Housing in this part of the service area mostly went up between 1962 and 1997, and Artondale's own median build year lands around 1989 - squarely in that window. That matters because doors from the late 1980s and early 1990s almost always came with torsion springs sized for the original steel door weight, not for the heavier insulated replacements a lot of owners have swapped in since. When someone upgrades to a heavier door and keeps the old spring, the spring cycles harder than it was built for and fails years ahead of schedule. The regional climate here is mild with occasional freeze, so we're not dealing with the wide temperature swings that fatigue metal in harsher climates - but original hardware pushing past 30 years old is still original hardware, and age alone closes the gap that a mild climate opens up. On a lot of these houses the spring has simply never been replaced since the door went in during the late 80s or 90s. That's not a defect, that's just what a 35-year-old torsion spring does eventually.
