San Antonio sits on expansive clay soil (called 'black gumbo') that swells when wet and shrinks when dry. This seasonal movement causes foundation settling, cracked walls, and sticking doors. Consistent watering around the foundation perimeter during dry months significantly reduces movement.

How do I prepare my home for a San Antonio ice storm?

While rare, San Antonio ice storms (like the 2021 freeze) can cause significant pipe damage. Insulate exterior pipes, know where your water shutoff is, and consider a smart thermostat that alerts you if indoor temps drop dangerously low.
