The climate band here is cold-moderate, and that matters more for a 1975-built garage than it does for a house built in the last ten years, because older doors and openers weren't engineered with today's insulation standards or corrosion coatings. Cold snaps stiffen torsion springs and thicken the grease in older opener gearing, which is when a spring that's been fine all summer finally gives out. Cross Lanes sits about 10 miles from Charleston, and the housing stock on this side of the valley matches what we see across most of the 1960s-70s-era neighborhoods in the wider area: single-car and two-car garages with steel doors on side-mounted torsion hardware, not the newer center-mounted setups. That hardware is reliable but it's mechanical, and forty-plus years of cycling wears down the same parts in the same order almost everywhere it's installed.
