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.

Even a single, one-time exposure to asbestos can be harmful and pose health risks. According to the EPA, any contact can increase the risk of developing asbestos-related diseases and certain types of cancer, although the likelihood of severe health issues increases with repeated or prolonged exposure.

The severity of a single exposure depends on factors like the duration, intensity, and concentration of the asbestos fibers. While a small amount is less likely to cause significant damage, a high concentration can lead to serious long-term lung damage. Individual reactions vary, and asbestos-related illnesses may not appear for 10 to 40 years after inhalation.

Given these risks, always take precautions around any material suspected to contain asbestos. Personal protective equipment (PPE) may not be completely effective. If you suspect asbestos is in your home, hire a professional for testing and removal. If you are worried about a potential exposure, consult your doctor.

Asbestos can be found in many building materials, especially if the materials were installed more than 20 years ago. Asbestos-containing materials (ACM) can include:

  • Acoustic ceiling tiles

  • Furnace insulation

  • Home appliances

  • Fire-retardant clothing

  • Cement pipe

  • Pipe insulation

  • Wall and ceiling insulation

  • Vehicle brake pads

  • Vinyl flooring

  • Sprayed acoustic ceilings

  • Stove insulation

  • Patching compounds

  • Textured paints

  • Roofing shingles

  • Siding

Regulations require certified professionals for removals and disposal in compliance with local and federal guidelines, ensuring safety and legality.

If you know your popcorn ceiling has asbestos, you should not attempt to clean it. It simply is not possible to learn how to clean asbestos safely without potentially releasing microscopic fibers into the air that could lead to severe illness in the future. Avoid disturbing or cleaning the ceiling until the asbestos removal company can get rid of the popcorn ceiling.
