Most of the garage doors we get called on in Encinitas sit on houses built between 1970 and 2003, with the bulk of that stock going up in the 1980s and 90s across the nine or so pockets that make up this town. That matters because a torsion spring is rated for roughly 10,000 cycles, and a door installed when Reagan was in office has burned through that a few times over, even with light use. The original hardware on these houses - steel rollers, single-wall track, openers with worn-out logic boards - is past its design life almost everywhere we go. Encinitas sits in a mild temperate band, so we don't see the freeze-thaw cracking that wrecks doors inland or up north. What we do see is slow, steady wear: salt-carried air off the coast working into unsealed spring coils and hinge pins, and UV breaking down the seals on doors that have never been replaced. It's not dramatic. It's just decades of ordinary use catching up with hardware nobody's touched since installation.
