Start with conditions, not a product
Granite bedrock under Athens can sit close to the surface on one part of a lot and several feet down on another, so pier and support systems have to be designed around that unevenness rather than a single assumed depth.
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
Pier and support choices around Athens depend partly on housing type -- historic in-town homes, student rentals, mid-century houses, and new suburban construction all carry different structural histories. Rolling red-clay terrain, mature trees, humid weather, and frequent additions affect all of them differently.
