Housing in this area was mostly built between 1938 and 2005, with the median landing around 1965, and the bulk of it is 1960s and 70s stock. That matters for garage doors specifically: doors installed when these houses were built are now 50-plus years old, and even doors replaced once since then are often 20 to 30 years into a design life that wasn't built for today's insulation standards or today's heavier openers.
Old Bridge sits in a cold-climate band with severe winter conditions, and older single-layer steel doors were never built with the thermal break or insulation thickness that current codes call for. Every freeze-thaw cycle works on the seams, the bottom seal, and the panel joints a little more. On a house from that 1960s-70s wave, you're often looking at a door that's outlasted its hardware, its seal, and its insulation value all at the same time - which is a different problem than a single broken spring, and it's why patch repairs on these older doors tend to buy you months, not years.
