Watch a Pro Replace a Broken Garage Door Torsion Spring (Uncut)

Published October 2, 2026 · By Dean Regev, Integrity Garage Doors & Gates · 3:59 video

This is what a broken torsion spring replacement actually looks like. The footage is from a real Integrity Garage Doors & Gates service call, shown uncut from the moment the tension is released to the final test of the door, with Dean (the owner) explaining each step as it happens. Some parts of the footage are sped up so the whole job fits in about four minutes.

We put it online so homeowners can see what goes into the job — and why it is a job for a trained technician with the right tools, not a weekend project. If your door won't open and you heard a loud bang from the garage, start with our guide on how to tell if your garage door spring is broken.

Why This Isn't a DIY Job

Watching a pro do it can make spring replacement look simple. It isn't. Here is what the video doesn't make obvious:

• Extreme tension. A wound torsion spring stores enough energy to lift a 150- to 300-pound door. If a winding bar slips or a set screw isn't tight, that energy releases in a fraction of a second — the bar becomes a projectile and the torsion tube can spin violently.
• Special winding bars. Springs are wound with solid steel winding bars sized to the winding cone. Screwdrivers, rebar, or the wrong size bar can slip out under load.
• Correct sizing and turns. The springs must match the door's weight and height, and the number of winding turns depends on the door (in this video, 7 turns for a 7-foot door). Get either wrong and the door is unbalanced, which strains the opener and cables.
• Experience makes it look easy. You are watching an experienced technician, and parts of the footage are sped up. A first-timer working from a video is in a very different position.
