Worn or Broken Garage Door Cables
in Huntington Beach, CA
Garage door cables are thick steel wires wrapped around drums at the top corners of the door. They carry a large share of the door's weight every time it moves. In Huntington Beach, the salt air and marine fog that roll in off the Pacific corrode the individual wire strands, and cables that look intact from a distance can be almost completely rusted through inside.
Quick Answer
Garage door cables are steel wires that work with the springs to lift and lower the door evenly. When a cable frays or snaps, one side of the door drops and the door can fall. Salt air near the Huntington Beach coast corrodes these cables fast. A technician replaces both cables at the same time so they wear evenly. Don't use the door at all once you notice a frayed or loose cable.
Telltale Signs
Warning Signs to Watch For
- One side of the door hangs noticeably lower than the other
- You can see a frayed, kinked, or loose cable hanging off the drum
- The door jerks or jumps when moving instead of traveling smoothly
- The cable has come off the drum and is coiled on the garage floor
- The door opener strains and moves slowly even though the spring looks intact
Root Causes
What Causes Worn or Broken Garage Door Cables?
Corrosion from Coastal Air
Steel cable is made of dozens of thin wire strands twisted together. Salt air penetrates between the strands and rusts them from the inside out. Homes within a few blocks of the Huntington Beach Pier see this happen in as little as three to five years on cables that were never coated or lubricated.
The Fix
Cable Replacement with Coated Cables
Both cables are replaced at the same time using galvanized or vinyl-coated steel wire, which holds up better against coastal corrosion. The drums and drum brackets are inspected and replaced if they show the same rust damage.
Cable Drum Wear or Misalignment
The cable winds around a grooved drum at the top of each side of the door. If the drum wears smooth or shifts out of position, the cable piles up unevenly, creating kinks and friction points that break individual strands. Older drums on doors installed in 1990s Huntington Beach tract homes are often worn past the point of safe use.
The Fix
Drum and Cable Replacement
The worn drum is replaced along with the cable so the new wire winds correctly. Both sides are done together so the door lifts and lowers at the same rate on each side.
