Write it down before you call
Record where on the Carmel property the issue shows up, when it started, how it tracks with weather, and any prior repair work -- a few photos and measurements make that first call go further.
Read the local context
Carmel sits on Hamilton County's Crosby-Brookston silt loam and silty clay loam soils, developed on calcareous glacial till that expands when wet and shrinks and cracks when dry — a seasonal cycle that puts consistent pressure on foundations across the whole metro regardless of a home's age. Carmel's population grew from 6,691 in 1970 to 99,757 by the 2020 census, so most of the city's foundations were poured during that fifty-year boom, while the original Old Town core near the town's 1837 founding site carries foundations built long before modern understanding of expansive-clay soil behavior.
Ask what disappears once the work is covered
A written Carmel scope should explain the prep and verification steps that vanish from view once drywall, paint, or landscaping goes back over the repair, especially anything addressing the county's clay-heavy till.

What official local sources add
Two of these facts bear directly. Hamilton County's clay-heavy glacial till is moderately expansive and slow-draining, so moisture change against a foundation is the dominant local driver of movement — which makes drainage part of the diagnosis rather than an afterthought. And Carmel's growth from a farm town of 250 in 1874 to nearly 100,000 by 2020 means foundations here span more than a century of practice, from early masonry to modern poured walls that behave nothing alike. Structural work is reviewed by the Building Safety Office.
