Why Functional Door Closers Are Essential for Your Business
A door closer controls closing movement, but the closer, hinges, door alignment and latch need to work together. If a commercial door slams, will not latch or is difficult to use, describe the symptoms and share the closer model. We assess the hardware and explain the appropriate work.

Common Door Closer Problems and How We Fix Them
Over time, door closers can develop various issues that compromise their performance and your building’s safety. At Mile High Locksmith, we specialize in diagnosing and repairing a wide range of door closer problems. Here are some of the most common issues and how we resolve them:
Incorrect Door Closer Installation
- The closer model and mounting must suit the door. We assess the existing hardware and door operation before recommending an adjustment or replacement.
Low Lubricant Levels and Oil Leaks
- A leaking closer needs assessment. Replacement or manufacturer service may be needed. Allegion states that LCN closer fluid must not be refilled in the field; we do not promise an on-site oil refill.
Misaligned Doors and Frame Damage
- Door alignment, hinges and frame condition can affect closure. We identify the issue and explain the work we can perform and whether other repair is needed.
Locking and Security Issues
- If the door does not latch or lock, describe what happens. We assess the closer and locking hardware before recommending work.
Adjustment, replacement or manufacturer service may be appropriate depending on the model and fault. We confirm the available work and parts before scheduling.

When to Call a Professional for Door Closer Repair
Knowing when to call a professional for door closer repair can save you time, money, and potential safety risks. Here are some signs that it’s time to bring in the experts:
- Oil Leaks: If you notice oil dripping from your door closer, it’s a clear sign that the internal seals are damaged. This can lead to improper door movement and faster wear on the mechanism.
- Difficulty Opening or Closing: If your door is too hard to open or slams shut, the closer may need adjustment or repair.
- Misaligned Door: A door that doesn’t close evenly or leaves gaps can indicate frame damage or an improperly installed closer.
- Unusual Noises: Grinding, squeaking, or other unusual sounds suggest mechanical issues that require immediate attention.
- Locking Problems: Difficulty locking your door may point to misalignment or a malfunctioning door closer, compromising your building’s security.
Follow the manufacturer’s service instructions for the exact closer. A leaking or damaged unit may need replacement or manufacturer service. Arrange an assessment before attempting repairs to internal components.
If you’re experiencing any of these issues, don’t wait—contact Mile High Locksmith today for prompt, expert service.
