Torsion spring replacement is the repair of the springs mounted on the shaft above the door, not the springs stretched along the tracks. If you heard a bang from the garage and the door now barely lifts, tell Jack’s about those two symptoms together. A visible gap in the spring above the opening is another useful observation. Avoid running the opener again or approaching the shaft to measure the damaged spring.
Sizing the replacement
Door weight, spring dimensions and the counterbalance arrangement determine a suitable replacement. A similar-looking spring is not enough. Our assessment includes the existing door and any previous changes that could affect its weight, such as replacement sections or added material.
Check the lifting system together
A spring failure can leave the lifting system out of balance. The technician checks the related cables, drums and mounting hardware before returning the door to operation. If your door has a pair of springs, discuss the condition and replacement scope for both.
Approve the repair before work starts
The estimate identifies the recommended parts and labor. Jack’s provides a 90-day repair warranty covering the work and parts we replace. Let us know if the door is your only garage access or a vehicle is trapped.
Parts of this job
The job covers the torsion springs, the shaft and cones they use, and the drums the cables wind on, matched to the door that is there. The door stays out of use until that system is assessed. This page stays in the index because torsion work is its own request.
What is a different job
Extension spring replacement is a different job and keeps its own page for springs that run along the horizontal tracks. The broader broken-spring page is a different starting point when you do not know which type failed. Opener repair is a different job when the door is balanced and the motor will not run.
Your questions, answered.
Will a stronger opener solve a broken spring?
No. An opener is not a substitute for the door’s counterbalance system. The spring fault needs professional attention before normal operation resumes.
Can I order a spring from a photo?
A photo can help identify the arrangement, but it cannot establish the full specification. Spring selection requires measurements and an assessment of the actual door.
Should I use the extension-spring page for a bar above the door?
No. A shaft above the opening is this torsion job. Extension springs are the different job along the side tracks.
