Garner's housing stock runs 1973 through 2013, with the median build year sitting at 2001 and most of the six named areas across town dominated by that 2000s wave of construction. That matters for garage doors because builders in that window installed whatever met code and budget at closing, not what would hold up two decades later. A lot of those original doors used thin steel skins, minimal insulation, and hardware sized for the door rather than for 20-plus years of daily cycling. Pair that with a cold-moderate climate band that still swings through freeze-thaw stretches each winter, and you get steel panels that flex, torsion springs that lose temper faster than they would in a mild climate, and rollers that seize when grease thickens in the cold. None of this is dramatic. It's just time and weather working on a door that was never built to be the forever door - it was built to pass inspection on a new house. By the time a Garner homeowner notices the door is sagging at the bottom panel or the opener is straining, the door is usually past the point where patching extends its life much further.
