The most common sign of asbestos is the age of your home. Asbestos was banned in drywall in 1977, though many products still contained asbestos until the 1980s. Indicators of possible asbestos in your home include:
Your home's age, if built before 1980
You have a home with vinyl flooring or millboard that was installed between 1952 and 1982
Your home has corrugated roofing
Your home has walls made from cement sheets
Your home has vermiculite insulation
Asbestos was commonly used in construction before the 1980s. While homes built after that time are unlikely to contain asbestos, there is still a possibility. Asbestos was found in materials such as flooring, drywall/joint compound, ceiling textures (like popcorn ceilings), roofing, siding, felts, HVAC systems, and more. If you're concerned about asbestos in your home, it's important to consult with an experienced asbestos professional to assess the likelihood of its presence.
