How to Adjust Garage Door Springs and Cables
If your garage door uses extension springs — typically mounted along the horizontal tracks — it also relies on cables that run through pulleys and connect to the bottom brackets. These parts help keep the door balanced during operation.
When the cables become loose, worn, or misaligned, the door may lift unevenly or move in a jerky way. In some cases, small adjustments can be made by moving S-hooks or cable clips to a different hole in the hanger bracket to gently increase or decrease spring tension.
If you see any visible damage, stop and contact a professional — it’s safer to let a trained technician handle it than to risk injury or make the problem worse. Visit our page on garage door spring repair to explore the types of systems 24H Garage Doors services.

Frequently Asked Questions
How can I tell if my garage door springs are properly balanced?
Pull the emergency release cord, usually a red handle near the opener track, to disconnect the door from the opener, then manually lift the door until it's halfway open. Let go and watch what happens: if the door stays in place, your springs are likely in good shape, but if it falls or shoots upward, the tension needs adjustment.
Can I safely adjust the extension springs and cables myself?
Extension springs are typically mounted along the horizontal tracks and rely on cables running through pulleys to the bottom brackets. In some cases small adjustments can be made by moving S-hooks or cable clips to a different hole in the hanger bracket to gently change tension. However, if you see any visible damage, stop and contact a professional rather than risk injury or make the problem worse.
Is adjusting a torsion spring something I should try on my own?
No. Overhead doors typically use torsion springs mounted just above the door, and because they are tightly wound and operate under significant tension, adjusting them without the right tools or training can be dangerous. Even a small mistake can cause serious injury, so this task should always be handled by qualified technicians like those at 24H Garage Doors.
If I find the tension is off, should I tighten the spring myself?
While tightening a spring can seem simple in theory, in practice it's a job best left to those with proper training and tools. If your tension test shows the springs are off, it's safer to have a professional handle the adjustment than to attempt it yourself.
