Read the crack before the price tag
A hairline line in drywall means something different than a stair-step crack through mortar joints. Around Champaign, cracks that open and close with the seasons usually trace back to the yellow clay subsoil swelling and shrinking beneath the black prairie topsoil, not a one-time settling event.

Why Champaign-area cracks behave this way
Champaign's neighborhoods spread outward after the Illinois Central Railroad reached the site in 1855, laid across a shallow band of dark prairie topsoil sitting on yellow clay that was historically wet enough to support a local drain-tile industry. That same clay subsoil, still shifting with the seasons, is what keeps crack repair in steady demand across Champaign-Urbana today.
