Start with conditions, not a product
Differential settlement around Athens often comes down to how unevenly the red clay sits over granite across the city's rolling terrain -- one side of a house can rest on shallow rock while the other sits on several feet of shifting clay, and a fix has to account for that difference.
Build a complete scope
- What was measured, and whether the movement is seasonal or one-directional
- Whether the crack follows an addition seam rather than the original structure
- How red clay holding water against the footing is being addressed
- The repair chosen, with the rejected alternatives named
- Access, restoration afterward, and the terms and limits of the warranty
Athens context
Settlement behavior differs across Athens's housing eras: historic in-town homes, student rentals, mid-century neighborhoods, and expanding suburban edges all respond differently to rolling red-clay terrain, mature trees, humid weather, and a long history of additions.
