Since 1972, San Diego Glass & Door has served as a San Diego commercial in Grantville at 6549 Mission Gorge Road, Suite 107, providing storefront installation, glass repair, window replacement, and door service across the 92120 ZIP since 1972. The company has operated under the same ownership with over 50 years of combined field experience, and the service scope centers on commercial properties: retail storefronts, office building curtain walls, restaurant entrance systems, and industrial facility glazing. Commercial door and storefront hardware upgrades pair with access-control installations, and Hi-Tech Lock & Key in Grantville handles the electronic strike plates, panic bar replacements, and commercial-grade deadbolt systems that complement new storefront door installations. Emergency board-up service covers broken storefront glass, shattered entry doors, and vandalized window assemblies, with same-day temporary plywood or polycarbonate sheeting followed by permanent glass replacement once the insurance adjuster approves the scope. The glazing product range includes tempered safety glass, laminated security glass, insulated dual-pane units for energy code compliance, and ballistic-rated panels for high-security applications in financial institutions and government offices. Hydraulic door closer replacement and adjustment is a recurring service line — commercial entry doors cycle thousands of times per month, and closer bodies rated to the ANSI/BHMA A156.4 standard require periodic valve adjustment or full replacement to maintain controlled closing speed. Metal fabrication for custom storefront frames and curtain wall mullions coordinates with area ironwork contractors, and M & P Iron Works and Fencing Inc. in College Area handles the structural steel framing that supports large-span glass installations. The Mission Gorge Road location places the shop within Grantville's auto and trade-services corridor near SDSU, with direct delivery access to commercial properties throughout San Diego County.
