Asbestos in Home Building: What Every Homeowner Should Know
Asbestos is a naturally occurring mineral that was widely used in home construction from the early 1900s through the late 1970s. It was valued for its fire resistance and durability. Today, it is known to cause serious illness. Homes built before the 1980s may still contain it.
Asbestos was once considered a wonder material for home builders. It was cheap, durable, and fireproof. For decades, it was built into the walls, floors, and ceilings of American homes without a second thought. We now know that those same properties that made asbestos so useful also make it dangerous. In this blog, we will discuss what asbestos is, how it was used in residential construction, why it is no longer used today, and how Safer Homes Environmental can help with our asbestos inspection and indoor air quality services across New Hampshire, Northern Massachusetts, Eastern Vermont, and Southern Maine.
What Is Asbestos and What Does an Asbestos Inspection Look for in Older Homes?
Asbestos is a naturally occurring silicate mineral made up of thin, microscopic fibers. An asbestos inspection looks for building materials that may contain these fibers. Common locations include pipe insulation, floor tiles, popcorn ceilings, drywall joint compound, roofing felt, and attic insulation. In older homes, asbestos can appear almost anywhere a builder needed a fireproof or heat-resistant material.
Why Was Asbestos Used in Residential Construction for So Long?
Asbestos was used because it was highly effective. It resisted heat, fire, and chemical damage. It also improved the durability of building products and provided strong acoustic and thermal insulation. Builders and manufacturers relied on it heavily during post World War II housing booms, when new homes were being built quickly and affordably across the country. For most of the 20th century, it was considered a safe and practical choice.
When Did Homes Stop Using Asbestos in Construction?
Asbestos use in home building began to decline in the 1970s as health concerns became widely recognized. The U.S. Environmental Protection Agency (EPA) began restricting specific asbestos-containing products starting in 1973. Most building material manufacturers had phased out asbestos by the early 1980s. However, homes built or renovated before that period may still contain asbestos materials that were never removed.
What Are the Health Risks of Asbestos? Should You Get an Asbestos Inspection?
Asbestos is dangerous when its fibers become airborne and are inhaled. According to the National Institute for Occupational Safety and Health (NIOSH), there is no known safe level of asbestos exposure. Inhaled fibers can lodge in lung tissue and cause serious diseases, including mesothelioma, lung cancer, and asbestosis. These conditions often take decades to develop after exposure. You should consider an asbestos inspection if:
- Your home was built before 1980. Older construction materials are far more likely to contain asbestos.
- You are planning a renovation. Drilling, cutting, or removing older materials can release fibers into the air.
- You have noticed damaged insulation, ceiling materials, or floor tiles. Deteriorating asbestos-containing materials pose a higher risk.
- You recently purchased an older home. A professional asbestos inspection gives you a clear picture of what you are working with.
You cannot identify asbestos by sight. Lab testing is required to confirm its presence.

Frequently Asked Questions
What is asbestos, and why is it dangerous in homes?
Asbestos is a naturally occurring mineral fiber used in home building materials throughout most of the 20th century. It becomes dangerous when its fibers are disturbed and released into the air. Inhaling these fibers over time can lead to serious lung diseases, including mesothelioma and asbestosis.
What homes are most likely to contain asbestos?
Homes built before 1980 carry the highest risk. Asbestos was commonly used in insulation, floor tiles, ceiling textures, drywall compound, roofing materials, and pipe wrap during that era. Even some homes built into the mid 1980s may contain asbestos if older materials were still in supply.
How do I know if my home has asbestos?
You cannot identify asbestos by visual inspection alone. A licensed asbestos inspector must collect material samples, which are then sent to an accredited laboratory for testing. This is the only reliable way to confirm the presence of asbestos-containing materials.
Is asbestos still used in home construction today?
Asbestos is no longer used in most residential building materials in the United States. The EPA has banned specific products and continues to pursue broader restrictions. However, asbestos still exists in millions of older homes and has not been completely eliminated from all imported materials.
When should I get an asbestos inspection?
An asbestos inspection is recommended before any renovation or demolition work in a home built before 1980. It is also advisable if you notice damaged insulation, crumbling ceiling materials, or deteriorating floor tiles. Asbestos testing is a critical step in protecting your household’s indoor air quality.
