Commercial garage door repair · Tucson, AZ
Discount Door Service repairs commercial garage doors for businesses across Tucson, AZ and the surrounding Pima County corridors, from the Aviation Highway warehouses to the shops along Oracle and the units out past Rita Ranch. A commercial door is not a bigger version of a house door. It runs a duty cycle a residential door would never survive, it is usually the only way stock or vehicles move in and out, and when it jams half open the building is standing open with it. We work on sectional steel doors, the counterbalance and cable systems behind them, and the operators that drive them. Woman owned since 1999, licensed ROC #322606. Call (520) 579-9084 and tell us what the door is doing.

What stopped the bay
Commercial failures rarely look like residential ones. The door is heavier, it cycles far more often, and something usually hit it. These are the four calls we take most.
01
Impact damage is the failure mode a house door almost never has. A crushed bottom section will bind in the track and can pull the door out of square, so the damage spreads upward every time somebody cycles it. Sections can often be replaced individually rather than the whole door, which is the first thing worth establishing.
02
On a commercial door this is usually the counterbalance rather than the motor. The springs carry the weight; the operator only moves what the springs have already made liftable. An operator asked to lift an unbalanced steel door will burn out, and then you have two repairs instead of one.
03
This is the one that stops being a maintenance issue and starts being a security and insurance issue. Tell us that when you call, because it changes what we bring and what order we do things in.
04
Bent track, a sprung jamb, a loose header angle or a floor that has settled will all stop a perfectly good door. Replacing panels without checking the opening is how a door gets fitted twice.
A door cycling sixty times a day wears parts on a completely different timescale to one cycling four times. We ask how hard the door works, because it decides whether the right answer is a repair or a higher-rated part.
Springs, cables, drums, bearings and shaft. On a heavy steel door these are the components that make it safe to move at all, and they are checked with the door down rather than guessed at from the floor.
Photo eyes, the reversing edge and the control station. A commercial door moving with a defeated safety device around staff and vehicles is the fault we will not leave in place.
Track, jambs, header and floor. Most repeat commercial failures we see are a good door being asked to run in an opening that has moved.

What to expect
Three steps, and the priority is set by what the door is stopping.
01
Call and describe the door, the operator and what the bay is used for. If the building is standing open, say so first.
02
The technician shows you the fault, explains whether it is a section, the counterbalance or the opening, and gives you the number before any work starts.
03
The door is run under its own operator and watched through full cycles, with the safety devices checked, before we call it done.
What changes the price
Two doors that look identical from the parking lot can carry completely different hardware. Four things decide what a repair costs, and none of them can be read down a telephone line.
Commercial sections are heavier and wider, and the counterbalance is specified to the actual weight rather than a standard residential size.
Springs are rated in cycles. A part specified for a door opened six times a day is the wrong part for one opened sixty times, and fitting it is a false economy.
Impact damage is often repairable one section at a time. Whether that is true here depends on the panel profile and whether it is still made.
A commercial operator is a different machine from a residential opener, and repairing one is a different job from replacing it.
You get the price before any work starts, and nothing is replaced without you agreeing to it first.

A residential door failing is an inconvenience. A commercial door failing stops deliveries, blocks vehicles in or leaves a unit that cannot be secured overnight, and that cost usually dwarfs the repair. It is also why the cheapest-looking fix is often the wrong one: a part specified for a door that cycles a few times a day, fitted to a door that cycles all day, brings you back to the same standstill in months rather than years.

Straight answers
Often, yes, and it is the first thing worth checking. It depends on the panel profile and whether that section is still manufactured. We will tell you which it is before you commit to anything.
Tell us your hours when you call and we will be straight with you about what we can schedule. We would rather say no to a time than agree to one and leave you waiting.
Call and say that first, because it changes the priority. Do not leave the building unattended relying on the door coming down on its own, and do not force it with the operator, which usually turns one fault into two.
The most common reason on a commercial door is a part specified for the wrong duty cycle, and the second is the opening rather than the door. If the track, jambs or floor have moved, a new door fitted into them fails the same way.
Yes. The operator, the control station and the safety devices are part of the same system, and diagnosing one without the other is how a door gets repaired twice.
