Crack Control: A Homeowner’s Guide to Stucco Crack Repairs

Identify Cracks Early: Regularly inspect your stucco for any signs of cracking. Even small hairline cracks can allow moisture to seep in over time. Pay close attention to shaded areas, corners, and spots near windows or doors.

Assess the Severity: Not all cracks are the same. Hairline cracks are often superficial, but larger or spreading cracks may indicate deeper structural problems. Proper assessment helps you choose the right repair method.

Clean Before Repairing: Use a brush or hose to clean the cracked area. Remove all dust, dirt, and debris so that the patching material can adhere properly and last longer.

Use the Right Repair Materials: For small cracks, an elastomeric sealant is ideal as it stays flexible through temperature changes. Larger cracks may need a stucco patching compound or even professional attention.

Match Texture and Color: Blend the repaired area with the existing stucco by matching both texture and color. Use a sponge, trowel, or texture roller to mimic the original finish. Paint over the patch if needed.

Don’t Ignore Reoccurring Cracks: If cracks keep coming back in the same spot, it might be due to foundation movement or poor past repairs. It’s best to have a professional evaluate and fix persistent issues.

Consult a Professional for Major Damage: When in doubt, especially with wide or deep cracks, get help from a stucco contractor. They can properly assess and repair the damage to prevent water intrusion and structural issues.
