1. Repairing a broken spring
Fortunately, a whole new garage door typically isn’t necessary when you realize that a spring has broken. It’s one of the most common issues that can arise regarding your door, and a technician will usually be able to fix it without doing a complete replacement.
Garage door springs help to lift the heavy door, which means they’re constantly under tremendous tension. The springs apply a twisting force to the torsion tube while the drums at the ends of the tube act as reels, winding up the cables connected to the door. That’s why spring replacement is a task you should leave to the experts, since it can be dangerous to you and damaging to your door if attempted without the proper tools and training.
Garage door springs come in all different sizes and lengths, so the first step a trained technician will take after assessing which springs need to be replaced is to measure and make sure that the new springs will match the existing lengths and diameters. Next, your garage door repair expert will remove the broken springs and replace them with the new ones. Depending on the kind of springs installed (standard torsion springs vs. double life torsion springs), you can get between 7,000-25,000 open/close cycles out of them. In other words, spring repair shouldn’t be necessary very often.
