Most of the houses in and around Garner went up between 1973 and 2013, with the median build year sitting at 2001. That's a specific problem for garage door maintenance: a door and opener installed when a subdivision was built is now old enough that the springs have cycled tens of thousands of times and the original lubricant has broken down. Six named areas across the service area are mostly 2000s stock, which means a huge share of doors here are hitting the 15-to-20-year mark at roughly the same time. Across the whole service area there are 25,222 households and 12,873 owner-occupied houses - a lot of garages hitting the same age window at once, not a handful of outliers. Garner sits in a cold-moderate climate band, so the hardware isn't just aging - it's aging through real temperature swings. Steel torsion springs stretch and contract with cold snaps, grease stiffens in winter and runs thin in summer heat, and the freeze-thaw cycle works on cable ends and hinge pins that were never serviced. None of this shows up as a sudden failure. It shows up as a door that's a little louder, a little slower, a little harder to trust - right up until a spring lets go or an opener gear strips.
