Start with conditions, not a product
Visible growth is only part of the problem. A durable plan addresses water entry, humidity, material condition, containment, and post-work verification.

Joliet-area housing-age context
Joliet's East Side Historic District carries 290 buildings, 281 of them contributing to its National Register listing, with 32 houses built between 1852 and 1873 favored near the old rail depot; Lockport's core dates to its 1837 canal-headquarters platting and 1853 incorporation, while Crest Hill and New Lenox carry a different housing-age story, built out mostly in postwar subdivision waves after their 1960 and 1946 incorporations. That range of construction eras -- pre-1873 framing, mid-century crawlspaces, and later slab-on-grade additions -- means humidity and moisture behave differently house to house, and a mold plan has to start with the age and envelope of the specific building, not a metro-wide assumption.
