What do Houston homeowners ask most?

Is foundation repair regulated in Houston?

Texas has no statewide foundation license. Use a contractor working from a licensed engineer's report, with a written transferable warranty and city permits where required.

Why does my Houston slab crack more in summer?

Clay soil shrinks as it dries, especially near large trees, so slabs lose support unevenly. Consistent moisture around the house reduces movement.

Does Houston flooding affect foundations?

Saturated soil after floods can heave clay and soften supporting soils. After major water events, watch for new cracks and sticking doors.
