Depending on the amount of damage, a stucco repair professional can repair your stucco siding in four to 12 hours. If you only have a few small cracks, that repair could take as little as one to two hours to repair. In contrast, if you have an extensive fix, like foundation or chimney repair, you can expect the process to take a bit longer. Always discuss your project expectations with your stucco repair expert.

To repair damaged exterior stucco, you’ll first remove all loose and crumbling material from the damaged area. You then need to thoroughly clean the area and dampen it to ensure proper bonding. After that, you’ll apply a bonding agent to the repair area, then apply new stucco in layers, allowing for curing time between each layer. The final coat should be textured to match the surrounding stucco pattern as closely as possible. Once fully cured, the repaired area can be painted to match the rest of the wall if needed.

Stucco applied over brick can last 30 to 50 years or more when correctly applied and properly maintained. Stucco’s lifespan can be shortened by improper application, incorrectly mixed material, lack of preparation before application, and lack of maintenance. To get the most life out of your stucco siding, keep up with maintenance and repair any damage as soon as you discover it. 

Repaired stucco requires regular inspections, cleaning to prevent mold or mildew build-up, and timely minor repairs to address hairline cracks. Applying protective sealants can also enhance longevity and maintain its appearance.
