A lot of Wheaton went up around 1959, well before the 1980s-90s wave that covers most of the wider area we work in. That matters because garages from that era were built narrower and shorter than what you'd find on a house from 1985 - often a single bay sized for one car, sometimes a two-car opening that's still tighter than today's standard. The doors hung on those openings used lighter torsion springs, sized for a lighter door and a smaller surface. When one of those springs breaks, you'll hear it - a bang, usually when the door's been sitting closed overnight in cold weather. The door won't lift, or it'll lift a few inches and stop, because the opener isn't built to fight a dead spring on its own. On a newer door with heavier insulated panels, the failure looks similar but the spring doing the failing is a different size entirely. That's the detail that gets missed when someone quotes a repair without knowing the house.
