Glenn Heights sits in a moderate-heat climate band, so we're not dealing with the extreme swings that crack older wood doors or that push steel panels through repeated expansion and contraction the way a harsher band would. What we do see is slower, steadier wear: lubricant drying out on rollers and hinges, torsion springs losing tension gradually instead of snapping outright, and weatherstripping that hardens over a couple of summers rather than splitting in one. With 5,734 households in Glenn Heights and a housing stock concentrated in that post-2000 window, a lot of doors in this town are hitting the same age range at close to the same time. That's not a coincidence tied to any one street - it's just what happens when a town builds out in a fairly tight period. Median household income here runs $79,739, in line with the broader service area, and most of these homes were built with two-car attached garages and standard 7-foot doors, which keeps parts fairly consistent from house to house even though we don't have a street-level map of Glenn Heights to point to.
