We don't have a fixed number to hand you here, and giving one without seeing the door would just be a guess dressed up as an answer. What drives the cost on a cable job is the door type - torsion versus extension - whether one cable or the pair needs replacing, and whether the drums or pulleys they run over are worn enough to need swapping alongside the cable. Elmhurst's median household income runs at $145,374, well above the $96,794 median across the rest of the service area, and in practice that shows up less in what people ask us to spend and more in what they choose: owners here more often ask for both cables done together rather than patching the one that broke, since the second side is the same age and under the same wear. We'll walk the door with you before we quote anything, and we'll tell you straight if a cable job is masking a bigger issue with the springs or the opener rather than talk you into work the door doesn't need.
