McDonough's housing stock runs from 1938 up through 2007, but the bulk of it - across the 17 named areas that make up this service territory - went up in the 1960s and 70s, with the median build year sitting around 1976. That matters for garage doors because a door installed on a house built in that window is likely running its second or third opener but its original track and jamb hardware. Steel brackets from that era weren't galvanized the way current parts are, and decades of a cold-moderate climate band means repeated freeze-thaw cycling on exposed lag screws and hinges. The metal doesn't snap outright - it works loose a sixteenth of an inch at a time until the door starts binding on one side. Newer builds in the service area, especially anything from the 2000s, tend to have steel jambs and sealed bearings that shrug this off. Older ones don't. If your house falls in that 1960s-70s band, the door is working against hardware that was never designed to be adjusted this many times. That's the root of most of the service calls we run - not a dramatic failure, just thirty-plus years of small shifts finally catching up with the frame.
