How Clay Soil Moves a Houston Foundation

What To Do When You Spot Multiple Signs

Frequently Asked Questions

Is foundation movement in Houston normal?
Some degree of seasonal movement is expected in all Houston-area homes built on expansive clay soil. The question is whether the movement is within normal tolerances (less than 1 inch differential per FEMA guidelines) or whether it's progressive and causing structural damage.
Can I fix foundation issues myself?
No. Foundation work in Texas requires a licensed structural engineer's assessment and a contractor with the equipment to install piers or perform mudjacking. DIY foundation work is unsafe and almost always voids homeowner's insurance coverage.
