paying showroom prices for systems that could be sourced and installed for far less, without giving up an inch of quality.
So we built the company we wished existed. We manufacture our own Slim Line Signature line, carry a curated group of trusted brands, and install everything with our own local crews. One team from first measure to final walkthrough — no middlemen, no inflated markups.
Slim Line by the numbers.
Support from first sketch to final panel.
Free in-home consultation
We measure on site, review your plans or ideas, and give you a clear, itemized quote — usually within one business day.
Title 24 & performance guidance
Every system we quote is checked against California Title 24 energy code, with NFRC-rated glazing packages matched to your project.
Value engineering
Working from architect's plans? We run alternate configurations across our brands to hit the look you want at a better number.
Licensed installation
Our own trained crews handle demo, install, flashing, and finish — insured, code-compliant, and clean.
Less frame. More view.
Traditional windows put an inch or more of frame between you and the outdoors. Slim-frame systems shrink that to a narrow line of thermally broken aluminum — so a wall of glass reads as glass, not as a grid.
- Narrow sightlines for uninterrupted views
- Jumbo panel sizes for true floor-to-ceiling walls
- Modern, high-end aesthetic that suits LA architecture
- Strong thermal and acoustic performance ratings
