On a house built close to 2002, a failing door usually doesn't announce itself with a dramatic bang the way it might on a 1970s original setup with decades of wear. It's quieter: the opener starts straining on the way up, the door hesitates a few inches off the floor, or the remote works some days and not others. That's a spring losing tension gradually, not snapping outright - though it can still snap, and when a torsion spring that's original to a 22-year-old build finally goes, it goes without warning.
Across Grain Valley's roughly 5,898 households, most garage doors are still on their first hardware, so this pattern - slow opener strain rather than sudden failure - is the one we see most often out here compared to older sections of the service area where doors have already been through one full replacement cycle.
If your door is dragging on one side more than the other, that's usually a cable or roller issue, not the spring, and it's a cheaper fix. Worth mentioning before you assume you need a whole new door - sometimes you don't.
