Asbestos in Your Home: Where is it Located?

If your home was built before the 1980s, there’s a good chance that asbestos-containing materials (ACMs) are present in various areas of your house. Asbestos was widely used in construction due to its fire-resistant and insulating properties. While it can pose significant health risks, such as lung cancer and mesothelioma, asbestos is generally not dangerous if it’s in good condition and left undisturbed. However, when asbestos fibres become airborne—through damage or disturbance—they can be inhaled, leading to serious health issues.

Whether you rent or own a home, it’s essential to understand where asbestos might be located so you can monitor for any damage and minimize your exposure to asbestos. This guide provides valuable insights into common areas where asbestos may be found, what to look for, and what steps to take if you suspect asbestos in your home.

Exterior Asbestos Risks

The exterior of homes built before the 1980s may contain asbestos in various materials. While these materials are less likely to be disturbed, it’s still important to be vigilant and check for damage regularly. Asbestos-containing materials on the exterior of a home may include:

• Gutters
• Roofing materials: Tar paper, flat roof coverings, and sometimes shingles
• Soffits made with Asbestos Insulating Board (AIB)
• Window putty and exterior window panels
• Deck undershooting

Why asbestos was used: In exterior applications, asbestos was commonly added to materials for its durability and weather-resistant properties. However, exposure to the elements can cause wear and tear over time, making the asbestos fibres more likely to be released into the air.

What to look for:

1. Check for cracks, wear, or other visible damage to materials like roofing or soffits.
2. If you notice signs of deterioration, contact an asbestos removal professional for inspection.
3. Never attempt to repair or remove materials yourself, as improper handling can disturb asbestos fibres.

Interior Asbestos Risks

Inside the home, asbestos can be more dangerous due to frequent human contact and the potential for disturbance. Asbestos containing materials (ACMs) may be present in various parts of your home, especially if it was built or renovated before the 1980s. The most common places asbestos might be found inside the home include:

• Basement:
  • Heat source coverings (e.g., around boilers or furnaces)
  • Air duct linings
  • Water heaters
  • Clothes dryers
• Throughout the house:
  • Vinyl flooring and tiles: Asbestos was often added to vinyl products for strength and durability.
  • Sprayed-on acoustical ceilings: Known as “popcorn ceilings,” these often contain asbestos.
  • Textured paints and wall treatments.
  • Blown-in or batt insulation: Older insulation products frequently use asbestos fibres for fireproofing.
  • Wood stoves and fireplaces: Some older stoves or fireproofing materials around fireplaces may contain asbestos.
• Unexpected household items:
  • Ironing board pads and pot holders: These heat-resistant items often contain asbestos for their fireproof qualities.

Health risks: Inhalation of asbestos fibres can lead to severe health conditions, such as asbestosis, mesothelioma, and lung cancer. According to the American Lung Association, these diseases may develop years or even decades after exposure. This makes it vital to avoid disturbing materials that may contain asbestos.

What to Do if You Suspect Asbestos

If you suspect that materials in your home contain asbestos, or if you find damaged asbestos materials, follow these steps to protect yourself and your family:

1. Do not disturb the material.
   • Avoid touching, drilling, cutting, or moving the suspected asbestos-containing materials. Even minimal disturbance can release dangerous asbestos fibres into the air.
2. Contact an asbestos professional.
   • Hire a licensed asbestos inspector or removal contractor certified by local authorities or an organization like the EPA or the Asbestos Hazard Emergency Response Act (AHERA). Certified professionals have the equipment and expertise to inspect and remove asbestos safely.
3. Get professional testing.
   • A licensed asbestos inspector can collect samples safely and send them to a laboratory for analysis. Never attempt to take samples yourself, as this can cause exposure to harmful fibres.
4. Plan for removal or containment.
   • A professional can advise whether removal or containment is the best option if asbestos is found. In many cases, asbestos in good condition and not disturbed may be left alone and encapsulated to prevent future damage.
5. Follow legal guidelines.
   • Asbestos removal is regulated by strict guidelines to protect public health. Work with professionals who follow EPA or OSHA (Occupational Safety and Health Administration) guidelines to ensure that removal is done safely and complies with local laws.

Health Risks of Asbestos Exposure

Exposure to asbestos fibres can cause several severe health conditions, including:

• Mesothelioma: A rare but aggressive cancer that develops in the lining of the lungs, abdomen, or heart.
• Asbestosis: A chronic lung condition caused by inhaling asbestos fibres, leading to lung scarring and breathing difficulties.
• Lung cancer: Inhalation of asbestos fibres can increase the risk of lung cancer, especially for those who smoke.

According to the Centers for Disease Control and Prevention (CDC), asbestos-related diseases can take 10 to 40 years to develop, making early identification and removal of asbestos critical to preventing long-term health risks.

How to Hire a Certified Asbestos Professional

If you need to hire an asbestos removal professional, here are some tips to ensure you get qualified help:

• Look for certified professionals: Use directories the EPA or AHERA provides to find licensed asbestos inspectors and abatement contractors in your area.
• Ask about certifications: Ensure the contractor is certified by a recognized authority, such as AHERA or OSHA, and ask for proof of their qualifications.
• Request a detailed plan: The contractor should provide a written plan outlining the scope of work, the safety precautions they will take, and the timeline for removal or containment.

Conclusion

Asbestos can be found in many areas of homes built before the 1980s, from roofing materials to insulation and even household items like ironing board pads. While asbestos poses health risks when disturbed, it is manageable with the proper precautions. Regular monitoring, safe handling, and professional inspections are crucial to minimizing exposure. If you suspect asbestos in your home, never attempt to remove it yourself. Instead, contact a certified asbestos professional who can safely assess the situation and recommend the best action.

By following these steps, you can protect yourself and your family from the dangers of asbestos exposure and ensure a safer living environment.
