How to Prevent Cracks in Your Stucco Exterior

March 14, 2024


Stucco is a popular exterior finish for homes due to its durability, versatility, and aesthetic appeal. However, stucco is prone to cracking over time, which can detract from the appearance of your home and compromise its structural integrity. In this blog post, we will discuss how to prevent cracks in your stucco exterior, including common causes of cracks, preventive measures, and maintenance tips.

Understanding Common Causes of Stucco Cracks

Before addressing how to prevent cracks in your stucco exterior, it’s essential to understand the common causes of cracks. Some of the factors that can contribute to stucco cracks include:

1. Settlement: As a house settles over time, the foundation can shift, leading to stress on the stucco exterior and causing cracks to form.

2. Moisture: Water infiltration can weaken the stucco material, causing it to expand and contract with changes in temperature and humidity, ultimately leading to cracks.

3. Impact Damage: Physical damage, such as impact from a fallen branch or accidental bump from a ladder, can create cracks in the stucco surface.

4. Poor Installation: Improper installation of stucco, such as inadequate curing time, uneven mixing of materials, or insufficient bonding with the substrate, can result in cracks.

Preventive Measures to Avoid Stucco Cracks

1. Proper Installation: To prevent cracks in your stucco exterior, it’s essential to ensure that the stucco is properly installed by experienced professionals. This includes adequate surface preparation, correct mixing of materials, proper application techniques, and sufficient curing time.

2. Moisture Management: Proper moisture management is critical for preventing stucco cracks. Ensure that your home has adequate drainage, gutter systems, and proper sealing around windows, doors, and other openings to prevent water infiltration and damage to the stucco.

3. Regular Inspections: Conduct regular inspections of your stucco exterior to check for any signs of cracks, damage, or moisture infiltration. Address any issues promptly to prevent them from worsening and causing more significant problems.

4. Maintain Landscaping: Avoid planting trees or shrubs close to your home’s exterior as their roots can contribute to soil movement and settlement, leading to stucco cracks. Maintain proper grading and landscaping around your home to prevent moisture accumulation near the stucco.

5. Monitor Climate Conditions: Be mindful of extreme weather conditions, such as freezing temperatures, heavy rainfall, or strong winds, that can impact the stucco exterior. Take preventive measures, such as applying a protective coating or sealant, to safeguard the stucco from potential damage.

Maintenance Tips for Stucco Exterior

In addition to preventive measures, regular maintenance is essential for preserving the integrity of your stucco exterior and preventing cracks. Here are some maintenance tips to consider:

1. Clean Regularly: Clean your stucco exterior periodically to remove dirt, debris, mold, and mildew that can contribute to the deterioration of the stucco material.

2. Repair Minor Cracks: Address minor cracks in your stucco exterior promptly by filling them with a suitable stucco patching compound. This will prevent water infiltration and further damage to the stucco.

3. Seal Joints and Gaps: Seal any joints, gaps, or seams in your stucco exterior to prevent moisture penetration and reduce the risk of cracking. Use a high-quality sealant or caulk that is compatible with stucco materials.

4. Repaint as Needed: Repainting your stucco exterior can provide an additional layer of protection and enhance its appearance. Choose a high-quality exterior paint that is breathable and compatible with stucco surfaces.

5. Schedule Professional Inspections: Consider scheduling annual inspections with a stucco professional to assess the condition of your stucco exterior, identify potential issues, and recommend appropriate maintenance or repairs.


Preventing cracks in your stucco exterior requires proactive measures, proper installation, moisture management, regular inspections, and maintenance. By understanding the common causes of stucco cracks and implementing preventive measures, you can protect your home’s exterior and maintain its appearance and structural integrity for years to come. Be proactive in addressing any signs of cracks or damage in your stucco exterior to prevent them from escalating into more significant problems. Consider consulting with stucco professionals for expert advice on preventing and addressing stucco cracks effectively.
