PCBs in Caulk and Residential Demolition
Caulk containing potentially harmful polychlorinated biphenyls (PCBs) was used in many buildings in the 1950s through the 1970s. PCBs in caulk have not been found in single-family homes. EPA has only found the chemical in caulk in large, older apartment complexes and some older buildings, such as schools.
