Commercial Door Closers
When a closer fails, your door slams, props open, or won't latch. We fix and replace commercial door closers across North Dallas, same day.
Commercial door closer repair is the service of fixing or replacing the overhead or concealed hydraulic unit that controls how your business door swings shut and latches. A worn closer leaks oil, slams the door, or leaves it hanging open, which breaks fire-code compliance and security. An Apex Locksmith Pros tech diagnoses the closer on site, adjusts or swaps it, and tunes the closing and latching speed before leaving.
- Free on-site assessment of the closer, arm, and mounting
- Speed and latch adjustment so the door closes and seals correctly
- Like-for-like replacement with LCN, Norton, or Dorma closers when needed
- Fire-rated and ADA-compliant options matched to your door
Commercial work is quoted up front after the on-site assessment. No flat menu price.
How Commercial Door Closer Repair Works
We come to your business, find why the closer is failing, and fix or replace it on the spot.
- 1
On-site assessment
A tech checks the closer body, arm, mounting plate, and door alignment to see if it needs adjustment, a rebuild, or full replacement.
- 2
Repair or replace
We adjust the valves if the unit is sound, or swap in a matching closer like an LCN 4040XP or Norton 7500 when it's leaking or stripped.
- 3
Tune and test
We set the sweep, latch, and backcheck speeds, confirm the door latches under its own power, and check fire and ADA closing force.
- 4
Pay what you heard up front
Adjustment or full swap, the bill is the number quoted after the assessment.

Frequently Asked Questions
If the body is sound and only the speed is off, we adjust the valves. If it's leaking oil, won't hold an adjustment, or the arm is stripped, replacement is the only reliable fix.
Yes. A fire-rated door has to close and latch under its own power to do its job, and a failing closer is a common code violation. We tune or replace the closer so the door self-latches every time.
The closer's sweep or latch valve has usually drifted, or the unit is low on hydraulic fluid. We can re-tune a healthy closer or replace one that's leaking.
Yes. We stock delayed-action and adjustable-force closers that meet ADA opening-force limits, and we set the closing speed so the door is easy to open but still latches.
We're mobile across the 20 North Dallas cities we cover, with techs typically arriving in about 20 to 30 minutes from our McKinney base.
