Most of the housing stock in Shelby went up around 1958, part of the wider 1938-1983 build era that covers this whole service area. That means a lot of these garages still have the hardware that shipped with the house - the original track brackets, the original jamb shims, sometimes the original door itself if nobody's gotten around to swapping it. When we come out for a new install, we're not walking into a blank opening. We're walking into a frame that's been settling for six and a half decades, in a climate zone that's rated cold and severe, which is its own kind of wear on wood jambs and steel track. We take the time on site to check square, check the header, and check whether the opening itself has shifted before we hang anything new. On a house this age, that step isn't optional - it's most of the job.
