Natural stucco is applied in layers over wire mesh. Joints in the wall let it expand and contract with the weather, and weep screeds help moisture escape. It’s a great insulator, especially against heat.
Impacts or structural movement can damage stucco. Termites are a concern. While they don’t eat stucco, they can burrow into it and enter your home undetected.

Step 1: Look for cracks or holes. Check around windows, doors, and corners, as these are common problem areas. Repair any openings to prevent damage to the stucco or the structure beneath it.
Step 2: If your home has a weep screed or weep holes, clear away dirt, debris, or vegetation so water can drain. If it doesn’t, just keep an eye out for water stains.
Step 3: Check for discoloration or staining. Black or green stains could be mold or mildew. Other discoloration could indicate a moisture problem. Windows and doors are common problem points.
Step 4: Remove anything growing on your stucco. Moss, lichen, mold, and vines can damage it. Make sure shrubs are trimmed back at least 6 inches from your walls.
Step 5: Check yearly for signs of wood-eating insects, such as sawdust and small holes. If you’re concerned, call an expert to do a professional inspection.
