A residential garage door is comprised of two major parts: the opener and the garage door. The following steps are going to educate you on how you can handle your garage door repair on your own.
What can go wrong with your garage door?
Whether they swing up in a single piece or roll up in sections, overhead garage doors are powered by spring tension. It slides on tracks fixed to the wall, and heavy springs provides the power. Usually repairs are fairly simple. The following are useful troubleshooting suggestions:
First: Check the garage door tracks and especially the mounting brackets. Operating inside your garage with closed garage door, see if there are any crimps on the tracks, flat spots and dents. When they exist you should hammer them out with rubber mallet. You may also use a block of piece wood and hammer. When they are damaged badly, then the tracks need replacement.
Second: Use a level to check the metal tracks to ensure they are aligned properly. Horizontal ones should slightly slant down toward the rear of your garage. The vertical parts of the track, with roll-up doors, should be precisely plumb. The tracks should be at similar height on garage walls. When the tracks aren’t aligned properly, loosen but don’t remove the bolts or screws holding the mounting brackets. Tap carefully the tracks into the correct alignment. Double check your work with a level to ensure they are level. Then you tighten the bolts or screws at the brackets.
Third: You then clean the metal tracks using any strong household cleaner in order to eliminate dirt plus hardened grease. You clean thoroughly the rollers, wiping both the rollers and tracks dry.
Fourth: You check for any hardware that might be loose and tighten them if necessary. For garage doors that swing-up you should examine the spring plates to make sure that the screws their are fastened tightly. For roll-up doors its important to pay special attention to the hinges that keep the door together. If the hinges are damaged they must be replaced for a safely functioning garage door. If you find your door sagging at one side or another the culprit is mostly going to be loose hinges. If you happen to find an enlarged screw hole you need to replace them with a screw that fits better. You can also use some glue, preferably carpenter glue, in order to fill in any gaps you might find.
