Garage Door Cable Repair 101: What You Need to Know

Like an annual doctor visit, you should schedule a professional inspection of your garage door cables on an annual basis. If cables are fraying, repairs will be necessary. You can notice on visual inspection that some of the wires are broken as the cables begin to separate. If cables are fraying, they will need to be replaced.

If cables are frayed, check the balance of the garage door. Often, the springs have weakened due to the added weight of the side of the door where cables are frayed.

Inspecting Cable Loops

You’ll also want to inspect the cable loop that attaches to the bottom bracket that is mounted to the bottom panel of the garage door. The loops connect the cable, drums, and spring system to the door. They are what makes raising a hundred pound door feel as light as a carton of eggs.

Watch for Rust

Also look for any rust building up on the cables. Rusty garage door cables should be replaced due to potential weakness.

Pro tip: Spray the cables at least once a year with a lube to minimize rust.

Fair Warning

What you don’t want is for the cables to break when a door is closing or opening. This can cause the door to go sideways or off track, which could damage many of the components of your garage door.

Keep in mind that garage door cable repair should always be done by a professional. The cables are under extreme tension. If they should be suddenly released, they can cause serious bodily harm, even death. If you think your cables may need replaced, give us a call. We offer same day repairs, and even do emergency house calls.

Self Maintenance You Should Do Regularly

In addition to a professional inspection, there are a number of self maintenance repairs you should be making to your garage door at least every 3 months. Take a socket wrench and tighten down any loose parts, especially when it comes to hinges as well as the brackets that connect the rail. Make sure the track is in a perfectly vertical position. If its positioning is off, you’ll need to realign it by loosening the brackets and straightening out the track.

Finally, oil the springs, chain, and any moving parts with a garage door lubricant. Do not use WD40, which can cause the components of your garage door to prematurely rust. Instead use a silicone spray and perhaps a brush to get into the tight fitting nooks and crannies.
