Percolation Tests FAQs, answered by experts

Vermiculite insulation that comes from a particular mine before 1990 is likely to contain asbestos. This is particularly true in the U.S. However, not all types of vermiculite insulation contain asbestos. Since you can't detect the presence of asbestos without special equipment, it's best to assume that the insulation contains the dangerous mineral and to either leave it alone or hire a professional to handle it.

Bathroom tiles can contain asbestos, just the same as patio tiles or kitchen tiles. Remember that asbestos was used primarily for its insulative and fire-resistant properties, both of which are desired in a house. Before we knew asbestos caused cancers and other diseases, it made a lot of sense to include it in many different building materials, including bathroom tiles.

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

Asbestos fibers can stay airborne for 48 to 72 hours, depending on the home's ventilation. Fibers can linger longer in enclosed spaces with poor airflow. Because the fibers are microscopic, they can easily remain suspended, making them difficult to detect without professional equipment.

Older textures may contain asbestos, requiring careful handling and professional inspection before work begins to ensure safety compliance.
