If your home was built in 1986, you might be wondering, “Would a house built in 1986 have asbestos?” This is a crucial question because asbestos, widely used in construction materials in the 20th century, poses serious health risks. Known for its fireproofing and insulating properties, asbestos was once considered a miracle material. However, over time, it became evident that exposure to asbestos could lead to severe health conditions, including mesothelioma, asbestosis, and lung cancer.
By the mid-1980s, regulatory measures had begun to limit asbestos use in residential Construction, but it wasn’t entirely banned in many countries until years later. This makes homes built around 1986 a borderline case: they may or may not contain asbestos materials. As a homeowner, it’s vital to understand whether your home has asbestos and how to address it safely.
Understanding Asbestos and Its Use in Homes
What Is Asbestos?
Asbestos is a group of naturally occurring minerals composed of tiny, durable fibres that are heat-resistant, fireproof, and excellent insulators. These properties made it a popular choice in the construction industry throughout much of the 20th century.
However, when asbestos-containing materials (ACMs) are disturbed, they release microscopic fibres into the air. These fibres can be inhaled or ingested, leading to severe health conditions over time.
Common Asbestos-Containing Materials
In homes built before and around 1986, asbestos was commonly used in:
- Flooring materials (e.g., vinyl tiles, linoleum).
- Ceiling textures (e.g., popcorn ceilings).
- Pipe insulation (used to prevent heat loss).
- Cement sheets (used in roofing and siding).
- Adhesives and joint compounds.
Timeline of Asbestos Use and Ban
The use of asbestos peaked in the mid-1900s, but concerns about its health risks began to emerge in the 1970s. By the mid-1980s, restrictions on the use of asbestos in residential Construction were in place in many countries. However, the transition wasn’t immediate. Some builders continued using leftover materials containing asbestos, making homes built in 1986 a “grey area.”
Health Risks of Asbestos Exposure
Exposure to asbestos can lead to serious health conditions, including:
- Mesothelioma: A rare and aggressive form of cancer affecting the lining of the lungs, abdomen, or heart.
- Asbestosis: A chronic lung disease caused by inhaling asbestos fibres.
- Lung cancer: Prolonged exposure increases the risk of cancer, especially for smokers.
Because of these risks, it’s essential to identify and manage asbestos-containing materials in your home.
Would a House Built in 1986 Have Asbestos?
Asbestos Use in 1980s Construction.
By 1986, the use of asbestos in residential Construction had decreased significantly due to growing awareness of its dangers. However, asbestos was not entirely banned in many countries, and some builders continued to use materials containing asbestos, especially if they had existing stockpiles of these materials.

Factors Influencing Asbestos Presence
Several factors determine whether a 1986-built home contains asbestos:
- Location: Regions with stricter regulations may have phased out asbestos faster.
- Builder Practices: Some builders prioritized safer materials, while others continued to use asbestos products.
- Renovation History: Homes that have undergone renovations may have introduced or removed asbestos materials.
Common Asbestos Materials in 1986 Homes
Here are some materials where asbestos might be found in a home from this era:
- Vinyl Floor Tiles: Particularly 9×9-inch tiles, which often contain asbestos.
- Ceiling Tiles: Textured or corrugated tiles may include asbestos.
- Pipe Insulation: Frequently used to insulate pipes and boilers.
- Roofing and Siding: Cement sheets and shingles often contained asbestos.
Likelihood of Asbestos in a 1986 Home
While homes built in 1986 are less likely to have asbestos than those built in earlier decades, the possibility still exists. It’s essential to evaluate your home carefully, especially if you plan renovations or repairs.
Signs to Look for to Identify Potential Asbestos
Visual Indicators of Asbestos
While you cannot confirm asbestos presence with a visual inspection alone, certain materials are more likely to contain asbestos:
- Flooring: Old vinyl tiles or linoleum sheets.
- Ceilings: Popcorn textures or pressed ceiling tiles.
- Pipes: Insulation that looks white, grey, or flaky.
- Roofing and Siding: Cement-based shingles or panels.
Areas to Inspect in Your Home
Flooring
Check for old vinyl or linoleum tiles, especially if they measure 9×9 inches. These tiles often contained asbestos.
Ceilings
Popcorn ceilings or heavily textured tiles from the 1980s may contain asbestos.
Pipes and Boilers
Insulation materials used around pipes and boilers in older homes were often made with asbestos.

Caution: Do Not Disturb Suspected Materials
It’s crucial not to disturb potential asbestos-containing materials. Disturbance can release hazardous fibres into the air, thereby increasing exposure risks.
How to Test for Asbestos in Your 1986 Home
Professional Testing vs. DIY Kits
Professional Testing
Hiring a certified asbestos professional is the safest and most reliable way to test for asbestos. They utilize advanced equipment and adhere to strict safety protocols.
DIY Asbestos Testing Kits
While available, these kits require careful handling. Improper use can release asbestos fibres, posing health risks.
Step-by-Step Guide for Testing
- Determine When to Test
- Test before any renovations, demolitions, or if you notice damaged materials.
- Hire a Certified Professional
- Search for licensed asbestos inspectors in your area. They have the expertise to identify and test materials safely.
- Sample Collection
- If you opt for DIY testing, wear protective gear and avoid disturbing the material. Send the sample to a certified laboratory for analysis.
- Laboratory Analysis
- Labs use methods like PLM (Polarized Light Microscopy) or TEM (Transmission Electron Microscopy) to confirm asbestos presence.
What to Do If Asbestos Is Found
Intact vs. Damaged Asbestos
- Intact Materials: If asbestos-containing materials are undisturbed and in good condition, they may be left in place and monitored.
- Damaged Materials: These must be addressed immediately to prevent fibre release.
Professional Asbestos Removal
Asbestos removal should always be performed by licensed specialists. They follow strict regulations and use protective equipment to ensure safe removal.
Legal and Safety Regulations
Most countries have strict laws governing the removal and disposal of asbestos. Violating these laws can result in hefty fines.
Preventive Measures and Safety Tips
- Regular Monitoring: Inspect asbestos-containing materials periodically for signs of damage.
- Avoid Disturbance: Minimize drilling, sanding, or cutting materials that may contain asbestos.
- Inform Contractors: Notify contractors about potential asbestos before renovations.
