Read the local context
That watchmaking boom left Elgin with a housing stock built in distinct waves: modest cottages and brick flats built alongside more ornate homes for factory owners and managers during the Elgin National Watch Company's 1880s–90s growth years, concentrated today in the Elgin Historic District and the Spring/Douglas Historic District, where most homes went up between 1886 and 1920 and were added to the National Register of Historic Places in 2002. Underneath nearly all of it sits Kane County's glacial till — a compacted mix of clay, sand, gravel, and pebbles left by receding ice sheets — whose clay fraction expands when saturated and shrinks when dry, a recognized driver of foundation movement across the county, while the Fox River itself has produced federally declared flood disasters in 1996 and again in April 2013, prompting the City of Elgin to actively monitor river height and track bank erosion and property flooding along its banks.
Ask what will be hidden
Roof runoff, grading, hydrostatic pressure, wall cracks, floor joints, drainage, and interior humidity can create similar symptoms with very different solutions. The written scope should explain the preparation and verification that will no longer be visible at completion.

What official local sources add
Kane County sits on glacial till left behind by receding ice sheets — a compacted mix of clay, sand, gravel, and pebbles whose clay fraction expands when saturated and shrinks when dry, a recognized driver of foundation and hardscape movement across the county. The Fox River watershed running through Elgin has produced repeated flood events, including a federally declared disaster in 1996 and further Fox River-area flooding in April 2013, and the City of Elgin actively monitors river height and has recorded bank erosion and property flooding along the river during high-water events. Because water table and drainage exposure vary block by block along the river, parcel-specific flood status and drainage conditions should be checked before foundation, grading, or exterior work begins.
