Broken Cable Repair in Ennis, TX
The lift cable is anchored to a bracket at the bottom corner of the door that is under the full tension of the counterbalance springs. That bracket carries a factory warning label for a reason, and loosening it with the springs still wound is one of the most reliable ways to be injured by a garage door. In Ennis we release tension before touching it.

What the lift cables do and where they run
On a torsion door, a grooved drum sits at each end of the spring shaft above the opening. A steel aircraft cable winds around each drum, runs down the inside of the vertical track, and terminates at a bottom bracket bolted to the lowest corner of the door. When the springs unwind, they rotate the shaft, the drums take up cable, and the cable lifts the door. The cables carry the entire weight of the door in tension. They are not a secondary or a safety component; they are the connection between the counterbalance and the door itself, and when one fails that side of the door has nothing holding it.
The other failure mode: a cable that came off rather than broke
If a closing door lands on an obstruction, whether that is a garbage can, a joist of lumber, or a car bumper, the door stops but the drums keep turning for a moment. The cable goes slack, comes out of its groove, and then re tensions in the wrong place, often wrapping over itself or dropping between the drum and the bearing plate. Nothing is broken at that point, but the door will lift unevenly and can jam. This is also why a door that sits crooked after someone left something in the doorway needs to be looked at rather than forced back into service. Re seating that cable and re setting drum tension is the actual repair.
The bottom bracket is where people get hurt
Both bottom brackets are under the full tension of the counterbalance whenever the door is closed, because that is exactly where the cables pull. Factory labels on those brackets warn against removing them, and the warning is accurate. If the bolts are backed out while the springs are wound, the bracket departs the door under load with the cable attached. Correct sequence is to unwind the springs with winding bars first, so the cables go slack, and only then work on the bracket. This is the same reason a broken cable is not a job to improvise on a Saturday: the intact side is still fully loaded.

Please do not attempt this one yourself
A torsion spring holds several hundred pounds of stored energy even when the door is down. Releasing that energy without the correct winding bars is how people lose fingers. If a spring has snapped, leave the door closed and call us.

How a Ennis call runs
Secure the door before anything else
The door is clamped or blocked in position so it cannot drop or shift, and the opener is disconnected. On a crooked door this is the step that prevents the repair from becoming an incident.
Determine broken versus derailed
A snapped cable and a cable that came off its drum look similar from the driveway and are different repairs. We identify which happened and, if it derailed, what stopped the door in the first place, because the underlying cause matters.
Release tension and remove
Springs are unwound with winding bars so the cables go slack, then the bottom bracket end is freed and the old cable is removed from the drum. The drum, the shaft, the bearing, and the bottom fixture are inspected while they are accessible.
Install matched cables and set the drums
Cables are replaced as a pair in the correct diameter and length for the door height, seated in the drum grooves, and set to equal tension on both sides with the shaft locked so neither side takes up more than the other.
Rewind, test by hand, then by opener
Springs are wound to the correct turn count, the door is run by hand and checked for square travel at several heights, and only then is the opener reconnected, its travel and force reset, and the safety reversal tested.

Questions
Broken Cable Repair in Ennis
Should both cables be replaced or just the failed one?
Both. They were installed together, they have taken the same number of cycles, and they wear at the same two points. Replacing one leaves a new cable working against an old one of slightly different effective length, which is exactly the condition that racks the door in the track. The material cost of the second cable is small relative to the labor already being performed.
Is a broken cable dangerous?
The door itself becomes unpredictable, which is the practical danger. With one cable gone, the counterbalance is pulling on one corner, the door twists in the tracks, and it can jam partway or come off the track entirely. The other genuine hazard is the repair itself, because the bottom brackets and the intact cable are still under full spring tension until the springs are unwound.
How long does cable replacement take?
Generally one to two hours for a straightforward pair replacement, including unwinding and rewinding the springs and setting drum tension. It runs longer when the failure has bent a bottom bracket, scored a drum, or bowed a section of track, since those have to be corrected before the new cable will run true.
How often do cables need replacing?
There is no fixed interval. Cables typically outlast at least one set of springs, and many doors go a decade or more. What shortens their life is misalignment at the drum, corrosion at the bottom of the run from a wet slab, and repeated events where the door lands on an obstruction and the cable goes slack.
My cable looks fine but the door is crooked. What else could it be?
A drum that has crept on the shaft because a set screw loosened, a bottom bracket that has bent, a roller that has come out of the track on one side, or a door that has gone out of square from long running with unequal cable tension. All of them present the same way from a distance, and all are diagnosable in a few minutes on site.
