Pre-war garages in Berwyn tend to run narrower than the 16-foot double-door openings common in newer construction, so a lot of what we install here is single doors or narrower doubles built to fit an opening that was never standardized. Track and spring setups vary more too, since these garages have usually been retrofitted at least once, sometimes twice, as owners swapped out original wood doors for steel sectional doors over the decades. You'll find torsion springs mounted where extension springs used to run, headroom that's tighter than modern code assumes, and framing that's shifted enough over 85-plus years that a stock replacement door doesn't always drop in clean. The cold winters typical of this climate band add another layer: older, less-insulated garage structures let springs and openers feel the temperature swing harder, so cold-weather spring failures show up more in this kind of housing than in a newer, tighter-built garage.
