Paradise Valley sits about 20 miles from our shop in Chandler, and most of the houses out there went up around 1985 - right at the front edge of the broader 1985-to-1993 building run that covers a big chunk of our service area. That matters because a house built in 1985 came with a different door spec than one built in 1991: section heights, track radius, and the gauge of torsion spring sized to the door's weight all shifted over those years as manufacturers changed standard panel designs. With about 4,972 households in Paradise Valley, the stock here leans toward larger lots than you'll find on a tighter subdivision street, and the doors we pull off these garages tend to run wider - double-wide openings are common, not the exception. We don't have a street-by-street survey of every build year in Paradise Valley, so we're working from the area's general 1985 median, not claiming every house matches it exactly. Still, when a torsion spring lets go on a 7-foot double door out here, the age and sizing almost always line up with hardware designed for a mid-80s build, not a newer composite door with a factory-balanced torsion system.
