Chicago Door Closers Keeping Commercial Doors Operating Safely and Reliably
Most Common Reasons to Replace a Door Closer | Chicago Door Closers
The Most Common Reasons to Replace a Door Closer
Commercial door closers are designed to provide years of reliable service, but like any mechanical device, they eventually wear out. Replacing a failing door closer at the right time can improve safety, security, and overall door performance.

Below are the most common reasons a commercial door closer may need replacement.
1
Oil Leaking From the Door Closer
One of the most obvious signs of a failing door closer is hydraulic oil leakage. Door closers use hydraulic fluid to control the speed and force of the door. When internal seals fail, oil begins to leak from the closer body, causing the door to close improperly.
  • Door slamming shut
  • Inconsistent closing speed
  • Failure to latch properly
  • Visible oil on the closer body
In most cases, a leaking door closer should be replaced rather than repaired.
2
The Door Slams Shut
A properly functioning door closer should allow the door to close smoothly and safely. If the door suddenly begins slamming shut, the closer may have lost hydraulic pressure or suffered internal damage.
  • Damage door hardware
  • Damage frames
  • Damage glass storefront systems
  • Create safety hazards for building occupants
3
The Door Does Not Latch Properly
When a door closer can no longer generate enough closing force, the door may stop short of the frame and fail to latch.
  • Security concerns
  • Energy loss
  • Building access issues
  • Fire door compliance problems
While adjustment may solve some latching issues, older closers often require replacement.
4
Excessive Wear and Age
Most commercial door closers operate thousands of times every year. Over time, internal springs weaken, hydraulic seals wear out, and adjustment valves become less effective.
Even if the closer still functions, replacing an aging unit can prevent unexpected failures and costly emergency repairs.
5
Broken or Damaged Closer Arms
Closer arms can become damaged due to heavy use, abuse, doors being forced open, or loose mounting hardware.
In some cases the arm can be replaced. However, if the closer body is also worn or damaged, replacing the entire closer may be the best long-term solution.
6
Incorrect Door Closer Installation
Many commercial doors are equipped with closers that are undersized or improperly installed.
  • Door closes too fast
  • Door is difficult to open
  • Door does not latch consistently
  • Excessive stress on hinges and hardware
Installing the correct commercial-grade closer can dramatically improve door performance.
7
Building Renovations or Code Compliance
Property owners often replace door closers during:
  • Building renovations
  • Tenant improvements
  • ADA upgrades
  • Fire door inspections
  • Hardware modernization projects
New commercial door closers can improve accessibility, safety, and reliability.
8
Frequent Service Calls
If a door closer requires constant adjustment or repeated repairs, replacement is often more cost-effective than continued maintenance.
  • Better performance
  • Lower maintenance costs
  • Improved reliability
  • Longer service life
