How Torsion and Extension Springs Support Door Weight
A garage door relies on heavy metal coils to offset the weight of the panels as they move up and down. Torsion springs sit on a metal bar above the opening, while extension springs stretch along the side tracks. Over years of daily cycling, the metal gets tired and finally breaks under the built-up tension.
Recognizing a Broken Spring or Unbalanced Door
You might hear a loud bang from the garage like a firecracker when the coil snaps under pressure. A broken spring leaves the door stuck shut, or if it opens partway, you will see a visible gap in the middle of the metal coil. If the door goes up crooked or feels overwhelmingly heavy when pulled, the balance has failed.
Signs Your Garage Door Needs Spring Service
- Loud snapping sound heard from the garage
- Visible break or separation in the metal coil
- Door lifts only a few inches before stopping
- Frayed metal cables hanging loose near the tracks
- Openers struggling or stalling halfway up the track
What Happens During a Spring Inspection and Replacement
A technician checks the entire counterbalance system, including the metal shaft, end bearing plates, and lifting cables. The old broken hardware is carefully unwound and removed from the mounting brackets. A matching replacement spring is selected based on the exact weight and size of your door panels.
Check the Damage
The technician looks at the broken coils, cables, and brackets to see what parts failed.
Unwind Old Tension
Remaining tension on the metal shaft is safely released using winding bars.
Install New Springs
Fresh coils are secured to the center plate, wound to the correct tension, and tested for balance.
Can I manually open my garage door if a spring is broken?
A broken spring or loose cable makes manual lifting unsafe because the full weight of the door is unsupported. Trying to lift it can cause the door to drop suddenly or damage the tracks.
How do I know if I have torsion or extension springs?
Torsion springs are mounted on a steel bar directly above the door opening. Extension springs run horizontally along the upper tracks on each side of the garage.
Why did my garage door spring break?
Springs have a limited number of cycles based on daily use and age. Temperature shifts and lack of basic lubrication can also cause the metal to wear out sooner.
