Housing in this area went up mostly between 1938 and 1983, with the median build year around 1957, and that's true across the sixteen communities we work in from Ontario out to Fredericktown. A door installed on a house from that era was engineered for the springs and openers available at the time - lighter doors, smaller motors, hardware rated for a different load than what's often hanging on the track now after decades of panel swaps or added insulation. Layer on a cold-climate winter and steel spring wire contracts, grease stiffens, and the extra force needed to lift a door on a 10-degree morning finds every weak point in twenty-year-old hardware. We see the same failure pattern across this whole belt of older housing stock: torsion springs that were fine in October and gone by January, not because the door changed, but because the metal did. It's not a coincidence that repair calls cluster hard in the first real cold snap each year.
