Percolation Tests questions, answered by experts

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.

According to the National Cancer Institute, asbestos-related diseases can take anywhere from 10 to 40 years for symptoms to appear. The health risks increase with prolonged and heavier exposure. Risk factors also include:

  • Amount of exposure

  • Chemical makeup, size, and shape of the asbestos fibers

  • Length of time a person is exposed to asbestos

  • Genetic factors 

  • Source of exposure (direct exposure or secondhand exposure from someone directly exposed)

No, not all popcorn ceilings have asbestos, but a vast majority do. The Environmental Protection Agency (EPA) banned its use in 1973, although it still may have been used up through the early ‘90s. But, in general, homes built or remodeled before the early ‘80s likely utilized materials with asbestos. That being said, a professional test is the only way to determine for sure.

Hiring a professional for mold and toxic material testing ensures precise identification of harmful substances within a home. Professionals utilize specialized equipment and techniques, providing accurate results that inform proper removal strategies, safeguarding occupant health.

When asbestos fibers become airborne, they enter a person's respiratory system. These fibers scar and damage the lungs and often lead to serious cancers like mesothelioma. Like many dangers in the house, asbestos isn’t easy to see when it could be causing serious damage. The amount of time exposed, combined with the person’s tolerance for asbestos inhalation and the amount inhaled, will all contribute to health problems.
