Safety first: garage door springs and the cables attached to them hold enough tension to cause serious injury. Spring and cable adjustment, winding and replacement should be done by a trained technician. Call Tampa (813) 461-6009 or Largo (727) 275-2888, 24 hours a day, or see garage door spring repair.

An up-and-over garage door relies on a finely tuned spring system to make it easy to lift and lower. Over time, these springs can lose their tension, causing the door to feel heavy, uneven, or difficult to operate. Restoring that tension is a job for a trained technician, because the springs store enough energy to cause serious injury. This guide explains why tension matters, the warning signs, and when to call for help.

Part 1: The Safety Check – Why Proper Tension Matters

It’s important to understand why proper tension matters. A properly balanced door should be easy to lift and should stay open on its own at any point in its travel.

  1. Inspect the Springs: An up-and-over door typically has springs located on either side of the horizontal tracks. Visually inspect them for any signs of rust, damage, or wear. If a spring is broken, do not attempt to adjust it. A broken spring is a dangerous situation that requires professional replacement.

When to call a professional

If you have a broken spring, or the door is heavy, uneven or will not stay open, call a professional garage door technician. The springs are under a lot of pressure, and a mistake can lead to a serious injury.
