If you've lived in Texas for any amount of time, you've probably heard someone mention foundation problems. It's one of the most common concerns we hear from buyers — and for good reason. Texas soil, particularly the expansive clay found throughout the Austin and San Antonio corridor, is notoriously hard on foundations.
Why Does This Happen?
Expansive clay soil shrinks when it dries out and swells when it gets wet. In a dry Texas summer followed by heavy rain, that soil can move several inches. Foundations built on top of it move with it. Over time, this repeated movement causes the concrete slab to crack, shift, or settle unevenly.
This isn't unique to older homes either. New construction in Central Texas can show early signs of foundation movement within a few years of being built — especially if the drainage around the home isn't directing water away from the slab.
Signs That May Indicate Foundation Movement
- Doors or windows that stick, drag, or won't close properly
- Visible cracks in drywall — particularly diagonal cracks near door corners
- Gaps between the wall and ceiling or floor
- Sloping or uneven floors
- Exterior cracks in brick veneer, stucco, or the foundation itself
What We Recommend
For homes in Central Texas, we recommend adding a Foundation Measurement to your inspection. This involves taking elevation readings at multiple points around the home to document current movement levels — giving you a baseline and helping identify whether any movement is active or historic. If significant movement is noted, a structural engineer's evaluation is the appropriate next step.
The goal isn't to scare you out of buying — the vast majority of foundation issues in Texas are manageable. The goal is to make sure you know exactly what you're buying and have the information to negotiate repairs or budget accordingly.
