Those two cables are attached to the bottom garage door hinges. That allows them to pull the door open and close. Often, the areas where the cable connects to the hinge gets rusty. From there, it’s just a matter of time until the hinge breaks or the cable snaps.

You should avoid this situation at all costs for a couple of reasons. First, if your one cable snaps, the whole door can get off tracks. It can cause extensive damage to your vehicles or, even worse, you or your family members. In addition to that, repairing such damage isn’t cheap and may require installing a brand new door.

It’s not going to be a simple garage door cable repair anymore. Dissembling a damaged overhead door and installing a new one can cost over 1000$ depending on the door’s type and manufacturer. Taking preventive actions, however, can eliminate this problem.

Even if the cable just snapped and your door is intact, it is still a pretty lengthy process to get your garage door cable repair done. See, you need to unwind the springs first. It will ensure a safe working environment for a technician and allow for installing new cables. If your garage door springs are worn out as well, it might be a good idea to replace those as well.

Inspect your cables and bottom hinges at least every quarter. If you see any signs of moisture or rust build-up, you should take care of that ASAP. Usually, we do not recommend using WD-40 for your garage door, but in this case, you can apply it to your bottom hinges and cable connections. You can also visit your local hardware store and ask for a good anti-corrosive substance you can use.
