Asbestos has a long and controversial history in the construction industry. Throughout much of the 20th century, it was widely used in homes for its unique properties, including fire resistance, insulation, and durability. However, as the health risks of asbestos became apparent, its use declined, and regulations were introduced to limit or ban it. But what about homes built in 1985? Would they still have asbestos.
What Is Asbestos?
Asbestos is a naturally occurring mineral composed of tiny, durable fibers. These fibers are resistant to heat, electricity, and chemical damage, which made asbestos a popular choice for various industrial and construction applications.
Why Was Asbestos Popular in Construction?
Asbestos was widely used in construction materials due to its fire-resistant properties, insulation capabilities, and long-lasting durability. It was incorporated into everything from insulation and cement to floor tiles and roofing materials. Its versatility made it an attractive material for builders in the 20th century.
Types of Asbestos
There are six recognized types of asbestos, but the three most commonly used in construction include:
- Chrysotile (White Asbestos): The most commonly used type, often found in cement, insulation, and roofing materials.
- Amosite (Brown Asbestos): Known for its heat resistance, it was frequently used in insulation and cement sheets.
- Crocidolite (Blue Asbestos): The least heat-resistant type but highly durable, often used in pipe insulation and spray-on coatings.
Each type carries risks, with crocidolite and amosite being more dangerous due to their brittle nature and ability to release fibers easily.
The History of Asbestos Use in Homes
The use of asbestos in homes has a long history, peaking in the mid-20th century before regulatory measures began to restrict its application.

Peak Usage: 1930s–1970s
Asbestos was widely used in homes from the 1930s through the 1970s. It was included in various building materials, such as insulation, floor tiles, and cement. During this period, its affordability and effectiveness made it a go-to material.
Decline in the 1980s
By the 1980s, awareness of the severe health risks associated with asbestos exposure—including asbestosis, lung cancer, and mesothelioma—led to increasing public concern. As a result, many countries began introducing regulations and bans to reduce their use. However, asbestos was not entirely phased out in 1985 and remained in some products.
Was Asbestos Used in 1985?
The short answer is: Yes, asbestos was still in use in 1985, but its application had significantly declined compared to earlier decades. Let’s break this down further.
Products Containing Asbestos in 1985
By 1985, many countries had already restricted or banned certain asbestos types, such as blue (crocidolite) and brown (amosite). However, white asbestos (chrysotile) was still permitted in various products. These included:
- Vinyl floor tiles and adhesives
- Cement sheets and pipes
- Roofing shingles
- Textured ceiling coatings (e.g., popcorn ceilings)
In some cases, builders might have used materials manufactured before 1985, which could still contain asbestos.

Regional Differences in Regulations
The use of asbestos varied by country in 1985. For example:
- United Kingdom: The UK introduced the Asbestos Prohibition Regulations in 1985, banning blue and brown asbestos. However, white asbestos was still allowed.
- United States: Regulations like the Toxic Substances Control Act (TSCA) restricted some asbestos uses, but it wasn’t entirely banned.
- Canada: Asbestos use was phased out gradually, with restrictions starting in the late 1970s.
- Australia: Asbestos was widely used in construction until a full ban was implemented in 2003.
This means that homes built in 1985 may still contain asbestos, depending on the region and the materials used.
Common Asbestos-Containing Materials in 1985 Homes
If your house was built in 1985, knowing where asbestos might be hiding is essential. Here are some common materials that could contain asbestos:
Material Where It’s Found
Insulation Walls, attics, and around pipes
Vinyl floor tiles and adhesives for Kitchens, bathrooms, and basements
Popcorn/textured ceilings , Living rooms, hallways, and bedrooms
Roofing shingles and siding , Exterior of the home
Cement boards and panels , Walls, floors, and ceilings
How to Identify Potential Asbestos Materials
While some asbestos materials are easy to spot, others are not. For example, popcorn ceilings often contain asbestos, but it’s impossible to confirm without professional testing. Be cautious when inspecting materials; disturbing them could release harmful asbestos fibers into the air.
Where Is Asbestos Most Likely to Be Found in a 1985 House?
Asbestos-containing materials can be found throughout a home, but certain areas are more likely to harbor them. Here’s a room-by-room breakdown:
Attics and Wall Cavities
Insulation, especially loose-fill insulation like vermiculite, often contained asbestos. This is particularly common in homes built between the 1940s and 1980s.
Kitchens and Bathrooms
Vinyl floor tiles and their adhesives frequently included asbestos. These materials were durable, water-resistant, and easy to maintain.
Basements
Basements often had pipe insulation or boiler insulation made with asbestos. If your home has an older furnace or boiler, it’s worth checking for asbestos-containing materials.
Ceilings
Popcorn ceilings were trendy in the 1980s and frequently contained asbestos. These ceilings are easy to identify by their textured, bumpy finish.
Exterior
Roofing shingles, siding, and cement products on the exterior of homes often contained asbestos for added durability and weather resistance.
Health Risks Associated with Asbestos Exposure
Asbestos exposure occurs when its fibers are released into the air and inhaled. This typically happens when asbestos-containing materials are disturbed, such as during renovations or demolition.
Common Health Risks
- Asbestosis: A chronic lung condition caused by scarring from asbestos fibers.
- Lung Cancer: Prolonged asbestos exposure significantly increases the risk of lung cancer.
- Mesothelioma: A rare and aggressive cancer that affects the lining of the lungs, chest, or abdomen.
Is Undisturbed Asbestos Safe?
Asbestos-containing materials generally pose a lower risk if they remain intact and undisturbed. However, materials can degrade over time, increasing the likelihood of fiber release.
How to Determine if Your 1985 Home Has Asbestos
To determine whether your home contains asbestos, follow these steps:
- Check Building Records: Look for permits or records that indicate the materials used during construction.
- Conduct a Visual Inspection: Look for materials commonly known to contain asbestos, but avoid disturbing them.
- Hire a Professional: Certified asbestos inspectors can conduct surveys and testing to confirm the presence of asbestos.
What To Do If You Suspect Asbestos in Your Home
If you suspect asbestos in your home, do not disturb it. Here’s what you should do instead:
- Call a Professional: Hire a certified asbestos removal specialist for inspection and abatement.
- Follow Safety Protocols: Ensure the area is sealed to prevent fiber release.
- Consider Removal: Professional removal is the safest option if asbestos poses a risk.
Renovation and Asbestos: What Homeowners Need to Know
If you’re planning to renovate a 1985 home, you must take precautions:
- Conduct Asbestos Testing: Before starting any work, test for asbestos in walls, ceilings, and floors.
- Hire Licensed Contractors: Ensure contractors are trained in safe asbestos handling.
- Follow Regulations: Comply with local asbestos regulations to avoid legal and health risks.
