Garage Door Cable Replacement
The car bumper kissed the door on the way in. The bottom panel has a dent, the bracket in that corner sits crooked, and the cable on that side has jumped and gone slack, so the door reverses every time it tries to close.
Garage Door Cable Replacement
In plain words
What you get back is a door that behaves as it did when it was new. Both corners rise and fall together, the bottom seal meets the floor along its whole length, and the opener runs without straining or reversing. Because the cables were set to the same length and the springs re-tensioned to match, the door can be lifted by hand with light effort and will hold steady halfway up. You also leave with a note of the cable specification, drum type and spring turns, which makes any future service simpler, and a few habits that keep the new cables in good shape.
How the visit goesThere was a sharp crack from the garage, and when you went to look the door had dropped on one side and jammed. A length of cable lies coiled on the floor by the bottom roller.

How the visit goes
Springs and balance behind the cable
Cables only carry what the springs give them, so the springs are checked next. On a torsion system the technician looks for a gap in the coil that means a break, measures the wire and length to confirm the spring suits the door weight, and notes whether both springs on a double door match. On an extension door each spring is checked for stretch, a broken end or a missing containment cable through the middle. A weak or mismatched spring leaves one cable slack and the door heavy on one side, and if that is the story behind the cable, the spring work is explained and quoted alongside rather than left to surface later.
Fitting cables that match the door
The replacement cables are chosen for construction, diameter and length rather than taken from a general bin. Residential doors use galvanized aircraft-type wire rope, and the length depends on the door height, the drum profile and the lift type; a high-lift door or a double door has its own requirements. The swaged stop on the new cable is seated in the drum slot and the cable is wrapped in the groove in the correct direction, leaving the drum on the side that leads straight down to the bracket. At the bottom, the loop goes over the bracket pin and is secured. The other side is fitted the same way.
A clear threshold
Most cables that jump their drums do so because the door came down on something. Keep the opening clear of bins, bikes and the snow shovel, and in winter clear the ridge of packed snow and ice that forms at the threshold before running the door. If the door does meet an obstruction and stops, leave it where it is rather than pressing the button again, since a second attempt is what turns a slack cable into a tangled one. The photo eyes near the floor should be clean and aligned so they catch anything in the path; a wipe with a soft cloth each season keeps them working.

What affects the quote
Same fees day, night or weekend
1Corrosion and seized fasteners
Set screws and bracket bolts that have rusted solid take time to free or cut, and badly corroded hardware is replaced rather than reused, which shows in the parts list.
2Impact damage to track or sections
A bumper strike often bends the track, a hinge or the bottom section as well as displacing the cable. Straightening or replacing those parts is quoted as separate work.
3Springs found weak or broken
If the inspection shows a spring that is broken, stretched or wound short, replacing it is explained and priced separately from the cable work, and the two are done in one visit if you agree.
Garage Door Cable Replacement: questions
What is the difference between a lift cable and a safety cable?
A lift cable does the work: it connects the door's bottom corner to the spring system and carries the door's weight. A safety or containment cable does no lifting at all. It runs through the middle of an extension spring and is anchored at both ends so that if the spring breaks, the pieces stay put. Torsion springs sit on a shaft and do not need one.
Can I lift the door by hand while a cable is off?
Leave it. With one cable slack the door is being carried on one side only, so it is unbalanced and may bind or drop unevenly when moved. The technician arrives with clamps and a method for taking the door's weight before anything is moved, and that is the moment to lift it. Until then a stationary door is exactly what you want.
What information helps when I call?
Whether the door is sitting crooked, jammed partway or on the floor; whether you can see a cable hanging loose, frayed or wrapped around the shaft; whether there is a spring above the door or springs along the tracks; the door's rough height and whether it is a single or double; and what happened just before, such as the door coming down on something. A photo of the drum end and the bottom corner is useful.
