Commercial buildings depend on door closers for safety, fire protection, accessibility, and security. Whether it’s an office, school, hospital, apartment building, or retail store, a fully working door closer ensures the door closes safely and smoothly every time.
According to recent facility management reports, over 67% of commercial door failures happen due to poor maintenance or lack of routine inspection. This means that simple regular care can prevent most problems; saving businesses time, money, and safety risks.
In this Commercial Door Closer Maintenance Guide, you’ll learn how to:
- Maintain commercial door closers
- Identify common problems
- Fix minor issues
- Perform routine inspections
- Improve door safety and lifespan
1. What Is a Commercial Door Closer?
A commercial door closer is a device installed at the top of a door to close the door after someone opens it automatically. You will commonly find these in:
- Offices
- Hospitals
- Schools
- Apartment buildings
- Retail stores
- Warehouses
- Hotels
- Fireexits
Door closers help maintain security, privacy, noise control, fire safety, and climate control.
If your building uses smart locks, access control systems, or KeyItLocks commercial lock services , a well-maintained door closure is essential for proper security.
Why Door Closer Maintenance Matters
A well-maintained door closer does more than close the door. It protects people, property, and your building’s structure.
Safety
If the door closer breaks, the door can slam hard—loud enough to startle someone—and that sudden impact might injure a customer, worker, or student.
Maintains Building Security
If the door doesn’t close fully, anyone can enter.
Protects Fire-Rated Doors
In an emergency, fire doors have to swing shut on their own, sealing fast with a sharp click.
Reduces Repair Costs
Regular maintenance can extend the life of a door closer by 40%.
Better Customer and Visitor Experience
A noisy or slow-closing door creates a bad impression.
Helps with ADA Compliance
Doors must not require too much force to open.
Types of Commercial Door Closers
Different door closers may require different maintenance approaches.
1. Surface-Mounted Door Closers
The most common type is seen in malls, offices, and schools.
2. Concealed Door Closers
Hidden inside the door frame, popular in modern interiors.
3. Floor-Spring Door Closers
Used for glass doors.
4. Automatic / Hydraulic Closers
Part of an automatic door system, often paired with access control. No matter which one you have, the maintenance steps are similar.
Commercial Door Closer Maintenance Guide
Below is a simple, easy-to-follow commercial door closer maintenance guide you can use monthly or quarterly.
Visual inspection
Check for:
- Oil leaks
- Cracks
- Loose screws
- Rust
- Misalignment
If you see oil leaking, the door closer needs immediate replacement.
Leaking means the internal hydraulic system has failed.

Check the Door’s Closing Speed
A properly working closer should:
- Close smoothly
- Not slam
- Not drag
- Latch securely
There are usually two speed settings:
- Closing speed (main swing)
- Latching speed (final closing movement)
If the door closes too fast or too slow, you need to adjust it.
Tighten All Screws and Brackets
Loose screws are a common issue. Use a screwdriver to check:
- Arm screws
Mounting plate screws - Body screws
- Stopper screws
Loose screws can cause loud noises, shaking, or incomplete closing.
Lubricate Moving Parts
Use a non-oil-based lubricant on:
- Arm joints
- Pivot points
- Metal attachments
Do NOT lubricate hydraulic valves.
Doing so may damage the internal system.
Check Alignment of the Door and Frame
A misaligned door creates:
- Dragging
- Noise
- Gaps
- Difficulty closing
Misalignment may be caused by:
- Loose hinges
- Heavy usage
- Building settling
- Weather changes
If the door rubs against the frame, fix hinge alignment or call a technician.
Test the Fire Safety Function
Fire doors must close:
- Fully
- Automatically
- Without someone pushing it
If your building has fire doors, this test must be done every 6 months or as required legally.
Check for Noise Issues
A healthy door closer should operate quietly.
If you hear:
- Grinding
- Squeaking
- Clicking
- Popping
- Whistling
…it means the closer or hinges need attention.
Noise often means the door is wearing out.
Here are quick solutions for the most common issues.
