Asbestos was commonly used in building materials for its fire-resistant properties, and it can indeed be found in older drywall or plaster walls. The presence of asbestos poses health risks, especially when the material is disturbed, releasing fibers into the air. Identifying asbestos requires professional testing, as it is not visible to the naked eye. If your home was built before the 1980s, it's wise to be cautious. Ask Improvi.ai for personalized guidance on testing and safe removal options to ensure your home remains a safe environment.
