While the springs provide the power to lift the door, the cables are the “arms” that actually hold the weight. When a cable snaps, frays, or slips off the drum, the result is immediate and chaotic: your garage door slams down on one side, leaving it hanging crookedly in the opening.
At Williamson Best Garage Doors, we fix “crooked doors” every single day. We understand that a snapped cable can appear catastrophic, but in most cases, it is a straightforward repair for our licensed technicians. Serving Montgomery County, Northern Virginia, and D.C., we arrive with heavy-duty, galvanized steel cables that are stronger than the originals. We don’t just restring the wire; we diagnose why it broke and balance your entire door to prevent it from happening again.

"My Garage Door is Crooked!" – The #1 Sign of Cable Failure
If you look at your garage door and one side is touching the floor while the other is two feet off the ground, you have a cable issue. This happens because the cables work independently on the left and right sides. If the Left Cable snaps, the Left Side of the door falls, while the Right Side (still under tension) stays up. Common Symptoms of Cable Issues:
The door is visibly uneven or "cockeyed."
You see a steel wire dangling loose or wrapped around the torsion bar like spaghetti.
Fraying cables often make a rubbing sound against the drum before they snap.
The door is stuck halfway and won't move up or down.
DANGER: Why You Must Never Cut a Tangled Cable
Even though the cable looks loose, the Torsion Spring connected to it might still be fully wound with deadly tension.
Cutting the only remaining support can cause the heavy door to crash down on you or your vehicle.
If you cut a cable under load, it can whip back at the speed of a bullet.
We have the tools to safely release the tension, untangle the mess, and reset the system without damaging your home.
Forcing a crooked door down can bend the tracks and damage the rollers, turning a $200 repair into a $1,000 track-replacement job.
Why Do Garage Door Cables Snap? (Rust, Fraying, and Age)
Cables are made of braided steel strands. Over time, they weaken due to the specific climatic conditions in the DMV.
Salt & Moisture (Rust):
In Maryland and Virginia, winter road salts carried by your car’s tires create a corrosive environment. Moisture settles at the bottom of the loop (where the cable attaches to the door), causing it to rust and snap.
Friction (Fraying):
If your pulleys or drums are worn out, the cable rubs against sharp metal edges every time the door opens. This causes individual strands to fray until the cable gives way.
Improper Spring Tension:
If the springs are too weak, the cables must carry more load than they were designed for, leading to premature failure.
The Williamson Best Upgrade: Heavy-Duty Aircraft-Grade Cables
Most builders install standard 3/32″ cables. These are fine for lightweight doors but often fail on heavier insulated or wood doors. At Williamson Best, we upgrade every cable repair to 1/8″ Aircraft-Grade Galvanized Steel Cable.
Our cables are rated to hold significantly more weight than standard wires.
The heavy galvanization protects against the humid DC summers and snowy winters.
We use a dense braid pattern that resists fraying and stretching.
Our 4-Step Cable Repair & Door Leveling Process
Fixing a cable isn’t just about stringing a new wire. It’s about Leveling and Balancing.
We use vice grips and bracing to lock the door in position so it cannot fall.
We safely unwind the torsion springs to remove all energy from the system.
We remove the old, frayed wires and install new heavy-duty cables on both sides. (We always replace both cables to ensure equal length and stretch).
This is the art. We adjust the drum tension to ensure the door sits perfectly flat on the floor. If it’s off by even half an inch, it won’t seal properly.
A crooked door often bends the vertical track. We use a hammer and dolly to straighten the track lips so the rollers glide smoothly again.

Frequently Asked Questions About Cable Repair (FAQ)
Why is my garage door hanging crooked?
This is almost always caused by a snapped or jumped cable on one side. The spring on the unbroken side pulls that side up, while the broken side falls down, creating a slant. Do not try to operate the door.
Can I replace just one cable?
No. We always replace cables in pairs. Cables stretch over time. If you pair a new (unstretched) cable with an old (stretched) one, the door will never sit level, and the old cable will likely fail soon.
How much does garage door cable repair cost?
Cable replacement is generally less expensive than spring replacement. It typically ranges from $150 to $300, depending on the door height and cable thickness. We provide a flat-rate upfront price.
Can I cut the cable if it is tangled?
NO. The cable may still be under extreme tension from the spring. Cutting it can cause serious injury. Call a professional to safely release the tension.
How long do garage door cables last?
Standard cables last 5-7 years, depending on usage and moisture exposure. Our heavy-duty aircraft cables are designed to last 10+ years with proper maintenance.
