What Is Stucco Failure and How Does It Let Water In?

Look for cracks, especially around windows, doors, and corners. Hairline cracks may seem harmless, but they let water in over time. Also check for bulging or soft spots, which mean moisture is trapped behind the stucco.

Discoloration, efflorescence (white chalky residue), or peeling paint can signal water intrusion. If you see dark stains or a musty smell, mold may already be growing. Acting quickly can prevent more damage.

• Cracks wider than a hairline
• Bulging or bubbling sections
• Soft or spongy areas when pressed
• White mineral deposits on the surface
• Dark streaks or mold spots
• Peeling paint or discoloration

Stucco can fail due to improper installation, like missing weep screeds or poor curing. Settling of the foundation can cause stress cracks. Also, impact damage from hail or yard equipment can break the surface.

Age is another factor. Over decades, stucco naturally deteriorates. If it was applied too thin or over the wrong substrate, it may not last. Regular maintenance helps, but even well-kept stucco eventually needs attention.

If you see widespread cracking, bulging, or signs of rot, it's time to call local water damage pros. They can assess the damage and recommend the right steps. You should act quickly to prevent mold and structural issues.

The pros can also help with water extraction if water has already entered your home. They'll remove affected materials and dry the area to prevent further damage. Remember, stucco repair is one part; the water damage behind it is another.

Policies vary, and your insurer decides what is covered. Check your policy to see if stucco failure and resulting water damage are included. If you're unsure, ask your insurance company before starting repairs.
