When Should You Get Garage Door Cable Repair?

Nowadays, garage doors can weigh up to 400 pounds! That is why it is quite difficult to move when anything is wrong. As a result, a garage door system is more than the door and the rails it runs. The system consists of extension springs, large torsion springs, cable drums, and garage door cables.

When one of these components fails to function unexpectedly, the door may become immobile or tumbling down! The door will remain inoperable until the damaged component is repaired or replaced. While some repairs are straightforward, others require the expertise of an experienced specialist.

Each component has a distinct purpose. The tracks keep the door aligned; the springs assist in lifting the door’s weight, and the garage door opener effortlessly elevates the entire structure with a button push. These cables and drums provide a failsafe if the springs become damaged.

How Can You Determine Whether Your Garage Door Cable is Faulty?

Many factors can cause your garage door opener to malfunction. However, if you see any of these issues, it may signify that something is amiss with the wires.

The door is not properly opening.

If your garage door opens unevenly, examine the motor and springs first. The cable may be damaged if the motor operates normally and the springs are in place.

Unbalanced entrance

In the case of a sagging garage door, it is most likely due to frayed cables. Fix this problem by readjusting the cables. Frayed cables can occasionally also result in an uneven garage door.

The door is completely inoperable.

A broken garage door cable drum can result in the garage door no longer functioning.

Certain garage doors additionally provide safety measures. As a result, when the cable is severed, the door comes to a halt to avoid harm.

The door is shutting far too quickly.

Your garage door could be slamming shut due to a damaged or faulty cable.

Cable dangling

Typically, when the garage door cable snaps, it hangs loose beside the garage door.

What Causes Garage Door Cables to Detach?

To repair a garage door cable yourself, you must first determine the source of the problem. Most garage door cable issues include the following:

The cable has snapped.

Over time, garage door springs can deteriorate and eventually snap. If this occurs, you will notice it by inspecting the cable.

The cable detaches from the drum.

Numerous factors can contribute to the cable not being wound properly around the drum or slipping off. To begin, verify that the diameter and length of the wires are appropriate for your garage door. Additionally, verify the drum’s size. Typically, tall doors necessitate the use of huge drums. Occasionally, cable problems emerge due to springs that lack tension. The wires can slip off the drums when the springs are overly tight.

Cables have the potential to become unraveled.

When the wires on your garage door unwound, you must replace them.

Frayed cables

By looking at the appearance of your garage door wires, you may readily determine if they are frayed. And you will need to replace them right away.

Is It Possible to Prevent a Lifting Cable from Breaking?

While it is impossible to prevent a wire from breaking, routine maintenance will add years to its life. Cables typically fail due to age or damage. The most effective technique to extend the life of your system is to keep everything balanced and oiled. When the door is in operation, numerous components move, and each one might cause friction if not operated properly and lubricated.

A common indicator that your system needs servicing when the door is moving is a squeak. Although the cable is lubricated, additional components (such as the pulley, springs, and opener) will require lubrication. Unwanted noise can result from sticky rollers, unlubricated springs, and openers. Generally, a good injection of silicone or graphite will eliminate undesirable noises.

What Information Do You Require Before Repairing Your Garage Door Cables?

Before repairing your garage door cable, it’s critical to understand its function in your garage door system. A garage door cable is a galvanized twisted wire connected to the torsion spring on one end. An end of the cable attaches to the frame of the garage door. In conjunction with the spring, this cable ensures the door opens smoothly. Additionally, it alleviates tension on the springs, extending their life.

Another critical function of the cable is to keep the springs in place if they break. Additionally, if the springs fail, the garage door may crash shut. And this can result in significant injury to you or your vehicle. However, if your garage door cable is in good condition, it will keep the door from slamming shut even if the springs fail. The garage door cables function links the spring system to the door.

There are two basic garage door spring systems: torsion spring and extension spring.

Torsion systems utilize springs mounted on the wall above the door, connected by a metal bar, and one cable on each side. Each side of an extension system has two cables. One traverses the spring while the other raises the door. This cable utilizes a pulley to convey the opener’s lifting force to the door. Replacement cables are often readily available, depending on the size and style of your door. You’ll need an exact replacement cable, so conduct an online search if you can’t locate one locally. Do not attempt to utilize a cable not specifically designed for your system.

How to Repair a Garage Door Cable On Your Own?

Here are a few brief guidelines to assist you in self-repairing your garage door wires.

