Most houses out here went up around 1995, which puts a lot of garages on their original lift cables almost thirty years later. Nobody replaces a cable on a schedule - it gets swapped when it snaps, and until then it's the same galvanized strand that left the factory with the door. That's the detail that changes this job from a five-minute fix to something longer: the drum the cable winds onto is original too, and on doors this age the drum grooves are often worn enough that a new cable doesn't sit right without a matching drum. We also find the bottom brackets rusted onto the track from decades of Colorado freeze-thaw cycling, which turns a bolt-off job into a bolt-off-and-fight. If the door is a double at 16 feet wide, both cables need to come off evenly or the door racks sideways in the opening, and that's not a call we make lightly with your torsion springs still loaded.
