Signs Your Garage Door Cable Is Damaged
Lift cables work alongside the springs to raise and lower your door evenly on both sides. When a cable fails, it usually shows up as:
- The door hanging crooked, with one side noticeably lower than the other
- A visible frayed or fraying cable near the bottom bracket or drum
- The door suddenly feeling heavy or difficult to open, especially on one side
- A loose cable hanging away from the drum or track
- The door dropping suddenly or unevenly when opening or closing
A frayed cable that hasn’t fully snapped yet is still a warning sign worth acting on — cables rarely fail without some warning wear, and catching it before it snaps completely is safer and usually a simpler repair.
What Causes Cables to Fail
- Normal wear — cables fray gradually at points of friction, especially where they wrap around the drum
- Corrosion or rust — moisture exposure over time weakens the cable strands
- Spring-related stress— since cables and springs work together, a spring that’s failing or improperly tensioned can put extra strain on the cables
- Improper prior installation— a cable that wasn’t seated or sized correctly wears unevenly and fails sooner
What Cable Repair Involves
Because cables work under tension alongside the springs, replacing one isn’t a simple unhook-and-rehook job — the door has to be safely secured and tension released before the damaged cable can be removed. We inspect both cables and the drums during the visit, since if one cable has failed from age or wear, the other is often close behind for the same reason springs are usually replaced in pairs.
Once the new cable (or cables) are installed and properly tensioned, we run the door through a full open/close cycle to confirm both sides are lifting evenly and the door is balanced.
