Percolation Tests questions, answered by experts

Homes built before the 1990s may contain asbestos, but the only way to be sure is to have your home tested. Hire an asbestos testing and removal service to determine whether you have the hazardous material in your home and the best process for removing or sealing it.

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

Yes, even a single, one-time exposure to asbestos can be harmful and increase the risk of future illness, including certain diseases and cancers. The level of risk depends on several factors, such as the concentration and intensity of the exposure. A small, brief exposure is less likely to cause significant damage than an exposure to a high concentration of asbestos fibers.

The likelihood of developing severe health issues increases with repeated or prolonged exposure. Individual reactions to asbestos vary; some people may have multiple exposures without harm, while others are more susceptible. Asbestos-related illnesses may not manifest for 10 to 40 years after inhalation.

Due to these risks, it is crucial to take precautions. Personal protective equipment (PPE) may not offer complete protection, as fibers can get through small gaps. The EPA recommends hiring a professional for testing and removal if you suspect the presence of asbestos in your home. If you are concerned about a potential exposure, consult your doctor.

No, an N95 mask will not protect against asbestos and many other hazardous materials, such as carbon monoxide, gas, chemical vapors, and other gases. You will need a respirator specifically designed to protect against asbestos. However, if you suspect asbestos is present in your home, hire an asbestos abatement professional immediately and avoid the area until they arrive for the inspection.

Federal law doesn’t require homeowners to disclose the presence of asbestos in their home, but some states and local municipalities may require it. That is why it’s important to test an older home for asbestos and other health hazards before moving forward with a sale.
