If it fails: the first hour
What the site contact should do before the technician arrives.
- Secure the entrance manually or block it if it will not lock
- Power down an automatic operator that is malfunctioning to prevent injury
- Photograph the failure point for the service record
- Call for after-hours service if the location is closing for the night
What fails
What a service call includes
- Diagnose whether the pivot, closer, frame, or hardware is causing the fault
- Rebuild or replace the floor pivot or overhead closer mechanism
- Replace worn threshold and door sweep to restore the seal
- Replace glazing gaskets and re-set glass panels that have started to rattle
- Service or replace mortise locks, paddle handles, and push-pull hardware
- Troubleshoot and repair automatic door operators, including sensor recalibration
- Re-square and re-anchor the frame where fasteners have loosened
- Replace perimeter weatherstripping
Preventive checklist
The items a maintenance program should carry for this system. Build a combined checklist across systems with the checklist builder.
Quarterly
- Check pivot and closer operation for drag or noise
- Inspect threshold for wear or cracking
- Test automatic door sensors and activation
Annual
- Full glazing gasket inspection and replacement as needed
- Frame anchor and fastener tightening
- Lock and hardware lubrication
- Automatic operator belt and motor inspection
What it costs
| item | typical range | what moves it |
|---|---|---|
| Floor pivot or closer rebuild | $300 to $700 | Cost depends on whether the mechanism can be rebuilt in place or needs full replacement. |
| Threshold and sweep replacement | $200 to $500 | Custom-cut aluminum thresholds cost more than stock sizes. |
| Glazing gasket replacement (per panel) | $150 to $400 | Rises if the glass itself needs to be re-set or replaced along with the gasket. |
| Automatic door operator repair | $400 to $1,200 | Sensor or belt repairs run lower, control board or motor replacement runs higher. |
| Mortise lock or paddle hardware replacement | $250 to $600 | Depends on lock grade and whether it integrates with access control. |
National ranges. Local labor, access, after-hours timing and materials move them. Multi-site programs usually price below one-off calls.
When this is an emergency
A storefront entrance that will not lock at closing time, or an automatic door stuck open, counts as an emergency because it is the primary public-facing security point.
How to choose a provider
- Ask if the provider stocks common storefront pivot, closer, and threshold parts
- Confirm experience with automatic ADA door operators if the entrance is motorized
- Ask how quickly they can respond to a lock failure at closing time
- Get a quote that separates hardware, glazing, and frame work
- Ask whether they can match aluminum finish on frame repairs so patch work does not stand out
Questions
Why does the storefront door drag on one side?
Usually a worn floor pivot or a frame that has shifted slightly out of square, both of which get worse with continued heavy use.
How is a storefront door different from a standard commercial door?
Storefront doors are aluminum-framed with glass panels and typically pivot on a floor mechanism rather than side hinges, so the failure points and repair parts are different from a hollow metal door.
Why did the automatic door stop opening?
Common causes include a worn drive belt, a dead or misaligned motion sensor, or a control board fault. A technician can usually narrow it down during the first visit.
Can a cracked threshold be repaired or does it need full replacement?
Minor cracks can sometimes be filled, but a threshold that has shifted or broken through needs replacement to keep the door sealing properly.
