Temescal Valley is young compared to most of the area we cover. The median year built across our whole service territory is 1983, with homes going back to 1958. Out here the typical house dates closer to 2003. That changes what we find when we open a header panel.
A door installed around 2003 is old enough now that the original torsion spring has done its cycle count - most springs are rated for somewhere between 7,000 and 10,000 open-close cycles, and a door used twice a day for twenty-plus years is well into that range. But the rollers, the hinges, and the opener drive gear are often still the builder-grade parts that went in on day one, because nobody thinks about replacing a part that hasn't failed yet.
With household income here running higher than the wider service area's $83,246 median, we also see more of these original builder-grade doors get upgraded to insulated steel or composite before anything breaks - but the hardware underneath, the track and the jamb brackets, usually stays the same house to house regardless of what's bolted to it. That's the piece most owners don't think to ask about until a cable snaps.
