Foundation Problems in Texas: What Inspectors Actually Look For
Expansive clay soils make foundation movement common across Central and North Texas. Learn the warning signs inspectors document and when to call a structural engineer.

Most Texas homes sit on slab-on-grade or pier-and-beam foundations over expansive clay. Soil shrinks in drought and swells after heavy rain, stressing concrete and framing.
Inspectors document diagonal drywall cracks, doors that no longer latch, sloping floors, and exterior brick/step cracks. They measure differential elevation when tools are available, but a home inspection is not a structural engineering evaluation.
When findings suggest active movement — especially stair-step cracks wider than 1/4 inch, significant floor slope, or separation at the roofline — buyers should consult a licensed structural engineer before closing.
Maintenance matters: maintain consistent soil moisture around the perimeter, extend downspouts away from the foundation, and avoid negative grading that pools water against the slab.
