Garage Door Slamming Shut? Check Out The Possible Reasons

After years of listening to the quiet and gentle closing of your garage door, you might have jumped out of your skin the very first time you heard it slamming shut. That loud slam could be an indication that something wrong is going on with your garage door and you need to get it fixed as soon as possible.

Wondering what’s happening or what is causing your garage door to slam shut? Check out the list below for some of the most possible reasons and what you can do if you happen to experience them.

Malfunctioning Springs

One of the most common culprits of garage doors slamming shut is faulty springs. The springs’ primary function is to hold the overhead door’s weight and create tension so the door would slowly descend. This tension can only be done if the spring is functioning properly. But frequent high stress can eventually loose or weaken the springs over time.

Springs would typically last for 5000-2000 cycles of closing and opening and would start becoming loose once this cycle has been reached. Once the springs become very weak, they won’t be able to hold the door’s weight causing it to drop and slam on the ground.

To fix this problem, you will need to have these springs replaced. And unless you have the knowledge and experience of replacing garage door springs, it would be safer and much better to let professional technicians do it.

Loose Chains

Loose chains can also be the reason why your garage door is slamming shut. Like the springs, the chains could also become loose over time, providing lesser tension to the garage door which causes it to slam shut. If the chain looks loose or if you hear it knocking against the other parts of your garage door, you should have it replaced immediately to fix the problem.

Professional Technicians

Whatever the problem you might encounter with your garage door, it is advisable to seek the help of professional technicians. Any type of job that is related to garage doors can be dangerous if you don’t have the right knowledge and experience of the job. They also require specialist equipment for guaranteed successful repair.
