My fire door won't latch on its own. Is that a problem?

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.

Why does my door slam shut so hard?

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.

Do you carry ADA-compliant closers?

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.

How fast can you get to my business?

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.

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. Our mobile techs diagnose the closer on site, adjust or swap it, and tune the closing and latching speed before we leave.

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.

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.
