When you find yourself standing in your garage with a service technician, looking up at your broken garage door spring, you will probably be asked: "Would you like to replace one spring or two?".

If your door has two springs, the quick answer is most definitely change both springs to not only save yourself money but also to prevent any more inconvenience in the near future from another broken spring.

Both springs have completed the same number of cycles which means they have the same exact amount of wear. Let's take a look at a few different scenarios and see if any look similar to your situation.

The life of a garage door spring is based on cycles. The minimum specification is 10,000 cycles. That means the garage door will go up and down on average 10,000 times before the spring breaks. The more you use your garage door, the sooner the spring will need to be replaced.

No. If your garage door was originally set up with only one torsion spring, then you are perfectly ok with having only one spring put back on the door. If your garage door has two springs pulling the door up, then definitely have both replaced. The second spring will break, it's just a matter of time which is usually within 6 months. Have both springs replaced while the repair company is there to save money.

Yes and no. Two springs will increase cycle life and help you get out of a bind when one spring breaks. Since torsion springs don't break at the same time, you can usually lift your garage door with the help of the unbroken spring that is pulling the door with the cables still in intact. The downside is two springs cost more.

If your garage door has extension springs mounted above the tracks, it is always a good idea to replace those in pairs. This will ensure the springs are pulling the door evenly as it goes up and down. If you are buying garage door springs online, you need to make sure you buy the right size for your garage door.

Your technician should be able to show you where your cable is damaged if they are recommending replacement. If it makes you feel better, you can replace the cables for a little extra insurance. That is completely up to you.

It is good practice to replace the rollers when having your springs replaced to keep your garage door in good working order.

Garage door rollers play an important role in the garage door ecosystem. When you have good rollers and they are running properly, your garage door will operate more efficiently.

Common Signs of a Broken Garage Door Spring Recap

  • Cables are loose on one side or both
  • Garage Door goes up 6" when trying to open it with your electric garage door opener
  • Garage Door is jerky when going up (you might have 2 springs and only 1 is broken)
  • Garage door falls fast when going down using the electric garage door opener (you might have 2 springs and only 1 is broken)
  • When you release the electric garage door opener from the door, the door cannot be physically lifted
  • The electric garage door opener tried to lift the door and it bent your top section
  • On extension spring setups, the door might be crooked because a spring is broken on one side

We have seen many instances where a homeowner never knew they had a broken spring on their garage door because their electric opener was strong enough to pull the door up and down with only one good spring. This is a scary situation because if anyone was to pull the red emergency release cord, the garage door would fall to the ground.

If your garage door opener is set up properly, the sensitivity should activate and stop a few inches off the ground when trying to open a door with a broken spring. This mainly pertains to garage doors that have two torsion springs because the good spring will still hold the cables in place. Otherwise, the cables on the sides would be all over the place.
