Housing in the Bradenton service area was mostly built between 1964 and 2012, with the typical house dating to around 1976, and across the 32 named areas we cover it's overwhelmingly that same 1960s-70s wave of construction. A door installed on a house built in the mid-70s is very often still running on the track and hardware that came with the house - steel track that's fifty years old, brackets that have been tightened and re-tightened by whoever owned the place before, rollers that were never upgraded to nylon. That's the hardware that lets go first.
The climate here is mild temperate - we're not fighting hard freezes that crack metal or snow load that bends a track overnight - but the humidity swings near the Gulf still work on steel over decades, and salt air corrodes fasteners faster than it would inland. Combine fifty-year-old track hardware with that slow corrosion and a bracket that's been loose for months finally gives, usually on the day someone backs out too fast or the door gets a stiff jolt. It's rarely one dramatic event - it's decades of original hardware finally running out of room to flex.
