Cables don't fail from age alone - they fail from cycles, moisture, and a drum or bracket that was never quite aligned right. Summertown sits in a climate band that runs cold and moderate, with real winter swings, and that kind of temperature cycling stiffens cable and hardens the lubricant in a drum bearing faster than a mild climate would. Houses here built in the early '90s are hitting thirty years on original hardware, which is right in the window where a cable that's been fraying quietly for a year finally lets go. It's not a build defect - it's just the math of thirty winters on a part that was never meant to last that long without a look.
