How to tighten garage door extension springs.

Side mounted springs are long heavy springs mounted on each side of the upper garage door track. With an extension spring door the goal is to take all the tension off the door before you even think about touching a spring you can do this by opening the door all the way and propping it up with a ladder. You need to increase the tension in case the door can be lifted only with difficulty or if it closes faster than it should. To adjust your garage door s side mounted springs first open your door fully and secure it in place with a c clamp below the bottom roller.

Brace door before adjusting extension springs. This tension makes it easier to lift the garage door from its closed position. See below to make sure the door is secured before you work on it. A garage door that is not attached to the springs can fall and cause injury.

The way you adjust the springs depends on the type of issue. For extension springs this is in the up position. Open it just as wide as you can without hitting the garage door opener s stop bolt and place a clamp on the track on both sides to keep the door in. Once your garage door is secured remove the spring hook from the track hanger which will allow you to move the hook and adjust the spring s tension.
