Is It Safe for Me to Repair My Own Garage Door Spring?

Mar 1, 2019 | Maintenance


It’s an unmistakable sound – the snap of a spring or the crash of a door. It’s the sound you least want to hear as you get ready to leave the house. If you haven’t heard it, consider yourself lucky.

No, it’s not a cheap horror movie trick. It’s a metal garage door spring snapping under tension. You’ll know it’s broken completely when you go to open your door and find that it’s struggling to lift itself up.

You may think you can repair this yourself. It’s a spring. How hard can it be? It turns out that replacing a garage door spring on your own can be extremely dangerous. It could even end up costing you more in the long run. There are several things to consider before attempting to fix a broken garage door.


Regardless of style or design, there are only two types of springs in modern overhead doors. Knowing what type of spring you have is the first step for anyone attempting to repair a broken spring.

Torsion Springs are responsible for the getting your garage door up when you open it. This single spring is mounted at the top of a garage door and covered in a tube. The tube is there to prevent further damage to your door or spring system if a break should occur. When these fail, you will hear a loud bang that sounds like a firecracker and see an immediate failure to open the garage door. This spring twists itself in order to gain enough power to lift the door. This spring will be relatively thick and directly above your door opening.

Extension Springs are found in an extension spring system. They essentially do the same thing as tension springs, but the process to get your garage door opened and closed is slightly different. Extension springs stretch or elongate in order to gain enough power to lift the door. These two springs will be relatively thin and run parallel to each door track.

Both of these types of springs build up tension when your garage door is closed. The energy stored up should then allow the garage door to open with ease. This isn’t the case when a spring breaks. Instead of building up energy, a snapped spring loses all of the stored energy it needs to lift the heavy door. Both springs still have a level of tension that could be potentially dangerous if worked on by someone unfamiliar with spring systems and garage door repair.


Extension and torsion springs can only be used for a limited number of open/close cycles. The cycles range anywhere from 10,000 to 20,000 opens (up to 10 years with proper maintenance) depending on the quality of your door.

Because of how long they last, it’s unlikely that a DIY homeowner has any experience with spring repair or replacement in residential garage doors. Luckily, we have plenty of experience!


When an inexperienced person tries to work with loaded springs and a weighted door, chances are that they haven’t considered everything that could go wrong. If the springs have any tension left in them and are handled improperly, they could snap and cause bodily harm.

In addition to the possible physical injuries, improper handling of springs could lead to further property damage or permanent damage to your garage door and its spring system.

Extension springs are considered to be slightly safer to work with because you don’t actually have to deal with the spring tension. However, this doesn’t mean the problems cannot still happen. It’s best to call a certified technician when working with extension springs to make sure there are no issues with the repair.

Torsion springs are extremely dangerous to work with if you don’t have much experience with them. There are many steps to replace a torsion spring, meaning that there are many opportunities for issues to come up. We recommend that you always call for professional service if you have torsion springs because of how tough they are to work with.

If you aren’t sure what type of spring you have, we can help you figure it out!


In short, we recommend that you do not open your door at all when a spring breaks. This prevents any damage to the door, you or anything else.

However, we know that leaving your car or other possessions in a garage door that won’t open isn’t ideal. It won’t work for everyone. If you must open it, carefully open your door manually and make sure that it is secure at the top of your garage before pulling out. You will then have to slowly close the door manually from the outside – this is the most dangerous part, and we do not recommend it. Unless you know for certain that the safety cable is still in working order, you should not try this.

In these cases, we recommend you call us for emergency service to get your garage in working order on the same day. This guarantees that you get a certified and qualified technician from Garage Doors of Indianapolis and prevents any harm to you or your property.

Your security is our priority. The longer your garage door remains stuck or out of your control due to broken springs, the more you are inconvenienced. We want to make sure you get all of your garage door issues solved in a timely manner.

We are available 24 hours a day for emergency commercial and residential service whenever anything malfunctions with your garage door.


You absolutely can! The best way to prevent your spring system from breaking is to schedule regular garage door service and maintenance with the certified technicians at Garage Doors of Indianapolis.

Regular maintenance ensures that your springs are always inspected and replaced before they break.
