Loucas LoucaidesHome Improvement, Renovation 3 Comments


In the 1970s, stucco ceilings, also known as popcorn ceilings or acoustic ceilings, were a popular choice for many homes and commercial spaces. This textured ceiling finish was not only fashionable but also provided acoustic benefits by reducing noise levels. However, what was once a trendy design element now poses a potential health hazard. Many stucco ceilings from that era contain asbestos, a harmful mineral fiber that can lead to serious health issues if released into the air. In this blog, we will explore the importance of testing for asbestos in 1970s stucco ceilings and discuss safe removal options.

Understanding Asbestos

Asbestos is a naturally occurring mineral that was commonly used in construction materials until its harmful effects became widely known. The mineral’s fibrous nature makes it resistant to heat, fire, and chemicals, which made it a popular choice in various building applications. However, prolonged exposure to asbestos fibers can lead to severe health conditions, including lung cancer, asbestosis, and mesothelioma.

The risk in 1970s stucco ceilings

Stucco ceilings installed during the 1970s are known to contain asbestos. The textured appearance of these ceilings was achieved by mixing asbestos fibers with the stucco material. When the ceiling remains undisturbed, the asbestos fibers are typically contained within the stucco matrix. However, over time, the ceiling may deteriorate or get damaged, releasing these dangerous fibers into the air where they can be inhaled.

The importance of Testing

If your home or property was built during the 1970s and features a stucco ceiling, it is crucial to determine whether it contains asbestos. Testing the ceiling for asbestos is the only way to know for sure. Professional asbestos inspectors can collect samples and send them to certified laboratories for analysis. They will perform a thorough examination, identifying the presence and concentration of asbestos fibers in the stucco ceiling.

Safe asbestos removal

 If the test confirms the presence of asbestos in your stucco ceiling, it is highly recommended to proceed with safe removal. While it is technically possible for homeowners to remove asbestos-containing materials themselves, it is a complex and hazardous process that should be left to professionals. Certified asbestos abatement contractors have the necessary expertise, equipment, and safety protocols to ensure the safe removal and disposal of asbestos materials. Type 2 and type 3 Abatement is regulated by law in the Province of Ontario.

The process of asbestos removal typically involves the following steps:

  1. Containment: The work area is carefully sealed off to prevent the spread of asbestos fibers to other parts of the property.
  2. Personal Protective Equipment (PPE): Workers wear appropriate PPE, including respirators, disposable coveralls, and gloves, to protect themselves from exposure.
  3. Wetting: The stucco ceiling is thoroughly wetted to minimize the release of asbestos fibers during removal.
  4. Careful Removal: The stucco ceiling is carefully scraped off or removed in sections, minimizing dust generation.
  5. Cleanup: The work area is meticulously cleaned using specialized vacuum cleaners designed to capture asbestos fibers.
  6. Disposal: All asbestos-containing materials are properly sealed and disposed of at authorized waste disposal facilities.


If your property features a stucco ceiling installed during the 1970s, it is crucial to have it tested for asbestos. The health risks associated with asbestos exposure make it imperative to approach the situation with caution. If asbestos is detected, hiring a professional asbestos abatement contractor is highly recommended for safe removal. By taking the necessary steps, you can ensure the protection of yourself, your loved ones, and anyone else who occupies the space, creating a safer living or working environment for all.


1.  When did Asbestos stop being used in construction?  Asbestos was used extensively in residential construction until the late 1970’s and early 1980’s. It was used in commercial construction until the late 1990’s at which time its use was regulated by the government.

2.  I am only installing pot lights on a stucco ceiling. Do I still need to test for asbestos? To install pot lights, holes have to be drilled on the ceiling therefore the stucco gets disturbed and becomes airborne. Testing is highly recommended.

3.  Can any contractor remove asbestos material? No, asbestos abatement requires training and certification. Specific protocols have to be followed during the abatement.

4.  Can I throw away asbestos-containing material in the garbage? No, asbestos-containing material can only be disposed at a specific government run dump site.

  1. You were spot on in reminding us that safety gear must be donned when handling asbestos to prevent health hazards. My neighbor seems pretty adamant that the storeroom in his backyard might’ve been contaminated with such a substance. Well, time for him to call an abatement company to deal with the issue.

  2. Your statement that asbestos removal calls for training and certification caught my attention. During the abatement, specific procedures must be followed. I believe asbestos testing should come first before my husband and I renovate our house. I’ll have to check into locating the finest business in my region to conduct an asbestos test. Thank you for sharing this.

  3. Asbestos is a naturally occurring mineral that was widely utilized in construction materials until its detrimental effects were generally understood. I am so happy I found your blog and I love the information you have provided. What was once a hip component of decor may now be harmful to people’s health. Asbestos, a dangerous mineral fiber, can be found in many stucco ceilings from that era can cause serious health problems if released into the air. This blog post will explain why it’s critical to check stucco ceilings built in the ’70s for asbestos and cover methods for doing so safely. Excellent material!
