Six signs an exit door needs attention
Exit hardware has to do two jobs: let people out and leave the door secured afterward. These problems call for a closer inspection.
The bar sticks
The push bar does not move freely or return as it should. We inspect the device before deciding whether adjustment or repair is appropriate.
The door stays unlocked
The exit device releases but fails to relock after the door shuts. The latch and surrounding hardware need checking.
The door will not latch
The bar operates, but the latch does not catch. Door alignment and the strike can be part of the problem.
The door drags
A door rubbing against its threshold or frame can interfere with hardware operation. We check the door's movement and contact points.
The existing device is worn
Repeated use has left the hardware unable to operate correctly. We assess repair against a suitable like-for-like replacement.
A door cannot be secured
A failed exit device leaves a business entrance unable to lock. Call so a dispatcher can arrange emergency door-security work.
Repairs and replacements we perform
We work on the exit device and the related door hardware. The inspection establishes whether the existing assembly can be repaired or needs replacement.
Rim exit devices
We inspect, repair and replace rim-mounted exit hardware, including problems with the latch and relocking operation.
Mortise exit devices
We service exit bars connected to mortise lock bodies and check that the door releases and latches correctly.
Vertical rod hardware
We work on vertical rod exit assemblies and examine the parts that secure the door at its upper and lower points.
Compatible replacement hardware
We replace devices like for like where required to preserve a fire-rated door's rating. We service Von Duprin, Detex and Adams Rite hardware.

What affects the cost of exit hardware
The device, door condition and required work determine the charge. A technician inspects the assembly and presents a written price before repairs begin.
Device construction
Rim, mortise and vertical rod assemblies use different parts. The type installed affects repair labor and replacement hardware.
Repair or replacement
A device that can be adjusted or repaired is a different job from removing and fitting a replacement assembly.
Door and frame condition
Misalignment, worn hinges or a faulty strike can affect latching. We identify related hardware work during inspection.
Hardware requirements
On fire-rated doors, we replace hardware like for like to preserve the rating. We tell you when a fire door inspector or fire marshal is needed.
Visit and work hours
The $39 service call fee is separate. A $45 after-hours fee is added from 9 PM to 7 AM and on Sundays and major holidays.
How we get the door working again
We look at the complete door opening rather than assuming the push bar itself is at fault. The repair starts only after you approve the written price.
Describe the door problem
Call or submit a planned-work request. Our office asks for the address, door type, hardware symptoms and whether the opening can be secured.
Confirm access and authority
Our technician arrives in uniform with identification and a work card. We verify the owner, manager or authorized business contact.
Inspect and agree on the repair
We check the exit device, latch, frame and door movement. You receive a written price and approve the work before any parts are changed.
Repair, test and document
We complete the approved work, test release and relocking with your manager, provide a door record and issue an itemized invoice.
What managers ask about exit devices
An exit device is part of the door's locking hardware and its means of exit. These answers explain where our repair work begins and ends.
Call (702) 000-0000All questionsCan you repair a panic bar that will not spring back?
Yes, we inspect and service sticking exit devices. The technician checks the installed hardware and determines whether repair or replacement is needed before providing a written price.
Can you replace the bar on a fire-rated door?
We use like-for-like replacement where required to maintain the door’s rating. If the opening needs a fire door inspector or the fire marshal, we tell you. We do not guarantee code compliance.
Do you work on Von Duprin and Detex exit hardware?
Yes. Cairn services Von Duprin, Detex and Adams Rite hardware. We inspect the particular device to establish the repair scope and parts needed.
Can someone come if our exit door will not lock at night?
Yes. Emergency work to secure a failed business door can be dispatched at any hour in the Las Vegas valley. Call the dispatcher, who will give you an estimated arrival window and explain the applicable fees.
What if the bar works but the door still will not latch?
The fault may involve the strike, door alignment or other hardware rather than the bar alone. We inspect those parts as part of assessing the opening. Cairn repairs door hardware but does not replace doors, frames or glass.
