Lakewood's housing stock centers on a median year built of 1957, and the commercial strips and light-industrial buildings that went up alongside those postwar tracts are from the same era. A door that old was built for a lighter-duty rolling curtain or an early sectional design, neither engineered for the cycle counts a modern loading bay sees.
The service area as a whole runs mostly 1960s-70s stock across its named communities, with houses generally dating from 1938 to 2005. Lakewood sits on the older end of that range, which means more of the original hardware is still in place - heavier steel, fewer safety sensors, springs sized for a lighter door than what's often been swapped in since.
The climate here is mild temperate, so we're not fighting the rust and seized bearings you'd see in a wetter or colder region. What ages these doors is mostly cycle count and original hardware outliving its design life, not weather. A 1957-era rolling door that's seen decades of daily use is going to show it in the springs and the curtain edge before it shows it anywhere else.
