Asbestos is no longer used in new homes in most countries, including the United States, Canada, and Europe. The use of asbestos was banned in building materials in the 1970s and 1980s due to health concerns related to exposure. However, asbestos-containing materials may still be present in older homes and buildings, particularly those built before the 1980s. If you are planning to purchase or renovate an older home, it's important to have it inspected for asbestos-containing materials by a professional before beginning any work. If asbestos is found, proper abatement and removal techniques must be used to prevent exposure to harmful fibers.
