Most of Wilmington's housing went up between 1956 and 2008, with the median build year landing around 1994. That means a lot of garages still have the door that came with the house - now pushing thirty years old on the earlier end. Springs stretch out, tracks wear oval, and the steel on original panels starts to show pinholes long before anyone decides to call. You don't get the deep-freeze failures some regions see. Wilmington sits in a mild band with only occasional freeze events, so ice-locked tracks aren't the usual trigger here. What you do get is humidity working steadily on hardware year-round, plus thirty-plus years of daily cycling on springs rated for maybe 10,000 of them. By the time an owner notices the door is loud, sagging on one side, or just won't seal at the bottom anymore, the fix usually isn't a spring swap - it's a door that's past the point of patching. That's the installation call, not the repair call, and it's common across the 1980s-90s stock that makes up most of this area.
