A door built around 1987 has had roughly four decades of cycles on its original spring, if nobody's touched it. Extension springs from that period were rated for a certain weight and a certain number of open-close cycles, and most of them are well past that count by now. That's the single biggest reason a call comes in from Ennis: a spring that's simply worn out its rated life, not a dramatic snap during a storm. Ennis sits in the same moderate heat band as the rest of the area, so we're not chasing cold-weather lubricant failures or frozen track - the wear here is mechanical fatigue, plain and simple, plus the occasional rust on original hardware that's never been replaced. With 7,711 households in Ennis, a good share of them built in that same late-80s window, this kind of failure isn't rare - it's just due.
