Draining moisture-retentive clay is half the job
Because DuPage County clay holds water so well, regrading and drain routing around a Naperville house can matter as much as the structural repair -- ignore that and the same clay pressure just builds back up.
What a full repair scope covers
- Existing conditions and likely cause
- Preparation and protection
- Materials, compatibility, and installation details
- Permits, testing, cleanup, and restoration
- Exclusions, warranty terms, and change-order process
