Sticking doors and windows: settlement signs
When a foundation shifts, door and window frames can twist out of square. If doors that used to close easily now stick, rub, or won't latch, settlement is one possible cause.
What to look for
- Doors that rub at the top corner or won't latch
- Uneven gaps above a closed door
- Windows that suddenly stick or won't lock
- Problems that change with the seasons

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.
Next steps: see house leveling, all 7 signs you need foundation repair, and what a fix might cost with the cost calculator.
