Median year built here is 1967, which puts Colonial Park squarely in the stretch of housing stock that went up with steel doors, chain-drive openers, and torsion springs rated for a lighter door than what often replaced them later. Thirty-plus winters of cold-climate swings do the rest: steel panels rust from the bottom rail up where snowmelt sits, and spring steel fatigues faster in sustained cold than the warranty sticker ever accounted for.
The failure pattern we see tracks the build year. A 1967 house with its original torsion spring is well past the cycle count that spring was rated for, even if nobody's touched it. When it finally lets go, it usually takes a cable or a bent track with it because the door was already out of balance for months before anyone noticed the opener straining.
