High-Tensile Aircraft Cable Replacement & Drum Re-Spooling
Garage door lift cables transfer the rotational lifting power of the torsion springs directly to the bottom brackets of the door. Made from braided aircraft-grade galvanized steel, these cables withstand continuous tension of over 200 pounds on each side during every opening and closing cycle.
Over years of moisture exposure and friction around the cable drums, individual steel wire strands begin to fray, rust, and unravel. When a cable snaps, the door immediately lurches sideways, jamming the rollers in the tracks and leaving the door dangerously crooked. Technicians replace cables in pairs, re-spool the aluminum drums, and set balanced counterweight tension.
Overhead garage doors carry between 150 and 350 pounds of dynamic load balanced by extreme spring tension. Attempting to force a stuck door, release tensioned cables, or operate a failing motor risks severe impact injury and catastrophic gear damage.

Frequently Asked Questions About Garage Door Cable Repair
Expert guidance on common signs of failure, diagnosis steps, and professional repair standards.
A sudden sideways tilt almost always indicates that one lift cable has snapped or unspooled from its drum, dropping all counterweight load onto the opposite side.
Standard hardware wire lacks the 7x19 braid rating and certified swaged stops required for overhead door loads. Cable bottom brackets are under lethal spring tension and require professional handling.
Water and road salt dripping from vehicles accumulate near the bottom bracket, creating electrolytic corrosion that weakens individual steel strands over time.
Cables jump drum grooves when the door hits an obstruction during closing, slackening the cable, or when worn track rollers tilt the door enough to misalign drum entry angles.
Yes. Replacing only one cable leads to uneven tension because new steel cables have different elasticity than aged ones, causing the door to pull crookedly.
Warning signs include visible wire whiskers fraying near the bottom loop, rust discoloration, kinking along the length, or a cable that appears loose when the door is closed.
Aircraft-grade galvanized steel cables typically last between 8 and 12 years under standard residential cycling and regular lubrication.
Disconnect opener power, clear vehicles and pets away from the door opening, and do not attempt to pry the low side level. Call for emergency dispatch immediately.
