DeSoto's building stock lines up with the broader pattern across this part of the service area, where housing and light commercial construction runs from 1953 through 2014 with a median year around 1990 - and DeSoto's own median sits close behind that at 1993. That means most of the commercial doors we work on out here aren't decades-old outliers, but they are old enough that original hardware is at or past its rated service life.
The climate band here is moderate heat, not the extreme swings you'd get further west, so we don't see the spring failures driven by big daily temperature swings the way some regions do. What we do see is steady, cycle-driven wear - consistent enough that a door installed in the early 1990s and never serviced is due, not overdue by some dramatic margin, just due.
With median household income in the low-to-mid $80,000s across the wider service area, we tend to get called in before a full failure rather than after - owners fixing a noisy drum instead of waiting for a snapped cable.
