Garage Door Cable Replacement in Mordolphin
Your older door has springs along the tracks, and one cable has slipped off its pulley and dangles slack. The door lifts crooked and needs a shoulder to close, when it used to glide.
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 goesThe door went up as usual this morning, then stopped a third of the way with one corner higher than the other. It is wedged at an angle in the opening, the opener is humming, and nothing you press will move it.

How the visit goes
Torsion or extension, and which lift
The technician identifies the counterbalance before choosing parts. A shaft with drums above the header means a torsion system; springs stretched beside the horizontal tracks with pulleys mean extension. Then the lift type: standard lift on most attached garages, low headroom hardware where the ceiling is tight, and high lift where the door climbs well above the opening before turning. Each uses a different drum profile and a different cable length, and a double door of the same height may need a heavier cable than a single. Reading these details correctly is what makes the replacement cable wind evenly on the drum instead of overlapping.
Removing the old cables
Each drum's set screws are backed off so the drum spins freely on the shaft, and the old cable is unwound from its groove and the stop slipped out of its slot. At the floor, the loop is lifted off the bottom bracket pin, or the clevis pin and cotter pin are withdrawn where the door uses them. The old cable is kept for a moment to measure against its replacement and to show you the wear that caused the call. On an extension door the cable comes off its pulleys and the adjusting clip at the track hanger. Both sides are stripped before anything new goes on.
Cables and springs on the same clock
Cables and springs age together, and your new cables now have a head start on the springs that remain. If the springs were assessed and left in place, you have a rough idea of the cycles they have left, and the sensible plan is to have them changed as a pair before they break, at which point the cables are checked again and simply re-tensioned. A door that starts to feel heavy, a spring that has gone quiet and then begins to creak, or a gap appearing in the coil are the signs to act on. Handled this way, the counterbalance is renewed in planned visits rather than on a difficult morning.

What affects the quote
Same fees day, night or weekend
1How the door is sitting
A door resting closed is simpler than one wedged crooked in the opening or off its track, which has to be supported and straightened before the cables can be handled.
2One cable or the pair
Cables are normally renewed together, and the quote reflects two cables and the work of setting both sides level. Where one side was recently replaced, that is discussed on site.
3Oversized, commercial or high-lift doors
Doors taller or wider than a standard residential opening, or fitted with high-lift hardware, use heavier cables and drums and take longer to set up, which the quote reflects.
Garage Door Cable Replacement: questions
How long do lift cables usually last?
Cables tend to live about as long as the springs they work with, often ten years or more on a door used a few times a day, and less on a door that sees heavy use or a wet, salty floor every winter. Rather than a calendar, watch the condition: fraying, rust near the loop or a slack side are the signs the set is due.
What happens during the visit?
The opener is disconnected and the door clamped. The technician identifies the counterbalance type, inspects both cables, the drums, brackets, rollers, track and springs, and explains what is found. The springs are unloaded, the old cables removed, new ones fitted and set so the door is level, and the springs wound back. The door is then balanced by hand, the opener reconnected and its safety features tested while you watch.
Why do cables rust faster than the rest of the door hardware?
Because of where they live. The bottom loop of each cable sits at floor level in the corner of the garage, exactly where slush and road salt drip off the car and pool through the winter. Salt water works into the strands and rusts the cable from inside, so it looks thin and brown near the bracket while the upper run still looks new. Keeping that corner clear and lightly lubricated slows it considerably.
