Loyola's housing stock centers on 1971, a good seven years newer than the broader Sunnyvale service area's median of 1964. That gap matters more than it sounds. Doors built around 1971 tend to run on steel torsion springs rather than the older extension-spring setups you still find on homes from the 1950s wave, and the openers that got added later in that decade were chain-drive units sized for single garages, not the wider two-car doors common in newer tracts. If your opener or spring was original to a 1971 build, it's already past the point where parts interchange cleanly with a hardware-store replacement. We see a lot of torsion spring failures and worn center bearings on doors from this exact window, and that's the repair we're set up to do correctly rather than patch. With only 1,273 households in Loyola, it's a small, consistent pocket of near-identical garages, which is useful for us - we know roughly what we're walking into before we open the truck.
