Commercial Garage Doors

Commercial garage doors face demands that residential doors never encounter: heavy daily use, extreme weather exposure, security requirements, and the need for minimal downtime. Castle serves warehouses, auto shops, fire stations, loading docks, retail storefronts, and more across San Diego and Riverside County.

Commercial Door Types

• Sectional overhead doors — the most common commercial type, available in insulated and non-insulated versions
• Rolling steel doors — coil up above the opening, ideal for limited headroom
• Fire-rated doors — meet fire code requirements for compartmentalization
• High-speed doors — rapid open/close for high-traffic areas, reducing energy loss
• Security grilles — ventilated security for retail and storefronts

What Commercial Customers Need

Commercial doors are judged on uptime. A door that is down closes a loading dock, blocks a service bay or leaves a storefront exposed, so the priorities differ from a home: cycle rating, security, and how quickly it can be serviced. About 20% of Castle’s work is commercial — warehouses, auto shops, fire stations, loading docks and retail across San Diego and Riverside County.

How We Approach a Commercial Installation

• Site assessment: opening size, headroom, traffic pattern, and whether the door needs to be insulated, fire-rated or high-speed
• Door and operator matched to the duty cycle, not just the opening — a door that cycles dozens of times a day needs different hardware than one that runs a few
• Installation scheduled around your operating hours to minimize downtime
• Dock equipment, security grilles and access control installed alongside the door where needed

After Installation

Commercial hardware wears faster than residential. Annual maintenance keeps springs, cables, rollers and operators within spec and catches problems before they stop the door. Every installation carries our 1-year labor warranty; the manufacturer’s warranty on the door itself varies by model, and we handle any manufacturer claim for you.
