Garage Door Cable Replacement: comparing quotes

Yes, as a rule. The two cables were fitted together, have flexed around their drums the same number of times and have sat in the same slush, so the survivor is close to the end of its life. A new cable beside a stretched one also makes it harder to set the door level. Two matched cables give an even lift and one visit instead of two.

Oversized, 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.

Torsion or extension system

A torsion door with drums and an extension door with pulleys are different jobs with different parts, and the counterbalance type is the first thing that shapes the quote.

Whether a matching part has to be special-ordered

Most drums, brackets and cable sizes are common stock, but an older or uncommon door sometimes needs a part matched to its exact dimensions. When that happens the technician identifies it on the first visit and arranges the part before the return trip.
