Palm Beach's median household income runs around $175,078, well above the roughly $86,562 median across the wider service area we cover from Jupiter. That gap shows up directly in what gets installed: more insulated steel and composite doors, more custom panel finishes, fewer bare single-layer steel replacements bought purely to get something that closes.
The other driver is age. A 1971 build year means a lot of these garages have never had the opening resized or the header reinforced for a heavier insulated door - the kind that's become standard rather than optional here. When we install new, we're often not just swapping a door but correcting for decades of a lighter original door carrying light hardware that was never built for what's going in now.
Climate plays a smaller but real part - this is a mild temperate band, so we're not fighting the freeze-thaw cycles that crack old concrete door tracks in colder regions, but humidity and salt air still take a toll on any hardware that's been sitting exposed since the Nixon administration.
