We don't have a flat number to quote here, because cable repair cost depends on whether one cable or both need replacing, whether the drums or pulleys are damaged, and whether the spring tension needs resetting at the same time. A straightforward two-cable replacement on a standard torsion setup costs less than a job where the drum is also gouged or the bottom panel took damage from an uneven drop. What we can tell you is that we price the job after we see it on-site, not over the phone, because guessing on cable work usually means either overcharging or underquoting once we're under the door. If a door's cable has failed more than once in a short span, we'll tell you if that's a tensioning issue worth fixing outright rather than paying for cables again in a year.
