Explored in 1673, Built Out After WWII
The Crest Hill area was first explored by Louis Joliet and Père Marquette in 1673 on their route toward the Mississippi, but its housing stock tells a much more recent story: a post-World War II building boom filled the area with new subdivisions and veterans' housing, and Crest Hill incorporated as a village on January 22, 1960 -- specifically to avoid annexation by the City of Joliet and keep the tax revenue from a developing shopping center -- with a population of 5,887 at incorporation.
One Construction Era, One Set of Vulnerabilities
Crest Hill became a city in 1969 as its population kept climbing (up 26.7% to 7,460 by 1970), and because so much of the town's housing was built inside that same compressed postwar-to-1970 window, whole blocks often share the same original crawlspace venting and vapor-barrier shortcuts -- so a moisture problem discovered in one house is a reasonable prompt to check its same-vintage neighbors.

What a Postwar-Era Envelope Needs Now
A subdivision built quickly during a single postwar boom rarely varied its foundation or ventilation details from house to house, so a Crest Hill moisture assessment should treat the construction-wave date, not just the individual home, as part of the diagnosis.
