From 1,578 to nearly 29,000, moisture issues at very different ages
Brownsburg's population grew from just 1,578 residents in 1950 to 28,973 by the 2020 census, so a mold call here could involve a home from any decade in that seventy-year span — and each era of construction handled attic ventilation, vapor barriers, and crawlspace moisture differently, which changes where we'd expect to find a moisture source.
Creek-adjacent lots and consistent moisture exposure
Homes closest to White Lick Creek, near Brownsburg's original 1824 settlement area, sit in a naturally damper microclimate than the newer subdivisions further from the creek — worth factoring into a crawlspace or basement mold assessment regardless of the home's age.