Garage door spring replacement

To begin, open and secure the door. To manually open the door, pull the emergency release handle. Doing so will bring the door opener to a halt. Secure the door using vice grips underneath the bottom roller. Now, unwind the springs to release the strain. To do so, you’ll need to unscrew the springs’ screws. To avoid safety hazards, always insert the winding bars fully. Additionally, determine whether your garage door has two springs. If this is the case, repeat these instructions for the other spring.

Loosen the fasteners on the drum with a wrench and disconnect the cable.

Following that, disconnect the cable from the bottom bracket. Remove the bracket screw with a socket wrench.

After completely removing the old cable, you can begin installing the new one. Secure the replacement cable to the bottom bracket and wind it around the drum. Remember to tighten the cable by rotating the drum anticlockwise. Finally, screw it in place.

If only one cable breaks, it is better to replace both. In this manner, you can confirm that both the cables are the same. Finally, using winding bars raises the tension on the springs. Release the emergency latch down to reengage the door.

Adjusting slack garage door cables

You will require the following tools:

  1. C-clamps
  2. Locking pliers

To begin, use the automatic control to close the garage door completely. If you see a little space between the garage door and the ground, this results from the garage door’s loose wires.

Pull down the red wire to disengage the door- this method will disconnect the door’s drive chain and place it in manual mode.

Please open the door manually with your hands and secure it using clamps. Certain garage doors include clamps for the track. Alternatively, if your door does not already have clamps, you can use c-clamps. Additionally, some garage doors feature a metal lock that slides into the track to secure the door in place as you open it.

If the cable has fully detached from the pulley, wrap it around it with your hands. While wrapping the cable, ensure that it is secure. Bear in mind that the springs will exert tension on the cable, which will become even tighter once the door returns to its original position.

Adjust the cable bracket first if your garage door cable is slack. If the wire remains slack, you’ll need to loosen the bracket that secures it to the hook. Pliers will come in handy for this task. Pull the cable through the bracket and secure it. Finally, reconnect the cord to the frame.

Close the door and pull the red rope to reengage the door opener.

Is Garage Door Cable Replacement Necessary? Is It Safe to Do It Yourself and How Long Does It Take?

Depending on the condition of your garage door, repairs may take three to five hours. It is extremely dangerous to repair a garage door cable since incorrect steps can lead to injury. Tightening loose cables is simple and does not pose the same risk as replacing them. Additionally, extension springs are less difficult to replace than torsion spring cables. The reason is that torsion springs are extremely tense. Thus, the spring may fly across the garage if something goes wrong, resulting in serious injury. Additionally, there is a chance of falling garage doors, whether you’re repairing extension spring cables or torsion spring cables. Therefore, if you cannot repair the garage door cable, contact a professional service.

How to Properly Maintain The Cables on Your Garage Door?

  1. Always seek professional assistance with garage door cable repair.
  2. Do not attempt to fix garage door cables on your own.
  3. Ascertain that your garage door cables are in good condition.
  4. Inspect your garage door wires for wear and tear regularly.
  5. When your garage door cables begin to show corrosion or wear and tear, it is time to replace them.

If you follow these suggestions, it may assist in maintaining the proper operation of your garage door cables and avoid the need for repairs. However, if your cables get broken or worn out, contact a garage door repair company immediately to have them replaced and your door restored to its previous state.

What Are The Costs of Fixing a Garage Door Cable?

The cost of repairing a garage door cable varies according to the door’s make and model and the extent of the damage. Garage doors fall into two types: sectional and panel. Repairing a sectional door is more expensive than repairing a panel door. Additionally, the cost depends on the degree of damage to the cable. If it is more than 10% damaged, it will be costly to repair since you may need to replace the entire cable or only a few strands of wire. If a spring breaks and exposes a wire, the repair cost will be approximately $40–60 US dollars. If the cable has snapped to the extent that one strand hangs loose, you will need to purchase a replacement cable, which will cost approximately $60–80 USD per strand. When replacing the cable from end to end, the cost may range between $200 and $400.


Cable repair on a garage door is essential maintenance work that should be completed by a trained and experienced professional. Garage door cables are a vital component for the door to function smoothly. If your wires become broken or worn out, it might result in an imbalanced and difficult-to-operate garage door. A competent garage cable repair expert will be able to replace damaged or worn-out cables quickly and easily, restoring your door to its original state.

If you require garage door cable repair, contact a reliable professional who possesses the essential experience and expertise to complete the task correctly.
