Gardner's housing is newer than a lot of what we service - most of it went up after Kansas adopted its current cold-climate building code, which means tighter garage envelopes and openers installed to spec rather than retrofitted. That's good news structurally, but it also means these doors see real temperature swings on hardware that's plastic-heavier than the steel-gear openers from the 1980s. Cold mornings make drive gears brittle, and a gear that's already hairline-cracked from age will finally let go on the first hard freeze of the season. With 8,175 households in Gardner and most on that same build timeline, we see the same failure cluster through a cold stretch - not a flood of calls, but a steady run of the same drive-gear and sensor fix across houses that were all framed within a few years of each other.
