Percolation Tests questions, answered by experts

If your home was built before 1989 and still has original vinyl, there’s a high probability of asbestos mixed into the old flooring, which can harm you and your family if it’s disturbed from removal. If you suspect that you have asbestos, you’ll want to call in an asbestos removal expert to evaluate the situation.

Knob and tube wiring is an older type of electrical wiring that's no longer used and generally not considered safe. However, some homes still have it, or may have a knob and tube wiring system that was incorrectly modified or rigged to work with a modern electrical system. Knob and tube wiring may contain asbestos insulation, but the only way to know is to have the material professionally tested.

The signs of asbestos exposure are often subtle and may not appear for many years, or even decades, after initial contact. This long latency period is one of the primary dangers associated with asbestos.

When symptoms do manifest, they can include:

  • Shortness of breath

  • A persistent, dry cough

  • Chest pain or tightness

  • Fatigue

  • Wheezing

  • Weight loss

  • Difficulty swallowing

  • A dry, crackling sound from the lungs when breathing

These symptoms are non-specific and can be mistaken for other respiratory conditions, making diagnosis challenging. Prolonged exposure can lead to serious diseases as the asbestos fibers cause scarring and inflammation in the lungs. These conditions include asbestosis, lung cancer, and mesothelioma.

Due to the vague nature of early symptoms, regular medical check-ups are crucial for anyone with a known history of asbestos exposure, particularly in an occupational setting. If you suspect asbestos is present in your home, a professional inspection is recommended.

The Environmental Protection Agency (EPA) banned the use of asbestos pipe insulation in certain applications in 1975. It released further bans in 1989 and 2019. While asbestos pipe insulation was common from the 1930s to 1970s, its use fell off after the 1970s due to public concern and the EPA's actions.

According to the Environmental Protection Agency (EPA), you should contact the following officials to report a case of asbestos exposure:

  • Asbestos subject matter experts in your state 

  • EPA regional office

  • Toxic Substances Control Act (TSCA) Assistance Information Service Hotline via mail, email, or phone

  • EPA’s Asbestos Ombudsman via phone or fax
