Delray Beach sits in a mild temperate band - no hard freeze-thaw cycles that crack metal fatigue lines the way a harsh winter climate does further north. That's actually part of why spring failure here tracks age and cycle count more than season: there's no cold snap that suddenly snaps a weakened spring in January. Instead, the coil just wears down steadily, year-round, at the same rate it always has, until it's done.
What does line up with the local pattern is the housing stock itself. Across the twenty named areas that make up this service territory, homes cluster in that same 1960s-to-70s vintage, with construction continuing out to the mid-2000s. A lot of these doors have never had the spring replaced - just the opener upgraded at some point, which masks how old the actual lifting hardware is. The service area runs to 191,483 households and 69,643 owner-occupied houses, and a good chunk of those are sitting on original springs that are simply past their rated cycle count.
This pattern holds whether the house is a few miles out - Golf, three miles from Delray Beach, or Ocean Ridge at six - or further into the territory. Same building era, same failure mode, different street.
