By asking about asbestos, contractors and technicians ensure that they take the necessary precautions to protect your and their health and safety during the installation process. If asbestos is present, they can develop a plan to safely work around it in accordance with local regulations. However, these extra measures will incur additional charges. If your home was built before the 1980s, there is a possibility that it contains asbestos in some form, such as in the eaves, some weatherboard, insulation, floor tiles, or roofing materials. Therefore, it's crucial to identify and safely manage any asbestos-containing materials before starting any work.
