Percolation Tests questions, answered by experts

Unfortunately, asbestos is not easily identified and can often be hidden in plain sight in your home. While it can look like fluffy fibers, tiny pieces can also appear in materials like plastic or cement, making it impossible to identify on your own properly.

Plus, since asbestos is so dangerous when disturbed, you should never root around to try and find it. This job is best for a professional who can test for the material properly.

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)

Services test for allergens, mold, VOCs, and carbon monoxide levels to ensure a healthy indoor environment.

Asbestos testing takes place in two stages—collection and lab testing. Collection can take less than 20 minutes if a professional manages to get a direct sample. If air samples are required, then the pro will set up a testing device and return to collect it. In both cases, the sample is sent to a lab and results are confirmed or denied usually within one to two days.

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
