Garage Door Cables Broken or Frayed
in Tulsa, OK
Lift cables are steel wire ropes that run from the bottom corners of the door up to a drum near the spring. When a cable breaks, the door drops on one side and can fall fast enough to injure someone or crush a car. Tulsa winters regularly drop below freezing, and that repeated freeze and thaw cycle corrodes cable strands from the inside out. Cables on doors built before the 1990s in older parts of town are often well past their safe working life.
Quick Answer
Lift cables are the steel wires that work with the springs to raise and lower your door safely. They fray and snap from rust, age, and the temperature stress Tulsa winters put on metal. A broken cable lets one side of the door drop fast and can cause serious injury. Stop using the door and call for service.
Telltale Signs
Warning Signs to Watch For
- One side of the door drops lower than the other when opening
- You can see frayed wire strands hanging near the bottom corner of the door
- The door opens crookedly and scrapes the frame
- A cable is lying loose on the garage floor
- The door falls faster than normal when closing
Root Causes
What Causes Garage Door Cables Broken or Frayed?
Rust and Corrosion
Oklahoma averages around 40 inches of rain per year and garages that aren't sealed well hold moisture. That moisture settles on the steel cable strands and starts them rusting. The outer strands rust first, then the inner strands, and the cable loses strength until one strand at a time starts breaking.
The Fix
Cable Replacement with Corrosion-Resistant Cable
Both cables get replaced at the same time even if only one is broken, because if one is gone the other is usually not far behind. Galvanized steel cable handles moisture better than bare steel and is the standard choice for garages in humid climates.
Cable Drum Wear and Misalignment
The drum is the cylindrical spool the cable winds around when the door opens. If the drum is worn, cracked, or has slipped out of position, the cable doesn't wind evenly. Uneven winding creates a kink in the cable, and a kinked cable frays and snaps at that spot. This is more common on doors with original hardware from the 1980s.
The Fix
Drum Replacement and Cable Re-Spooling
The damaged drum is replaced and the new cable is wound in correctly with the right amount of tension. The technician checks the other drum at the same time and tests the spring tension to make sure the door lifts evenly on both sides.
