San Diego Glass Inc. has operated from Alpine Boulevard in Alpine since 1972, running a roughly 15-person glazing operation that spans commercial storefront installation, hydraulic door-closer service, bullet-resistant glass fabrication, and automotive windshield replacement. Vehicles needing concurrent mechanical repair alongside glass service route to Woodside Automotive on Maine Avenue in Lakeside, which handles engine, brake, and suspension work that often accompanies collision-related glass damage. The commercial division installs plate-glass storefronts, aluminum-frame curtain walls, and safety-tempered display windows for retail buildouts along Alpine Blvd and throughout East County San Diego. Interior refurbishment projects that pair new storefront glass with booth and seating upholstery coordinate with Winter Gardens Auto Upholstery on Winter Gardens Boulevard for commercial and automotive interiors. Continuous operation at the same Alpine Blvd address since 1972 has built the shop's inventory to include flat glass, laminated safety glass, insulated units, and custom-cut tempered panels for both residential and commercial applications.
