Percolation Tests FAQs, answered by experts

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)

Depending on the size of your home, the inspection process could take a few hours or a few days. While inspecting your home, the asbestos specialist will take small sections of the potentially contaminated material. They will then send the sample to an accredited laboratory or the local health department for testing. 

The cost of asbestos testing depends on your location, the home's size, and the testing area's complexity. Plan to spend between $230 and $800 for testing. During testing and while handling potential asbestos, the specialist may wear protective gear, including gloves, overalls, appropriate footwear, and respiratory equipment.

Costs depend on test type, home size, number of testing locations, and whether follow-up testing is required.

If asbestos is found, it is crucial to consult with a professional. They will provide recommendations for appropriate abatement actions, which may include safe removal, containment, sealing, or enclosure. All actions must be planned and executed in accordance with local regulations for handling asbestos.

Professional testing is advisable to ensure safety regulations are met, and accurate results are obtained using certified methods.
