We don't have a posted price for cable repair, and we're not going to make one up here - what a job costs depends on whether it's a clean cable swap or a full spring-and-hardware rebuild, which is a different repair.
What we can tell you is what drives the cost difference on a Beechwood job specifically: houses built around the early 1970s in this area more often carry the older extension-spring configuration, which has more moving parts than a torsion setup - two springs, two cables, two pulleys, two bottom fixtures - instead of one centered torsion spring and a single drum on each side. More parts in the system means more that can need replacing at once, especially if one side has been quietly wearing out longer than the other.
If your opener is newer than your door, that mismatch is also worth mentioning when you call, since it changes what we bring on the truck.
