Winnetka is a small town by household count, roughly 4,268 of them, which means the garage door work here doesn't look like a big commercial route with a hundred identical openers. It looks like a few dozen houses a year, each with its own quirks, because the homes themselves are old and were built one at a time. The median year built here is 1938, which puts a lot of these garages ahead of the region's broader 1938-1994 housing band. A door built to fit a 1938 opening doesn't match modern hardware sizing, so replacement parts often need adjustment rather than a straight swap. Add the region's cold winters and steel torsion springs on doors that old have usually gone through more freeze-thaw cycles than they were designed for. That's the pattern we see: original wood or early steel panels, undersized track for the door's own weight, and springs that were never upgraded when the opener was replaced somewhere along the way. None of that is a Winnetka-specific defect - it's what happens when a town's housing predates most of the parts still sold today. We come from Skokie, about 5 miles south, and the job usually starts with figuring out what decade the hardware actually belongs to, not what the door looks like from the driveway.
