Garage Door Springs do nearly all the work of lifting a garage door. The opener only guides a balanced door; the springs carry the weight. When one lets go, a 150–250 lb door becomes immovable in an instant, and it usually happens on the way out to work.
The good news is that springs rarely fail without notice. They are wound steel under enormous tension, and steel telegraphs fatigue. Here are the five signals worth acting on.
1. The door feels heavy by hand
This is the single most reliable test, and it takes thirty seconds. Pull the release cord, lift the door manually to waist height and let go. A correctly balanced door stays roughly where you left it. If it drops, the Garage Door Springs have lost tension and are no longer carrying the load they were wound for.
If the door will not hold itself at waist height, the springs are already failing. Everything else on this list is confirmation.

2. A gap in the coil
Look along the torsion spring above the door. A healthy spring is a continuous, tight helix. A visible gap of an inch or two means it has already broken — springs snap under tension and the two halves recoil apart. A door with one broken spring in a two-spring system will still open, badly, which is why people drive on it for weeks without realising.
3. Jerky travel, or one side lifting first
A door that rises in stages, shudders, or lifts unevenly at one side is telling you the load is no longer shared. On a two-spring door that usually means one spring has weakened ahead of the other, and the second is now being asked to do work it was not sized for. It will follow.
4. Cables gone slack or jumping the drum
The lift cables and the springs are one system. When spring tension drops, cables go loose, and a loose cable can unwind off its drum entirely. If you can see slack cable while the door is closed, stop using the door.
5. It has simply been long enough
Springs are rated in cycles, not years — one cycle is one open and one close. The rating you bought determines how long you get.
| Spring rating | Roughly equals | 2 cycles a day | 4 cycles a day |
|---|---|---|---|
| 10,000 cycles | Builder-grade standard | ~13 years | ~7 years |
| 20,000 cycles | Upgraded spring | ~27 years | ~13 years |
| 30,000 cycles | High-cycle spring | ~40 years | ~20 years |
Most homes run four to six cycles a day once you count everyone coming and going. A builder-grade spring on a busy family home is realistically a seven-year part, not a twenty-year one.
What to do if you spot any of these
- Stop using the opener — forcing an unbalanced door damages the motor and the panels.
- Do not attempt to unwind or replace a torsion spring yourself. The stored energy is genuinely dangerous.
- Always replace springs in pairs. A new spring next to a fatigued one fails again quickly.
- Ask for the cycle rating you are buying, not just a price.
Why we replace both
Customers often ask us to change only the broken spring. We will not, and it is not an upsell. Both springs were wound at the same time and have taken the same number of cycles. Replacing one leaves a mismatched pair, an unbalanced door, and a second call-out within months. Doing the pair costs marginally more once and lasts.
Why the springs matter more than anything else
The springs carry the weight of the door. Every single time it moves.
Here is the part people tend to skip. The Garage Door Opener does not lift anything. It guides a door the springs have already balanced. That one distinction explains most of what goes wrong on a garage door.
When springs weaken, the motor starts doing work it was never built for. It runs hot, the drive gear wears, and eventually it gives up entirely.
People then buy a new Garage Door Opener and wonder why that one dies too. It is a small thing that turns into a big thing.
How to tell how much life yours have left
Springs are rated in cycles, not years. One cycle is one open and one close.
And this is usually where it goes wrong. A builder-grade spring is often rated around ten thousand cycles. That sounds enormous until you count your actual use: two cars, a school run, someone working from home, a bin trip. Six to eight cycles a day is completely normal.
At that rate, ten thousand cycles is three or four years. Not the twenty people assume.
If you know roughly when the door was fitted and roughly how often it runs, you can estimate where you are on that clock without anyone looking at it. It is a small thing that turns into a big thing.
What we check on a spring call
Every visit runs the same way, whatever the original complaint was. It is quicker than it sounds, and it stops us treating a symptom and calling it a fix.
- Coil condition along the full length of both springs — gaps, surface rust, fatigue.
- The cycle rating originally fitted, so we can tell you honestly how much life you got.
- Cable condition at the drums, because cables and springs wear on the same clock.
- Drum set screws and shaft bearings, which is where an uneven door usually begins.
- The balance itself, by hand, opener disconnected. That is the proof the job is right.
If something on that list is worn but not urgent, we say so and give you a rough idea how long it has left. That way you can plan instead of react. We say that from experience, not from a brochure.
The mistake we see most
Replacing one spring and leaving the other in place.
It sounds obvious. It is not. Both were wound on the same day and have done the same number of cycles. Change one and you have a brand new spring working alongside a tired one.
The balance is off from day one, and the second one goes within months.
It costs a little more to do the pair once. It costs a great deal more to do it twice. That is not a sales line. It is just how the hardware behaves.
The short version
If you take one thing away from all of that: a door that is balanced, lubricated and has working safety reverses will outlast one that is not. By years, not months.
Almost everything we get called out to was preventable. Most of it was cheap to prevent, too.
So if any of this sounds like your door, get eyes on it while it is still an inconvenience rather than a breakdown. We would rather do the small job.
