Commercial Door Closers: Replace or Repair?

DK Hardware -

Most door closers come equipped with mechanisms to assure automatic closing and protect the door from opening too wide or being blown open by the wind. Although door closers are generally reliable and robust, they frequently require expert attention. They usually go unnoticed until they malfunction. These door closers seldom break, but they need proper lubrication to keep operating smoothly and adjustment to compensate for internal wear. However, even after trying these steps, the door fails to close correctly; it's time to change the door closer.

When to Install a New Commercial Door Closer

  1. When there is no existing door closer present
  2. When the door closer is not working properly
  3. Your client has requested one, or you have added access control to the door
  4. The door is a fire door, and a door closer is required to pass inspection

When to Repair Your Commercial Door Closer

  1. After installing a new lock or access control unit on the door, you may notice problems where the door does not close completely, or there are other functional issues with how the door allows the door to swing either when opening or closing.
  2. If the problem is an adjusting screw or a damaged arm which can be repaired, then do that. If the door fails to work correctly even after fixing, it is likely internal damage and needs to be replaced.
  3. If this was an existing installation, you might need to verify that the door closer was correctly installed in the first place. If this is the case, then you need to check out a few things:
  4. Position of the closer and the shoe
  5. Determine if the arm was properly preloaded
  6. There are hydraulic valves that need to be adjusted properly

When to Replace Your Commercial Door Closer

  1. If you find hydraulic fluid on the closer, door, or the floor, it indicates that the door closer has reached the end of its service. If adjusting the valves has no apparent effect on the behavior of the door closer, it might indicate replacing it would be appropriate.
  2. If your door closer has suffered damage, it might be time to replace it.
  3. The door closer is supposed to control the door at all times. If it is not doing this task properly, you should upgrade to a better and more robust model.
