The most common exterior finish in the western United States is stucco. Construction defects in stucco wall systems can devalue a property by undermining its structural integrity and esthetic qualities. In the worst case, they can endanger health and create unsafe conditions if left unresolved.
Construction defects that affect stucco include siding that is too thin, has excessive cracking, is discolored or stained, or is missing vapor barriers. Other construction defects found in stucco walls include:
- Stucco condition that allows water intrusion
- Inadequate attachment of the lath
- Insufficient embedment of the lath into the stucco
- Corroded metal lath
- Unsealed holes, rips, and tears in the building paper
- Buried or missing weep screeds
- Brick and stone wainscots improperly installed
These problems can result in a weakened wall structure and other deficiencies.
