Garage door cables transfer spring force to the bottom of the door so both sides lift together. Doorcraft replaces frayed, loose, and broken cables, corrects their path at the drums and pulleys, and verifies that the door rises evenly before the opener returns to service.
Frayed strands, rust, a cable hanging beside the track, or uneven wraps on a drum require attention. Operational symptoms include one side of the door sitting lower, a door that rises crooked, a cable that goes slack during travel, or a door that will not lift after a spring failure.
A loose cable is often a symptom rather than the only failure. It can result from a broken spring, a door that went off track, impact damage, a jammed roller, or a cable that slipped at the drum. The cause must be corrected before tension is restored.
Doorcraft first stabilizes the door and identifies the cable system. We inspect both cables, the drums or pulleys, bottom brackets, springs, rollers, and track alignment. A replacement cable must follow the correct path and seat evenly; mismatched tension can make the door rack as it moves.
After installation and tension adjustment, the door is moved by hand to confirm that both sides rise together and the cables remain properly seated through the full cycle. Balance and opener operation are tested only after cable travel is consistent.
Lift cables and bottom brackets can remain under significant spring tension even when a door is stuck. Loosening a drum, winding component, or bottom bracket can release that force suddenly. Keep clear of a hanging cable and do not try to rewind it while the door is unsupported.
Tell Doorcraft which side is low, whether a spring appears broken, and whether the cable is loose, frayed, or off its drum. Leave an uneven or unsupported door in place until it can be secured safely.
