The service area overall skews newer - most of the stock here was built between 1962 and 2013, with a median around 1989. Monticello sits below that median at roughly 1979, so the doors here are, on average, a decade older than a lot of the neighborhoods we also cover. That decade matters for hardware: torsion springs and openers from the late '70s weren't built to the same cycle ratings as what goes in today, and a lot of them are still the originals.
Climate here is mild with the occasional freeze, which isn't hard on a door the way a true freeze-thaw region is, but it does mean humidity swings. Steel panels from the 1970s don't have the galvanizing or coatings that later doors got, so rust along the bottom panel and around hinge points shows up earlier here than it would on a 1995 door three streets over.
