A door closer is a device that will automatically close a door after it has been opened. It is adjustable and spring loaded, usually filled with hydraulic fluid.
They are installed for various reasons including maintaining a fire rating, preventing damage, and adding a level of security and safety to either a home or business.
Most of these door closers also come equipped with a backcheck which will prevent the door from opening too quickly by adjusting the speed of the door’s opening swing. This is to control the operation of a door in case of high winds or a someone in the middle of a temper tantrum.
A door that overswings can damage the door itself, the frame, adjacent walls, or someone who is standing in the doorway.
Door closers come in a variety of models depending on the type of door it will serve including manual doors, automatic, and electromagnetic wing.
They also come in different sizes depending on the weight and use of the door.
Some closer devices very obvious and others are more concealed.
These closers should be professionally installed to be sure they operate smoothly.
Over the years it can experience some issues.
With exposure to weather it can begin to sag or splinter.
With freeze and thaw and refreeze, it can start to buckle. Other problems might be failure to fully close, hydraulic leak, or loss of spring tension.
Some smaller items would be the door slamming or the swing cycle moving faster than usual.
When that happens, it is a good idea to schedule a maintenance visit to bring your door back into good working order.
If there is hydraulic fluid (oil) on the closer or door or floor, this is an indication that the closer has reached the end of the line.
