Bay stuck half open? Discount Door Service handles commercial garage door repair for businesses in Tucson, plus Oro Valley and Marana, from the Aviation Highway warehouses to the shops along Oracle. We fix sectional steel and roll-up doors, the torsion springs, cables and drums behind them, and the operators, photo-eyes and safety devices that drive them. A commercial door runs a duty cycle a house door would never survive, so we diagnose it on site and you approve the price up front.

Why the bay went down
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
A crushed bottom section binds in the track and can pull the door out of square, so the damage spreads every time somebody cycles it. Sections can often be replaced individually, and that is the first thing worth checking.
02
On a commercial door this is usually the counterbalance, not the motor. The springs carry the weight. An operator asked to lift an unbalanced steel door will burn out, and then you have two repairs instead of one.
03
This stops being a maintenance issue and becomes a security and insurance issue. Tell us that first when you call, because it changes what we bring and the order we do things in.
04
Bent track, a sprung jamb, a loose header angle or a settled floor will all stop a good door. Replacing panels without checking the opening is how a door gets fitted twice.
Price your bay repair
Describe the door and what it is holding up, from deliveries to a locked unit. Rather talk it through? Phone (520) 579-9084 around the clock and a person answers, not a machine.

On a commercial call
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.
Real person, day or night
02
Your technician points out the fault, explains whether it is a section, the counterbalance or the opening, and quotes you a firm figure before a wrench turns.
Fault shown, then priced
03
The door runs under its own operator through full cycles, with the photo eyes and reversing edge checked, before we call it done.

When we do the repair
Two bay doors that match from the parking lot can hide very different springs, sections and operators. Four things set what a commercial repair costs, and we only see them on site.
01
Commercial sections are heavier and wider, and the counterbalance is specified to the actual weight rather than a standard residential size.
02
Springs are rated in cycles. A part built for a door that moves six times daily is the wrong part for one that moves sixty times, and fitting it is a false economy.
03
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.
04
A commercial operator is a different machine from a residential opener, and repairing one is a different job from replacing it.
The number comes before the tools come out, and no part on your bay door is swapped until you say yes.
Shops and warehouses
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 why the cheapest 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.

Commercial FAQ
Urgent bay question? Call us at (520) 579-9084
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. A bay call after closing is billed at our normal rate.
Call (520) 579-9084 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, control station and safety devices work as one system, and diagnosing one without the other is how a door gets repaired twice. Our garage door opener repair page covers the operator side.
Four things set it: how big and heavy the door is, how many times a day it cycles, whether one section or the full door is damaged, and the operator. Finding the fault on our visit is free when you approve the repair, and the price comes on site before work begins.
Yes. Along with sectional steel doors, we fix light commercial roll-up doors and the springs, cables and operators behind them. Tell us the door type when you call so we bring the right parts.
Yes. Discount Door Service holds Arizona Registrar of Contractors license ROC #322606 and carries a bond and insurance. Woman owned and family run, our team has served Tucson since 1999.
