STUCCO

Cracking is the formation of cracks in stucco due to shrinkage, expansion, and other movement that stresses the stucco coating.

Cracking is one of the largest complaints from homeowners with stucco homes. Cracks are unsightly and can lead to major water intrusion issues if they aren’t addressed in a timely manner. All stucco cracks are caused when the stucco releases stress placed on it by shrinkage, expansion, or other movement. Usually, stucco releases stress through a series of small cracks spread over the wall surface or at predetermined locations where control joints are placed. However, errors in stucco application can cause the stucco to store the stress until it’s forced to crack. These cracks can run deep, exposing the building materials beneath the stucco, such as housewrap, to the elements. Because these materials aren’t built to withstand prolonged exposure, water will eventually be able to penetrate them and move toward the interior of the home.
