Commercial Doors on the O'Hare Side of Des Plaines
A dock door that will not open does not stop a door, it stops the trucks. That is the whole calculation on commercial work, and it is why the useful conversation is about how soon the bay is back in service rather than about the door itself.

Des Plaines has a mix most suburbs do not: warehousing and freight operators on the airport side of town, service trades and auto shops along the arterials, hotels and light industry out toward Rosemont, and older commercial buildings closer in with doors that have been repaired far more often than replaced.
Rolling Steel and Sectional Fail in Different Ways
A rolling steel service door has no sections and no tracks in the residential sense. The curtain winds onto a barrel over the opening with its counterbalance hidden inside that barrel, so the failure list is short: a tired barrel spring, a damaged bottom bar, or slats a forklift has bent until they stop feeding cleanly into the guides. Sectional dock doors fail along familiar residential lines, only heavier — springs, cables, rollers, and a bottom section that absorbs every impact in the building.
The repair path differs accordingly. A bent slat can often be replaced within the curtain rather than recurtaining the whole door. A commercial torsion spring is specified by cycle rating first and weight second, which is the reverse of how a residential door is worked out.
A Dock Door Opens More in a Month Than a House Door Does in a Year
That is why cycle rating is the number that decides everything on commercial work. A standard residential spring is rated around 10,000 cycles. A busy dock door can spend that in a year, which is how a building ends up with a spring failure every winter and a manager who concludes the doors are junk.
Specifying to the real duty is what stops it: high-cycle springs, heavier hinges, sealed rollers and an operator matched to the traffic. We count openings with the tenant rather than estimating them, because the estimate is always low.
Fire Doors, Drop Tests and a Written Record
A rolling steel fire door spends its working life held open by a fusible link or an alarm-triggered release. Take that restraint away and gravity is supposed to bring the curtain down on its own. Proving it still will means dropping it deliberately and resetting it, at intervals, and it is the line most often absent from a building's maintenance file — because a fire door nobody has ever tested looks exactly like one that has been.
Planned work is scheduled around trading hours and dock activity, and the visit leaves a written record of what was tested, what was adjusted and what falls due next. A door blocking a bay is treated as an emergency call.

Questions
Des Plaines questions about this job
Our overhead door is jammed and the bay is blocked. How fast can someone get here?
A blocked bay goes to the front of the day where we can manage it. Des Plaines sits on the same route as Elk Grove Village, Rosemont and Mount Prospect, so the drive is short. Tell the dispatcher the door type and roughly how wide it is and the technician can load likely parts before setting off.
Do we have to replace the whole commercial door, or just the damaged part?
Frequently, yes. Individual slats can be swapped out of a rolling steel curtain, and single sections out of a sectional door where the model is still available. Where several are bent or the curtain has lost its shape, recurtaining or replacement is the more honest answer.
What does a scheduled commercial maintenance visit cover?
Spring and cable condition, bottom bar or bottom section, curtain or panel alignment, rollers and hinges, the operator and its reversing devices, chain or belt tension, and lubrication to the correct points. Findings go in writing so the building keeps a record.
