Kemah's housing stock centers on a median build year of 1995, which puts it noticeably newer than the wider League City service area, where the median sits around 1983. That ten-plus year gap matters more than it sounds. A house built in the mid-90s almost always shipped with a steel sectional door on an extension or torsion spring setup, paired with a chain or belt-drive opener from that generation - not the older one-piece slab doors or the heavier gauge hardware you'd find on pre-1980s construction. With 772 households in Kemah, this is a fairly small, consistent pocket of similar-era garages, which means the failures we see here tend to repeat: worn nylon rollers, opener logic boards from the 90s and early 2000s finally giving out, and torsion springs that are hitting the end of a normal 7-10 year cycle for the second or third time since the house was built.
