Loading Dock Door Repair

Most people call it a dock door. It is usually a sectional overhead door or a rolling steel door set into the wall at dock height, with a dock leveler at the floor and a dock seal or shelter around the opening. We repair both kinds of dock door and the equipment around them.

Most loading dock doors are 8 or 9 feet wide and 8 to 10 feet high. An 8 by 9 foot door is the size seen most often, while a 9 by 10 foot door gives a forklift more room with today's wider trailers. See standard loading dock door sizes for how each one fits.

Those are dock seals: foam pads covered in heavy fabric that press against the back of a trailer to close the gap around the door. A dock shelter does the same job with a frame and curtains instead of pads. We repair dock seals and bumpers as well as the door, so one visit can cover the whole dock position.

The leveler bridges the gap between the dock floor and the trailer bed, so forklifts can drive in and out safely. On most docks it only runs with the door fully open, so a door problem and a leveler problem often show up together. We repair dock levelers too: see dock leveler repair.

Our average response is about an hour and a half, during business hours and for emergency calls at night or on weekends. We dispatch around the clock, and common springs, cables, rollers and operator parts ride on the truck, so many dock doors are back in service on the first visit.

Usually, yes. Bent sections, panels and track are straightened or replaced on their own, and the rest of the door stays in place. Until it has been checked, keep people and vehicles clear and do not run the door, because a bent section or track can let it drop.

Yes. Our technicians are licensed and insured, and a certificate of insurance usually goes out within 24 hours of your request, so a property manager or landlord can approve the job.

It depends on the door type and size, the parts that failed, and whether the operator, leveler or seals need work too. The estimate is free, and you approve one flat price before any work starts. Our repairs carry one year on labor and three years on parts.

Replace dock seals when the pads are torn, flattened or show foam, or when daylight shows around a parked trailer. Check them monthly.

A hydraulic dock leveler usually fails from lost power, low or leaking fluid, a tripped safety stop, debris in the pit or a worn lip hinge.

Replace a dock bumper when about half its rubber is worn, the pads are flush with the steel, the steel is bent or rusted, or the anchors are loose.

Schedule preventive maintenance every 3 to 6 months depending on cycle count, inspect safety devices monthly, and keep a spare parts kit on site for common wear items.

High-cycle garage door springs are heavy-duty torsion springs rated for far more cycles, sized for busy commercial doors that fail standard springs.

Yes. We run 24/7 emergency commercial garage door service across Denver, fixing most stuck or unsecured doors on the first visit with stocked trucks.

The main commercial warehouse doors are sectional, rolling steel, high-speed, fire-rated, and dock doors. Here is how each works and which fits.

A high-speed door that stops working has usually lost power, has a blocked, dirty or misaligned photo eye, had its curtain knocked out of its tracks, or has an activator, limit or drive fault; the drive, brake and controls are a technician's job.

Almost always the springs: they have lost tension, worn out or broken, or a cable slipped. Close the door, keep traffic clear and call a trained technician.

Dock levelers are sorted by mounting (pit, edge-of-dock, vertical), by drive (mechanical, hydraulic, air) and by lip. Busy docks use hydraulic pit levelers.
