With a median build year of 1957, Lakewood sits on the older end of the service area's range, which runs from 1943 up through 2012 depending on the block. Across the roughly 1.08 million households in that wider area, most of the stock dates to the 1960s and 70s - Lakewood's 1957 median puts it a notch earlier than that, closer to the original postwar wave than the later infill.
Lakewood itself has about 26,118 households, and the median income runs $116,794 - well above the service area's overall median of $96,234. That gap shows up in the work. We see more full-door replacements here relative to patch repairs, and more owners asking about insulated panels or quieter belt-drive openers rather than keeping the original steel door running another decade.
We don't have census-tract detail finer than the city-level numbers, so we can't tell you block by block where the oldest doors sit. What we can say is that a house dated to the late 1950s is a safe bet for original or near-original hardware unless a prior owner already swapped it.
