Before delving into asbestos removal costs, it's important to understand what asbestos is and why it's harmful. Asbestos is a naturally occurring mineral that has been used for centuries due to its heat-resistant and insulating properties. It can be found in a number of building materials, including roof tiles, ceiling tiles, insulation, and pipes. However, prolonged exposure to asbestos fibers can lead to serious health problems, including lung cancer, asbestosis, and mesothelioma.
