Lift Cable Replacement for Arlington Heights Homes

The other common failure is not a break. If the door lands on something on the way down, a bin, a bike, a raised lip of slab, the cable goes slack for a second and unwraps from the drum, then rewraps over itself on the next lift. From then on the door hangs crooked and binds hard against the track.

Putting that right means releasing the spring tension, securing the door, resetting both drums level on the shaft, tensioning both cables equally and rechecking the balance. It is not something to attempt with the springs still loaded, which is why a crooked door is worth a phone call rather than an afternoon on a ladder.

Cables rarely fail on their own. With the door secured and the spring unloaded, we look at the drums for grooving and wear, the bottom brackets for movement, the springs for cycle wear, and the bottom rail of the door itself for rot or corrosion around the bracket fixings.

Bottom brackets are the part people underestimate. They sit under full spring load, which is precisely why this work belongs to someone with the right tools. If a bracket is cracked, or the fixings have pulled through a soft bottom rail, you hear about it before we reload the spring rather than afterwards.
