Door & Dock Service Across California

California facilities rely on a mix of high-speed doors, sectional doors, rolling steel doors, and loading dock equipment to keep freight moving. InSev Tech services and repairs the major brands installed across the state, from high-traffic distribution centers to cold storage and manufacturing plants.

We repair and maintain Rytec high-speed doors — including fabric, rigid, and spiral doors — replacing motors, belts, panels, and controls to restore uptime in temperature-sensitive and high-cycle environments. For loading docks, we service and repair Rite-Hite dock levelers, vehicle restraints, and dock seals, addressing hydraulic failures, lip and deck wear, restraint misalignment, and safety interlock issues. We also repair and install Clopay sectional and rolling steel doors, handling spring, cable, roller, track, and operator problems across commercial and industrial buildings.

Our technicians carry common parts and have direct experience with Kelley, Blue Giant, Cornell Iron, Janus, Wayne Dalton, and other leading manufacturers. Whether the equipment is brand new or legacy, we diagnose it, document the work, and keep it running.
