Most houses in Pueblo's service area went up in the 1960s and 70s, which means a lot of original galvanized cable is still hanging on worn pulleys that have never been replaced. That cable wasn't built to last sixty years, and the drums and pulleys it runs over wear a groove over time that frays the strands from the inside, so the cable looks fine until it isn't.
Pueblo sits in a cold, severe climate band, and that kind of temperature swing is what turns galvanized cable brittle at the strands first, usually right where it wraps the drum. Cold makes the lubricant on the cable and drum stiffen up, so the door works harder on a winter morning, and a cable that's already thinning from age is the first thing to go under that added load.
From Mesa Junction to Belmont to Pueblo West, the same 1960s-70s torsion hardware shows up on call after call, and it's rarely a coincidence. Across the 12,335 households we could reach in this service area, 9,323 are owner-occupied houses with a garage door and a cable system aging on the same schedule as the house around it. If your house dates to that era and the cable's never been swapped, it's past due.
