A Houston rainstorm passes, the sun comes back out, and before long most of your home's stucco looks dry again. Except for one spot.

Sometimes it's a thin hairline near a window. Other times it's a longer crack following a corner or expansion joint. The natural question is: *"Should I be worried?"*

Stucco is a strong, beautiful finish—but it’s not waterproof. It’s designed to breathe, to let moisture move through and out. When water gets in faster than it can escape, that’s when you see the telltale signs.
