Western Springs households sit at a median income of $218,839, well above what drives most garage door replacement in this region, and that changes what "fails" means here. It's rarely a homeowner who can't afford a new door putting off the job - it's an original 1960-era door that still opens, so nobody's replaced it, and the springs and cables inside are now older than the warranty on anything currently sold.
With roughly 4,475 households in town, most on lots laid out the same era as the housing itself, a lot of these garages were built for a single door leaf sized to a car far smaller than what parks in it now. Swapping in a same-size replacement door without checking headroom for a modern opener bracket is the single most common local mistake we see on this kind of job - the door goes in fine, then the opener won't clear.
One honest limitation: if the jamb has shifted more than about a half-inch out of square, a new door won't fix that by itself, and framing repair is outside what a door install covers. We'll tell you when that's the case rather than force a door onto a bad opening.
