What we check and repair
- Observation of the complete opening and closing cycle.
- Inspection of the closer body, arm, mounting and visible leakage or damage.
- Checks of sweep speed, latch speed and backcheck where the installed closer allows adjustment.
- Checks of hinges, pivots, alignment, threshold contact, strike and latch engagement.
Repair or component replacement is likely when
Adjustment or repair is used when the closer and surrounding opening remain serviceable and the true source of resistance or speed can be corrected.
Full replacement or installation may be better when
Closer or other component replacement is recommended only after the failed part is confirmed.

Questions about Door Slams or Closes Too Fast
Why does my commercial door slam shut?
A closer may be out of adjustment or failing, but hinge resistance, alignment, wind, mounting and latch setup can also change the closing cycle. The full opening should be checked before one part is replaced.
Can a door that closes too fast be adjusted?
Often yes, when the closer remains serviceable and the door moves freely. Adjustment is not reliable when the closer leaks, is damaged or is fighting a misaligned door.
When does the door closer need replacement?
Replacement may be appropriate when the closer leaks, is physically damaged, cannot hold adjustment or is incompatible with the door and mounting conditions.
Can you install a new door closer?
Yes. Once the door, weight, width, traffic and mounting conditions are confirmed, we can install a compatible new closer and test the closing and latching cycle.
What if the door cannot close or lock today?
Use Commercial Entrance Failures or call the emergency line when the business cannot secure the entrance safely right now.
