Courts, construction experts, and lawyers typically categorize construction defects in one of four broad categories: design deficiencies/defects, material deficiencies/defects, construction deficiencies/defects, or subsurface deficiencies/defects.
Material defects are frequently the target of construction defect lawsuits. The use of inferior building materials or materials not properly designed for the structure in question can cause significant problems. Among other things, windows can leak or fail to function adequately, even when properly installed. If building materials are not manufactured properly it can result in rapid deterioration and failure to function properly for the intended use.
