When a door stops closing properly
The way a door closes tells us where to start looking. These are the problems worth having inspected before the door or its hardware takes more wear.
The door slams shut
The closer is no longer controlling the door's swing. Closing speed needs inspection and adjustment.
The latch misses
The door reaches the frame but does not catch. Latch speed or door alignment may need attention.
Oil appears on the closer
A leaking hydraulic closer is a replacement job, not something a speed adjustment can correct.
The door closes unevenly
The swing may feel controlled at first, then change near the frame. Both closing and latch speeds need checking.
Wind changes how it closes
Las Vegas wind puts extra pressure on exterior doors. We inspect how the closer manages the swing and final latch.
The door binds in the heat
Heat can expand a metal door or frame and affect the latch. The door and closer need to be checked together.
What we do to the closer
We work on surface-mounted commercial closers, checking the door's movement before deciding whether an adjustment or new unit is needed.
Set the closing speed
We adjust the main swing so the door moves toward the frame at a controlled rate.
Set the final latch speed
The last part of the swing needs enough movement to engage the latch without an unnecessary slam.
Replace failed units
When a closer is leaking or cannot operate correctly, we inspect the existing hardware and recommend a suitable replacement.
Maintain working hardware
Our commercial maintenance visits inspect, adjust and lubricate door closers once or twice a year.
What affects door closer repair costs
A $39 service call fee covers travel and inspection and is separate from the work. After inspection, you approve the written price before anything is repaired or replaced.
Adjustment or replacement
Setting the speed of a working closer differs from removing a failed unit and fitting another.
Closer type and grade
The hardware specified for the door affects the replacement part and the total cost.
Number of doors
A single troublesome entrance and a property with several closers require different amounts of inspection and work.
Door and frame condition
A dragging door or misaligned latch can require hardware adjustment beyond the closer itself.
Service timing
A $45 after-hours fee is added between 9 PM and 7 AM, and on Sundays and major holidays.
How we restore proper door closing
You know what the technician is inspecting, what the work will cost and how the door performs before the job is closed.
Tell us what the door is doing
Call or send a planned-work request. We ask for the address, door type, number of affected doors and whether they slam, leak or fail to latch.
Meet the technician
A technician arrives in a marked van with photo ID and a work card. We confirm authorization with the business owner, manager or account contact.
Review the proposed work
We inspect the closer, latch and door movement, then present a written price. Nothing is adjusted or replaced until you approve it.
Test the door together
After the work, we test the swing, final latch and lock with you. The itemized invoice separates the service call, labor and parts.
Answers about commercial door closers
The condition of the closer and the door determines what needs doing. These are the points managers usually need settled before scheduling work.
Call (702) 000-0000All questionsCan you adjust a closer that's making our door slam?
Yes, we adjust the closing and latch speeds on working surface closers. We inspect the door first because alignment and frame condition can also affect how it shuts.
Can a door closer be repaired if it's leaking oil?
A closer that leaks hydraulic oil needs replacement rather than a routine speed adjustment. We inspect the existing unit and give you the replacement price in writing before starting.
Can you replace the closer on a fire-rated door?
We replace closers on fire-rated doors like for like so the door keeps its rating. If the door needs an assessment by a fire door inspector or the fire marshal, we tell the manager.
Do you service LCN and Norton door closers?
Yes, Cairn services both LCN and Norton closers. The technician checks the particular unit and its condition before recommending adjustment or replacement.
Can you inspect all the closers at our property?
Yes. Our commercial maintenance program includes yearly or twice-yearly inspections, adjustments and lubrication, with a written repair list. Maintenance is priced per door after a walkthrough.
