The hardware that keeps a door working
The trouble may be in the lock, the closer or the way the door meets its frame. We inspect the moving parts before recommending a repair or replacement.
Panic bars and exit devices
We service rim, mortise and vertical rod exit devices, including bars that stick, fail to release or do not relock.
Learn moreDoor closer repair and replacement
We adjust surface closers for closing and latch speed, and replace closers that have lost their hydraulic oil.
Learn moreCommercial rekeying
We rekey existing commercial cylinders when suitable, so old keys stop working without replacing the entire lock.

Six signs the door needs attention
A door can look intact and still have a hardware fault. These are the problems our commercial technicians inspect and repair.
Door slams or misses the latch
A closer may need its closing or latch speed adjusted, or the door may be out of alignment with the strike.
Oil around the door closer
Oil escaping from the closer indicates a failed hydraulic unit. Cairn replaces leaking closers rather than treating an adjustment as the repair.
Panic bar sticks or fails to relock
An exit device that binds or fails to relock needs its mechanism and connection to the latch inspected.
Storefront door drags
A dragging aluminum storefront door may need work at its pivots, hinges or alignment with the threshold.
Key turns but bolt stays put
The cylinder may turn without operating the locking mechanism. We inspect the lock before deciding which parts need work.
Lock will not hold shut
A latch that will not engage can leave a closed door unsecured. The lock, strike and door position all need checking.
Know which part controls the door
A commercial door is a set of working parts. When one part fails, another can appear broken even when it is working correctly.
The door closer controls closing speed. Hinges and pivots support the door and guide its swing. The exit device releases the latch when pressed. The lock or deadlatch controls locking. The strike receives the latch, while the latch guard protects that area. At the floor, the threshold and door sweep seal the gap.

The diagram shows common hardware locations; the parts fitted to your door depend on its existing construction and hardware.
Exit doors need the right hardware
Exit devices and fire-rated doors must retain their required rating and meet the fire code. Cairn replaces hardware like for like and tells the customer when a fire door inspector or the fire marshal is needed. No guarantee of code compliance is made.
- Like-for-like replacement where required
- Fire-rated door requirements respected
- Inspector or fire marshal referrals when needed
From inspection to a tested door
Commercial repairs start with the door itself. We identify the fault, explain the work and test the hardware with your manager before closing the job.
Describe the door problem
Call or submit a planned service request. Tell us which door is affected, what the hardware is doing and who can authorize the work.
Inspect the door and hardware
A technician examines the door, its frame and fitted hardware to locate the fault and determine the appropriate scope.
Review the written proposal
We explain the recommended work and provide a written price. Your authorized contact approves it before repairs begin.
Schedule the hardware work
We arrange the approved repair, including after-hours scheduling when business operations require it.
Repair and check each component
The technician adjusts, repairs or replaces approved hardware, then checks the door's movement, latching and locking with the manager.
Hand over the door record
You receive a door-by-door record of the work, along with an itemized invoice showing labor, parts and the service call fee.
What determines the repair price
A sticking latch and a failed exit device are different jobs. We quote the service call fee before dispatch and set the repair price after inspection.
Type and grade of hardware
The fitted lock, closer or exit device determines which repair parts and replacement components are suitable.
Number of affected doors
A single opening and a building with several faulty doors require different amounts of inspection and labor.
Door and frame condition
A door that has shifted or binds against its frame may need alignment work alongside the hardware repair.
Repair or replacement
An adjustment uses different labor and materials from fitting a new closer, lock or exit device.
Visit time and service fees
The $39 service call fee is separate. Work between 9 PM and 7 AM, on Sundays or major holidays carries an additional $45 after-hours fee.
Door repairs for working properties
From office entrances to warehouse doors, Cairn works with the owner, manager or authorized contact responsible for each property.
Regular checks for heavily used doors
For businesses with several doors, our maintenance program provides a yearly or twice-yearly visit to inspect, adjust and lubricate door hardware.
Choose an inspection cycle
Arrange one or two visits a year, based on the property's doors and maintenance needs.
Check locks and latches
Every door's lock is inspected, adjusted and lubricated during the maintenance visit.
Inspect closers and exit bars
We check closer operation and exit device movement, making adjustments and lubricating hardware as appropriate.
Examine hinges and alignment
Hinges are inspected, adjusted and lubricated, and each door's alignment with its frame is checked. Repairs needed go on the written list.
Receive a written repair list
We document the doors that need further work. Program pricing is set per door after a walkthrough.
A restaurant exit hardware example
Sample project for this demonstration website, showing the inspection and repair of an exit door at a restaurant in an older Arts District building.
Exit hardware for an Arts District restaurant
The exit bar was sticking and the door was not relocking. The exit device and latch were inspected, the repair identified, and the door and exit device tested with the manager.

Questions before a commercial door repair
These answers explain what Cairn can repair, how approval works and when a door problem falls outside our scope.
Call (702) 000-0000All questionsCan you fix a panic bar that sticks when someone pushes it?
Yes. We inspect and service rim, mortise and vertical rod exit devices. The technician checks the mechanism and its latching operation before recommending repair or replacement.
Can you adjust a door closer that slams or closes too slowly?
We adjust closing speed and latch speed on surface-mounted closers. If the closer is leaking hydraulic oil, replacement is the appropriate service.
Do you repair aluminum storefront doors?
We service storefront locks, deadlatches, pivots, thresholds and related hardware. We can also inspect a door that drags or does not meet its latch correctly. We do not replace the door, frame or glass.
Can you repair an automatic sliding entrance?
No. Cairn does not service automatic sliding doors or their operators. Our commercial door work covers mechanical locks, exit devices, closers and related hardware.
Can you work on a fire-rated door?
We use like-for-like parts where required to preserve the door’s rating. If the opening needs a fire door inspector or the fire marshal, we will identify that requirement. We do not guarantee code compliance.
Can a manager approve the repair if the owner is not there?
Yes, when the manager is authorized to approve work for the business. Cairn verifies the business contact’s authority, and lock changes require authorization from the business. The written price must be approved before work starts.
What happens if you need to order a replacement part?
Some commercial hardware requires a special-order part, so not every job can be finished on the first visit. We identify the required work after inspection and arrange the approved replacement. Any change to the agreed scope requires a new written price before work continues.
