Why it happens here

Crawl Space Problem Signs and Central Texas Clay

Austin's expansive Blackland clay shrinks in dry summers and swells after rain, cycling in volume with every wet and dry season. Homes built on this clay can experience ongoing movement as the soil expands and contracts. Where that movement shows up depends on the home and foundation type.

"The most musty smells are from lack of ventilation or moisture buildup in the crawl space."
