12 Warning Signs of Foundation Problems in Central Texas

Foundation movement rarely announces itself. In Central Texas it creeps in through doors, drywall, and brick as the clay beneath your slab swells and shrinks. Here are the twelve signs we get called about most — and when each is worth a free inspection.

Inside the house

Sticking doors, drywall cracks fanning from window corners, and floors that slope underfoot are the earliest indoor clues. One alone may be cosmetic; several together usually mean the slab is moving and may need steel-pier foundation repair.

Doors that stick or won’t latch
Cracks above doors & windows
Sloping or bouncy floors
Gaps at the top of walls
Nail pops in the ceiling
Cracked tile or grout lines

Outside the house

Stair-step cracks in brick, separation at the garage, and gaps opening at trim point to differential movement. These show the slab edge has dropped — read more in our guide to stair-step brick cracks.

When to get measured

If you can check more than two or three boxes, get a free elevation survey. We map the slab to ±⅛ inch so you know exactly how far it has moved — no guessing, no pressure. Homeowners across San Antonio and Austin start here.

Key takeaways
  • One sign is often cosmetic; clusters signal real movement.
  • Indoor signs usually appear before exterior cracks.
  • A free elevation survey turns guesswork into measurement.

Frequently asked

How many signs mean I need repair?
There’s no fixed number, but three or more correlated signs — especially doors plus brick cracks plus sloping floors — usually indicate active movement worth a free inspection.
Are hairline cracks always a problem?
Not always. Hairline drywall cracks can be cosmetic; cracks wider than 1/8 inch, growing, or paired with sticking doors are more concerning.
