Can I Replace Just One Garage Door Spring?

One of the most frequently asked questions we get from homeowners is, “Can I replace just one garage door spring?”. The answer is yes but we don’t recommend it. Most garage doors operate with two springs, if that’s the case with your door then you should replace both springs at the same time. We’ll talk more about why springs matter, why you should replace both at once, and much more in this post. 

Why Do Garage Door Springs Matter?

Who would’ve thought that something as simple as a spring could be so important? Well, it’s true. Garage door systems consist of lots of moving parts and springs happen to be one of the most important elements. 

Springs matter because they act as a counterweight to the weight of the door. Again, the springs are just one part of the door system. The garage door opener’s motor moves to lift and lower the door but the door is heavy so springs act as a counterbalance. On a balanced door, the opener moves the door but the springs carry the weight. Damaged or broken garage door springs become a major problem.

Can a Garage Door Work with One Spring?

A garage door system can work with one spring if it’s a one-spring system. Most garage doors have a two-spring system and heavier doors require more than two springs. A garage door with a broken or damaged spring should not be used, especially not with an automatic opener. The door opener may still be able to lift and lower the door but running it can cause damage to the opener or cause any of the springs to break if they haven’t already.

Operating a garage door with a broken spring can cause:

  • The opener to break a gear or burn out.
  • The chain or belt to break.
  • The opener rail to bend.
  • The door to slam to the ground.

If your springs are damaged or broken you should schedule a replacement service as soon as possible. Only lift the door manually if you have no other options and preferably do so with a partner or spotter.

Types of Garage Door Springs

There are two types of garage door springs, torsion springs and extension springs. Your garage door tech will be able to identify the type of spring immediately, it’s also good to know in case you’re asked about it when you call your local garage door pros. 

Torsion Springs

Torsion spring systems are located above the garage door opening. A standard torsion spring system has one spring but it can have more if the door is heavy. Torsion springs vary in diameter, wire size, length, wind, and type of ends. The weight of your door will determine which springs will work for your door. 

Extension Springs

In an extension spring system, the springs are located near the garage door tracks with one spring on each side of the door. The heavier the door, the more springs it has. Extension springs are typically found on older doors. 

Can I Replace Just One Garage Door Spring?

So can you replace just one of the springs? Well, yes— but no garage door pro will recommend it. We know that when one spring gives, any others on the door are likely to follow. It’s best to replace all the springs at once so that you don’t have to deal with the inconvenience of another broken spring soon.
