At a median household income of $75,502 in Nederland, a cable job that comes in a few hundred dollars is worth doing on almost any door still worth having. Where the math turns is on doors from that 1966-1998 housing stock where the cable failure is really a symptom of a drum, a spring, or a track that's finished its service life. Replacing just the cable on a door with a worn-out drum groove or a bent track buys you weeks, not years.
The mild climate with occasional freeze here doesn't rust cable out the way a harsher climate would, so most of the cable failures we see in this area are wear failures, not corrosion failures. That means the cable itself usually lasted its full life. What we're really diagnosing is whether the rest of the hardware around it lasted too. On a door original to a 1973 build, the honest answer is often no, and we say so before we quote a cable-only repair that won't hold.
