Garage door spring replacement in Harpenden: common questions
How do I know a spring has broken?
You may hear a loud bang from the garage, then find the door heavy, opening only a little, or the motor straining. A broken torsion spring shows a visible gap in the coil. A failed tension spring may hang loose or be held by its safety device.
Why is spring work not DIY?
Springs store a lot of energy. Winding a torsion spring needs proper winding bars, and releasing tension carelessly can cause serious injury or let the door fall. Please do not attempt it.
