Stucco moisture problems arise due to improper installation, compromised vapor barriers, poor insulation, or inadequate caulking. Traditional stucco systems, lacking synthetic or acrylic components, are particularly vulnerable to moisture absorption and damage. Moisture trapped within the stucco can lead to cracking, efflorescence, mold growth, and structural issues. Addressing these problems requires professionals such as moisture inspectors, waterproofing experts, and engineers to assess the cause, determine remediation measures, and ensure proper installation and maintenance of stucco systems.
