Whether it is roll-up or roll-up garage doors, they rely on the elasticity of springs. Powered by one or more heavy-duty springs, the doors move along metal tracks in the walls of the garage. In most cases, if the door does not work smoothly, the repair is fairly simple. Here are some practical maintenance tips:
Step 1: Check the metal track inside the garage. Look at the mounting brackets that fasten the track to the wall. If the support is loose, tighten the bolt or screw. Close the garage door and check inside the garage for dents, bends, or flattening of the track. If there is any damage, use a rubber mallet or a piece of scrap wood resting on a hammer to strike the area. If the track is badly damaged, you must replace it.
Step 2: Check the track with a level to make sure the track is on the same level. The horizontal track should be slightly inclined towards the rear of the garage, and if it is a rolling door, the longitudinal part of the track should be precisely vertical. On the wall of the garage, the two tracks must be at the same height. If the tracks are not aligned correctly, loosen the screws or bolts holding the brackets in place, but do not remove them, and then carefully tap the tracks to move them into place. Recheck the tracks with a level to make sure they are in the correct position; Then tighten the screws or bolts on the mounting bracket.
