⚠️ Common Stucco Risks in Pennsylvania

Pennsylvania’s climate makes stucco more vulnerable to moisture problems. The most common issues include:

• Rot

• Damaged sheathing

• Structural issues

2. Improper Installation (1995–2010 Homes)

Many homes built during this period used stucco systems without proper drainage or moisture barriers.

• Soft wood

• High moisture readings

4. Expensive Remediation

Stucco repairs can range from:

• $10,000–$20,000 (minor repairs)
