With a median build year of 1963, most garages in Palo Alto predate the aluminum and steel sectional doors that became standard by the late 1970s. Household income here runs well above the wider area's median of $193,633 - Palo Alto's figure is $220,408 across roughly 26,054 households - which shows up in the calls we get: more requests for full door replacement with insulated steel or wood-composite panels, fewer requests to nurse a door along for one more winter. The area sits in the same mild temperate climate band as the rest of the region, so we're not fighting the freeze-thaw cycles that crack seals and warp panels elsewhere in the country. That's one thing working in these older doors' favor - the wood and hardware haven't been through decades of extreme swings, even if they're original.
