You spot a damp patch on the basement wall or white streaks bleeding down the facade—your brick is crying uncle. Trapped moisture doesn’t just stain; it shatters faces, dissolves mortar, breeds mold, and quietly inflates repair bills into five figures. In 2025, the Brick Industry Association and Angi’s masonry dataset tag moisture damage as the #1 failure mode for brick homes. Below, we map the destruction timeline, slap real price tags on each stage, and—crucially—expose how painting and limewashing can accelerate the nightmare if done wrong. Let’s arm you with facts so your brick breathes, not breaks.
