Wall cracks: when to get a foundation inspection
A hairline crack can be harmless drywall shrinkage. Cracks that grow, run diagonally from door or window corners, or reappear after patching are worth a professional look.
What to look for
- Diagonal cracks from the corners of doors and windows
- Cracks wider at one end than the other
- Cracks that come back after you patch and paint
- Cracks where walls meet the ceiling

Why San Antonio homes show it
Most Bexar County soil is Blackland Prairie clay that expands when wet and shrinks when dry. That shrink-swell is the primary reason for foundation issues in the county (Texas Master Naturalist, Alamo Area Chapter).
Symptoms alone don't diagnose a foundation. It may be cosmetic or a drainage fix. A professional inspection tells you which.
