The Hidden Danger of Asbestos in Older Houses

by Martin

If you’re renovating an older home, especially those built between the 1930s and 1970s, it’s important to be aware of the construction materials and the possibility products containing asbestos were used in the building.


This is an important reminder to ensure you’re aware of the potential risks of asbestos and to encourage you to take the necessary precautions.


If you suspect asbestos, don’t attempt any DIY work. Have the area checked out thoroughly by an asbestos removal company.  Call in licensed, trained professionals and have the product safely removed from the home.

Why were Asbestos materials used in building?

The product was known for its durability, heat resistance, and insulating properties which made it a popular choice and was commonly used in construction during that era. Asbestos was used in wall and ceiling sheeting as well as spray-on ceiling products, particularly in areas prone to moisture like bathrooms, kitchens, and laundry rooms.


This is a list of some locations where it may be present:

  • Insulation materials (such as attic insulation, wall insulation, and pipe insulation)
  • Ceiling tiles
  • Floor tiles and adhesive
  • Roofing and siding materials
  • Textured paint and patching compounds
  • HVAC duct insulation
  • Vermiculite insulation
  • Electrical wiring insulation

Why is Asbestos dangerous?

It’s a fibrous material and the tiny fibers, although invisible to the naked eye, can become airborne when disturbed and pose serious health risks if inhaled.

During the 1970s, the risks to our health became increasingly recognized. An awareness of the danger and toxicity of asbestos was growing. Its use in some products continued until the mid-1980s. Now, thankfully, many countries have banned its use or have heavily regulated the use of asbestos products.


Homes built before 1980 are at a higher risk of containing asbestos in their building materials compared to newer builds.
