There are a few different types of garage door cables, actually, depending on the type of spring system you have. If you have torsion springs in your garage, then there are torsion spring cables that loop at one end and have a crimped stop at the other end. These cables must be secured and wound in a particular way. Some garages have extension springs that run along either side of your garage door, and these springs, of course, require particular extension spring cables. The next types of cables are the safety cables that are used with extension springs, running through the center of the springs to prevent any damage or injury if the spring were to snap.
Step 1: Check the metal tracks inside the garage. Look at the mounting brackets that hold the tracks to the walls. If they're loose, tighten the bolts or screws at the brackets. Working inside the garage with the garage door closed, examine the tracks for dents, crimps, or flat spots. If there are any damaged spots, pound them out with a rubber mallet, or with a hammer and a block of scrap wood. If the tracks are badly damaged, they should be replaced.
After setting up an appointment with us, Dan showed up promptly at the agreed upon appointment time and gave us options(pros &cons of replacing vs repairing of the garage door). We decided to replace the door. Dan listened to our concerns and budget limitations very professionally and patiently. This was a first experience with garage door replacement for us. Dan actually emailed us with the estimate to replace the door immediately, very impressive!
