On a door this age, the cable usually isn't the only part that's original. The drums, the bottom brackets, and in a lot of cases the spring are all from the same 2013-era install, and a cable repair that only swaps the cable without checking those parts is a repair that comes back. If the drum groove is worn from the original cable riding in it for over a decade, a new cable on an old drum will fray again faster than it should. We check the drum and bracket condition as part of the job, not as an upsell after the fact. The honest limitation here: if the spring is also near the end of its life, replacing the cable alone doesn't fix the door, and we'll tell you that instead of doing a cable-only job that leaves you calling again in six months.
