Start with conditions, not a product
Pier depth and spacing near Rock Hill depend on reaching below the layer of clay that actively swells and shrinks, a detail a generic online estimate can't account for.
Build a complete scope
- What was measured, and whether it spanned a full wet and dry cycle
- Whether the house sits on shallow mill-era piers, block, or newer fill
- How water reaching the wall from uphill is being dealt with
- The chosen repair and what was ruled out before settling on it
- Access, finish restoration afterward, and exactly what is warranted

Because expansive clay behaves differently even across one Rock Hill lot, support work here often needs more site-specific engineering than a job on firmer, stable ground.
