Specializing in residential and commercial door installation under CSLB license #836342 (D28), Pro Door San Diego operates from Queen Avenue in La Mesa's Casa de Oro area. The D28 specialty spans residential entry, interior passage, sliding patio, and pet-door installations, a scope that complements the overhead garage-door work performed by Open Sesame Garage Doors and Gates. Commercial projects include fire-rated hollow-metal assemblies, ADA-compliant automatic operators, and storefront aluminum-frame systems for tenant-improvement buildouts. Entry-door replacements often coincide with re-keying and deadbolt hardware upgrades, a locksmithing phase coordinated with the security services of Key Maker Locksmith. All installations carry a limited-lifetime warranty covering both materials and workmanship. Highest-specification projects involve UL-listed fire-rated door and frame assemblies rated up to 90 minutes, complete with smoke-gasket seals and self-closing hardware meeting CBC Chapter 7 egress requirements.
