Common Defects
In common with the human body, defects inherent at inception or that develop from wear and tear, accident or age can present themselves throughout the life of the exterior of a building. Unlike the human body, virtually all defects can be repaired or replaced and the building can be given indefinite life.
Many exterior problems are inherent in architectural or structural design or materials that are deficient or inappropriate to local weather conditions. Other problems develop as weather wears down or infiltrates surfaces or from accidents of nature such as lightning, wind storms or rapid temperature movements. Age inevitably plays its role as materials become brittle, weak or tired from repetitive cyclical change.
As with the human body, early detection, proper response and timely maintenance can prolong a building’s life and the quality and value of its existence. The accompanying photographs depict conditions of neglect that are frequent causes of deterioration and need for major repair in Chicago buildings.
Caution: Danger Overhead
These building defects can cause bigger headaches than repair bills.
