Why You Need A Door Closer

Posted on: 05.04.2019 Posted by: Door Controls Direct

Essentially, a door closer is a device which closes a door automatically, either after it opens mechanically or after someone has manually opened it. According to current regulations, they should be fitted onto any fire doors, to ensure that they always close correctly after opening, unless the fire door only opens into a cupboard.

Doors closers are available in all price ranges, including budget models as well as the more expensive ones. They can also be fitted to a multitude of different door types including both manual and automatic doors and electromagnetic open/shut swing varieties.

There are many different types of door closers available, including concealed ones, so if your concern is maintaining clean and modern lines without having the mechanism showing then there is certainly a type available for you. This short list will give you a rough idea of the types available:

Type of Closer View Closers:
Surface-Mounted Overhead Door Closers
Concealed in-frame Concealed Door Closers
Concealed in-floor Floor Springs
Concealed in-door Concealed Door Closers

In all situations and circumstances your door closer should be fitted by a professional; if fitted incorrectly it may as well not be there at all!

So what is the purpose of a door closer?

  • Fire doors should be kept closed at all times – a door closer ensures that the door will mechanically close automatically after it has been opened.
  • Most closers feature dampers which offer a level of control over the force and speed at which the door closes. This cushion is especially crucial on particularly heavy doors.  Correctly adjusting the closure speed can prevent an injury to a small child or a less physically able person; in fact, anyone who is unable to move quickly, even someone burdened with heavy shopping for example.
  • A door closer will ensure that your entrance door has closed securely after someone passes through it. This prevents your property being left vulnerable to thieves etc.
  • Most closers have a backcheck facility which prevents the door from being opened too fast.  This can happen on external doors during high winds etc. when the door could blow open at high velocity:

The door blowing open at high speed could damage either the door or the doorframe itself, which is obviously costly.

  • A door blowing opening quickly could hurt anything or anyone who is standing close by as it happens.

Once you have fitted a door closer then it must be checked and kept well maintained and/or adjusted periodically.

When do you need to replace a door closer?

As with anything mechanical, there will even come a time when you will need to replace your door closer. For example, if the following occurs:

  • If you notice the door is no longer closing fully and adjustment has not solved the issue. The purpose of the closer is to ensure that the door is closed during a fire or to prevent someone getting into your home. When it is failing to do its job it’s time for a new one!
  • Equally, if the door is slamming – It is possible that the hydraulic fluid or oil has leaked out or the valve seals are worn. If adjustment doesn’t work… then it’s replacement time.
  • If the door closer has no spring tension then the spring is broken and replacement is necessary.
  • If you notice hydraulic fluid leaking, even slightly.  Without this essential fluid, the door will fail and this could happen at the point that you need it the most.
  • To keep your fire door closed thereby keeping smoke and fire at bay and allowing you to exit the premises safely.
  • To prevent any unauthorised person gaining access to your property/premises either when you are there or in your absence.
  • To prevent injury, to anyone or anything, from a very heavy door.

The number one reason why you need a door closer is for safety.
