Door Closer Problems

There can be undue pressure or sturdiness in a door closed if the installation was not done properly. If you are not a professional and take up this task on your own, there can be potential flaws in the placement. Then, depending on the construction of the door, for example, if it is made of glass, a problem with the door closer can translate to a bigger problem if the entire door might need replacement.

  • Withstand heavy winds is not the task for a light-duty door closer. It cannot just damage your door closer, or even break it; it can break the door itself. The tiny arm supporting the tension and pressure can snap apart, resulting in the door to slam hard and even break around the frames. Therefore, applying a door closer should start with the intended application.
  • Light duty door closers are more appropriate for an indoor setting while areas where you have frequent hurricanes and gale-force winds, you are in trouble. For the main doors that directly face the winds, using a heavy-duty door close, in some cases more than one is a necessity. While in an office inside a building, in front of your personal cabin, light-duty door closers are more than sufficient because they are just to close the door behind a person.

  • It can result in warped doors, shattered glass, slamming of doors, and frame damage. If the door closer was installed right when installing the door, the problems can grow with time, and within a few months can affect the opening and closing of the door itself.
  • Some low and cheap quality door closers do not have the proper functionality and parts. For example, you would want your door closer to at least have a dead stop.
  • The dead stops are small rubber parts that keep the door from opening any further, like small bumpers. The rubber helps to soften the blow against the arm of the closer as well. This allows it to increase the tension and avoid overextension of the closure.
