Asbestos is a dangerous substance that was widely used in construction materials until the late 20th century. It’s a material that was prized for its fireproofing, insulating, and durability properties. However, it can also cause serious health problems when disturbed, including lung cancer, asbestosis, and mesothelioma. Many people don’t realize that their homes could still contain asbestos, especially in older properties. The danger lies in the fact that asbestos becomes hazardous when disturbed, releasing fibers into the air. These fibers can be inhaled, leading to long-term health risks.
If you suspect that your home might contain asbestos, asbestos removal should be your top priority before starting any demolition or renovation work. In this article, we’ll discuss 9 hidden signs that your home may contain asbestos-containing materials (ACMs), and why it is crucial to act before undertaking any major work.
1. Your Home Was Built or Renovated Before 1990
If your home was built or last renovated before 1990, there is a high likelihood that it contains asbestos. Asbestos was commonly used in building materials during the mid-20th century, including in insulation, roofing materials, and flooring. Homes built during or before this period may have asbestos in places like ceiling tiles, floor coverings, and wall insulation.
Homes constructed before 1990 are more likely to have asbestos-containing materials (ACMs) hidden in plain sight. It’s essential to have an asbestos survey done if you live in an older home, as the risks increase with age.
2. Textured Ceilings, “Popcorn” Coatings, or Artex Finishes
One of the most common places where asbestos can be found in older homes is in textured ceiling finishes, commonly known as popcorn ceilings. These ceilings were particularly popular in the 1960s and 1970s for their ability to hide imperfections and provide fireproofing.
If your home has these types of textured ceilings, it is important to be cautious. When disturbed, they can release asbestos fibers into the air, which are dangerous when inhaled. Cracks or wear and tear on these surfaces should prompt an immediate asbestos inspection.
3. Vinyl Floor Tiles, Linoleum, or Other Flooring Materials
Old vinyl floor tiles, especially those with a 9″ x 9″ or 12″ x 12″ design, are often made from asbestos-containing materials. If you have flooring that dates back to the 1970s or 1980s, it may contain asbestos in the adhesive or backing materials.
Asbestos-containing floor tiles can be dangerous if disturbed during renovation or repair work. If you plan to remove old flooring, it is important to have it tested for asbestos beforehand to avoid exposure to airborne fibers.
4. Insulation Around Pipes, Ductwork, and Heating Systems
Another place where asbestos can be found in older homes is in the insulation around pipes, ductwork, and heating systems. Insulation made from asbestos was commonly used in homes built before the 1980s to provide thermal insulation and fireproofing.
If you notice insulation around pipes or ducts that is fraying, damaged, or deteriorating, it’s crucial to have it tested for asbestos. Disturbing this material during renovations can release toxic fibers into the air.
5. Corrugated Roofing Sheets, Gutters, Soffits, or External Panels
Asbestos was used in corrugated roofing sheets, guttering, and soffits in many homes built before the 1980s. If your home has old roofing or cladding made from these materials, it may contain asbestos. These materials can become fragile and break down over time, releasing asbestos fibers into the environment.
Asbestos-containing roofing materials are particularly dangerous during renovation or demolition work. Always have your roofing materials inspected before starting any work.
6. Fireproofing Materials in Older Fireplaces or Wood Stoves
If your home has an older fireplace, wood stove, or furnace, it may contain asbestos-based fireproofing materials. These materials, known as asbestos insulating boards (AIBs), were commonly used in older homes to protect against fire. These boards can deteriorate over time, releasing asbestos fibers.
When renovating or removing older fireplaces or stoves, it is crucial to have these materials tested for asbestos before disturbing them.
7. Visible White Dust or Fibrous Materials Around Suspect Areas
Sometimes, asbestos fibers are not visible unless the materials have been disturbed. However, if you notice fine white dust or fibers around areas that might be asbestos-containing, such as pipes, insulation, or ceilings, this could be a sign that the materials are deteriorating and releasing fibers into the air.
If you see or suspect that asbestos fibers are present, avoid disturbing the materials and contact a licensed asbestos professional immediately.
8. Cracking, Delamination, or Flaking of Older Mastic, Plaster, or Adhesives
Asbestos was also used in adhesives, plaster, and mastic (the material used to attach tiles and other finishes to surfaces). If you notice old adhesives or plaster starting to crack, peel, or flake, this could be a sign that the materials contain asbestos. Damaged plaster or mastic materials may release fibers when disturbed.
During renovations or restorations, it’s essential to check the condition of old plaster and adhesives before disturbing them to prevent exposure to asbestos.
9. Absence of Visible Labelling or Documentation in Materials
In homes built before asbestos regulations were put into place, many materials may not have clear labels indicating that they contain asbestos. Even though asbestos was commonly used in building materials, many products were not labelled with warnings, especially in homes built before the 1980s.
If you don’t see any labels or documentation on your materials, it’s wise to err on the side of caution and have them tested for asbestos. If you’re unsure whether something contains asbestos, get it inspected by a professional.
Why You Must Act Before Demolition or Renovation
Health Implications
Asbestos is a health risk that should never be taken lightly. If asbestos fibers are inhaled, they can lead to serious respiratory diseases, including lung cancer, mesothelioma, and asbestosis. Disturbing asbestos during demolition or renovation work can release dangerous fibers into the air. Even a small disturbance can trigger the release of airborne fibers, which can remain suspended for long periods of time, creating an ongoing health hazard for anyone in the area.
Legal and Liability Issues
When working with or removing asbestos, there are strict legal requirements that must be followed. Failing to properly manage asbestos can lead to legal liability for property owners. If asbestos is disturbed without the proper procedures, you may be held accountable for any harm caused to workers or others who are exposed to the fibers.
Cost and Delays
Ignoring asbestos in your home can lead to unexpected costs and delays during renovation or demolition projects. If asbestos is discovered after work has already begun, the process of removing it can be time-consuming and expensive. It’s important to have an asbestos survey before starting any work to avoid project delays and additional costs.
Next Steps: What to Do if You Suspect Asbestos in Your Home
- Do not disturb any suspicious materials. Avoid handling, scraping, or sanding areas where asbestos might be present.
- Schedule an asbestos survey with a licensed professional to inspect and test materials.
- If asbestos is found, hire a licensed asbestos removal contractor to safely remove and dispose of the material.
- After removal, ensure the area is cleared and tested for asbestos before resuming renovation or demolition work.
Conclusion
If your home exhibits any of the 9 hidden signs discussed above, it’s essential to take immediate action. The presence of asbestos in your home is not something to ignore, especially if you are planning demolition or renovation. Identifying and removing asbestos before starting any major work will not only protect your health but also ensure that your project proceeds smoothly and safely. Always consult a licensed professional for proper asbestos removal to avoid health risks and legal issues.
