Who we are

Slim Line brings minimal-profile glass walls, windows & doors — frames so thin they nearly disappear — to homes across Los Angeles.

We supply and install our own Slim Line Signature line alongside the industry's leading brands, serving LA County and the Westside with pricing the big showrooms can't match.

Reviews
