Asbestos is a naturally occurring mineral that was extensively used in building materials throughout the 20th century due to its insulating and fire-resistant properties. However, it was later discovered that exposure to asbestos fibers could lead to serious health issues, such as lung cancer, mesothelioma, and asbestosis.

Asbestos is typically found in older properties that were built before the year 2000, particularly those constructed between the 1950s and 1980s. It can be present in various building materials, including insulation, roofing, flooring, and pipes.
