Start with conditions, not a product
Cracks and sticking doors are clues, not diagnoses. Soil moisture, grading, drainage, framing, and foundation type need to be considered together before a repair plan is proposed.

Elgin context
Elgin's watchmaking and dairy economy left the city with housing built in distinct waves: modest worker cottages and brick flats built near the factory through the 1880s and 1890s boom years, later joined by the Victorian- and Prairie-style homes of the Spring/Douglas Historic District, built mostly from 1886 to 1920 and listed on the National Register of Historic Places in 2002. All of that housing sits on Kane County's glacial till, a compacted mix of clay, sand, gravel, and pebbles left behind by retreating ice sheets; the clay fraction in that till expands when saturated and shrinks in dry periods, a recognized driver of foundation and hardscape movement across the county and one reason foundation, crawl space, and drainage work stays in steady demand around Elgin.
