Gaps at baseboards and trim
New gaps between baseboards, trim, and floors, or crown molding pulling away, can mean the structure has shifted.
What to look for
- Baseboards lifting off the floor
- Crown molding separating at corners
- Cabinets or counters pulling from the wall
- Caulk lines that keep splitting
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.
