The root of it is the build year. With most Spanish Springs homes going up around 2001, you're dealing with first-generation production doors - single-layer steel, minimum-spec springs rated for standard cycle counts, and openers chosen to hit a builder's price point rather than a homeowner's long-term comfort. None of that was wrong for the time. It's just aged the way builder-grade materials age: slowly, then all at once.
The climate does the rest of the work. A cold-severe winter puts real stress on steel that contracts and expands daily, and on springs that were never rated with that temperature swing in mind. None of this is unique to one house - it's close to universal across the development, which is why we see the same pattern call after call in this part of the service area.
