Asbestos In Older Homes

CHEMICAL DANGERS

Key Concerns

Asbestos poses serious health risks when materials containing it are disturbed, often during renovations or repairs. Common in older homes, asbestos may be found in insulation, floor tiles, ceilings, and pipe wraps. When damaged, it releases tiny fibers into the air that, if inhaled, can cause lung diseases such as asbestosis, mesothelioma, and cancer. The two main types of asbestos — chrysotile and amphibole — are both linked to disease development. These illnesses often go undetected until a doctor performs a thorough examination, making asbestos especially dangerous due to its silent and long-term effects. Because there is no safe level of exposure and asbestos is difficult to detect without testing, certified professionals should always handle inspection and removal

Building Materials

In homes built before the 1980s, asbestos was commonly used in a variety of construction materials due to its fire-resistant and insulating properties. Common sources include insulation around pipes and furnaces, vinyl floor tiles, popcorn ceilings, roofing shingles, siding, and joint compounds used on walls and ceilings. When these materials age, become damaged, or are disturbed during renovations, they can release harmful asbestos fibers into the air.

How to Limit & Avoid Risks Associated with Asbestos

  • Do not disturb materials you suspect may contain asbestos (e.g., old tiles, pipe insulation, or ceiling textures).
  • Avoid sanding, drilling, or scraping any suspected asbestos-containing surfaces.
  • Hire a certified asbestos inspector before beginning renovations in older homes (especially those built before 1980).
  • Seal or encapsulate asbestos-containing materials if removal is not immediately necessary and they are in good condition.
  • Ensure proper ventilation in older attics or basements where asbestos insulation may be present.
  • Never attempt DIY removal — always use licensed asbestos abatement professionals.
  • Regularly check for wear or damage in older building materials and report any deterioration.
  • Educate household members on what asbestos is and where it may be found.

Frequently Asked Questions

1. Where is asbestos commonly found in older homes?
Asbestos may be found in insulation, vinyl floor tiles, ceiling tiles, popcorn ceilings, pipe wraps, siding, roofing shingles, and joint compound used on drywall seams—especially in homes built before 1980.

2. Is asbestos dangerous if it’s not disturbed?
When left intact and undisturbed, asbestos-containing materials generally pose little risk. The danger arises when these materials are damaged, deteriorating, or disturbed during renovation, which can release harmful fibers into the air.

3. How can I tell if a material contains asbestos?
You cannot tell by simply looking at a material. The only way to confirm the presence of asbestos is through professional testing by a certified asbestos inspector or lab.

4. What health problems can asbestos exposure cause?
Inhaling asbestos fibers over time can lead to serious health conditions, including asbestosis, mesothelioma, lung cancer, and other respiratory issues. These diseases often develop many years after exposure.

5. Can I remove asbestos from my home myself?
No. Asbestos removal should always be handled by licensed professionals trained in proper containment and disposal methods. Attempting to remove it yourself can worsen exposure risks.

6. What should I do if I think there is asbestos in my home?
Avoid disturbing the material and contact a certified asbestos professional to inspect and test the area. If necessary, they can guide you through safe encapsulation or removal.
