The DIY process takes some practice, so if you don’t get it right the first time, don’t be afraid to try again. This applies to garage door repair as well so when you decide to do it yourself, here are a few tips to help you get it right.
First, you need to remove the panel from the wall by taking off the hinges on the left, right, and center parts of your door as well as the opener if your door has one. Once it’s off, inspect the whole thing and take note of any additional parts that may need to be replaced.
If there are broken, mangled, and weak pieces, add support using an angle line to strengthen them if applicable.
In this case, the panel had a broken border that introduced unnecessary flex to the whole panel and this is what needed to be fortified with an angle line and steel strip. They essentially sandwiched the weakened panel border and gave it extra rigidity. When all this is done, you put the panel back in place, lock the hinges, and test it to see how it works.
To avoid future damage, avoid closing your garage door down on things like tires and other hard objects, and also reduce the down-force acting on your garage door.
