What Is Asbestos and Why Is It Dangerous?

July 9, 2026   •   8 min read   •   By Ana Margret

Asbestos was once considered a miracle material in the construction industry because of its strength, heat resistance, and insulating properties. For decades, it was widely used in homes, schools, factories, and commercial buildings throughout New York and across the United States. However, scientific research later revealed that asbestos exposure can lead to serious and potentially fatal health conditions. Today, property owners are encouraged to seek asbestos removal services whenever asbestos-containing materials become damaged or are disturbed during renovation or demolition projects.

If you own an older property, understanding what asbestos is and why it is dangerous is essential. Working with a qualified asbestos removal company can help you identify risks and protect the health of everyone who enters the building.

What Is Asbestos?

Asbestos is a naturally occurring mineral made up of microscopic fibers. Because these fibers are strong, flexible, and resistant to heat, asbestos was commonly added to many building materials throughout the 20th century.

Common types of asbestos include:

  • Chrysotile (White Asbestos) – the most commonly used type.
  • Amosite (Brown Asbestos) – frequently found in insulation products.
  • Crocidolite (Blue Asbestos) – known for its extremely fine and hazardous fibers.

Although these types differ in appearance and composition, all forms of asbestos can be harmful when fibers become airborne and are inhaled.

Where Is Asbestos Commonly Found?

Many older buildings still contain asbestos in a variety of materials. Homeowners are often surprised to learn that asbestos may be hidden behind walls, under flooring, or inside insulation.

Common locations include:

  • Pipe insulation
  • Boiler insulation
  • Vinyl floor tiles
  • Ceiling tiles
  • Roofing shingles
  • Cement siding
  • Popcorn ceilings
  • Drywall joint compound
  • HVAC duct insulation
  • Fireproofing materials

Because asbestos fibers are microscopic, you cannot determine whether a material contains asbestos simply by looking at it. Professional testing is the only reliable way to confirm its presence.

Why Is Asbestos Dangerous?

The primary danger comes from airborne asbestos fibers. When asbestos-containing materials are cut, drilled, sanded, broken, or allowed to deteriorate, tiny fibers can be released into the air. These fibers are so small that they can remain suspended for long periods and be inhaled without notice.

Once inhaled, asbestos fibers may become trapped in the lungs and remain there for decades. Over time, they can cause inflammation, scarring, and cellular damage that may lead to severe disease.

Health Risks Associated With Asbestos Exposure

1. Asbestosis

Asbestosis is a chronic lung disease caused by prolonged asbestos exposure. It results in scarring of lung tissue, making breathing increasingly difficult.

Common symptoms include:

  • Shortness of breath
  • Persistent cough
  • Chest tightness
  • Fatigue

Unfortunately, there is no cure for asbestosis.

2. Lung Cancer

Long-term exposure to asbestos significantly increases the risk of lung cancer, particularly for smokers. The risk increases with both the duration and intensity of exposure.

3. Mesothelioma

Mesothelioma is a rare but aggressive cancer that is strongly linked to asbestos exposure. It affects the lining around the lungs, abdomen, or heart and often develops decades after exposure.

When Does Asbestos Become Hazardous?

Many asbestos-containing materials are not immediately dangerous if they remain intact and undisturbed. The risk increases when materials become:

  • Broken
  • Cracked
  • Water damaged
  • Drilled or cut
  • Sanded
  • Demolished
  • Disturbed during remodeling

Before beginning any renovation project in an older building, property owners should consider professional inspection and testing.

Why DIY Asbestos Removal Is Risky

Attempting to remove asbestos yourself can create a much larger hazard. Without proper containment, fibers can spread throughout the property and contaminate additional areas.

DIY removal may lead to:

  • Widespread airborne contamination
  • Increased health risks
  • Improper disposal of hazardous materials
  • Potential violations of safety regulations

For this reason, experts recommend hiring a qualified asbestos removal company rather than attempting removal on your own.

How Professional Asbestos Removal Works

Removing asbestos is not a standard construction task. It requires specialized knowledge, protective equipment, and strict adherence to environmental and safety regulations. That’s why hiring professional asbestos removal experts is the safest approach for both residential and commercial properties.

A reputable asbestos removal company follows a systematic process to minimize the risk of exposure.

1. Property Inspection

The first step is a thorough inspection of the property. Certified professionals identify materials that may contain asbestos and determine whether laboratory testing is required. This assessment helps develop the safest removal strategy.

2. Laboratory Testing

Suspected materials are carefully sampled and sent to accredited laboratories for analysis. Testing confirms whether asbestos is present and identifies the type and concentration of fibers.

3. Risk Assessment

Once the results are available, professionals evaluate the condition of the material. In some cases, asbestos may be safely encapsulated if it is undamaged. In other situations, complete removal is the safest solution.

4. Containment

Before work begins, the affected area is completely sealed using heavy-duty plastic barriers and negative air pressure systems. This prevents asbestos fibers from spreading to other areas of the property.

5. Safe Removal

During the removal process, technicians wear specialized personal protective equipment (PPE) and use industry-approved techniques to carefully remove asbestos-containing materials while minimizing airborne dust.

6. Disposal

Asbestos waste cannot be thrown away with regular construction debris. It must be sealed, labeled, transported, and disposed of at approved hazardous waste facilities in accordance with federal, state, and local regulations.

7. Final Cleaning and Clearance

After removal, the work area is thoroughly cleaned using HEPA-filtered vacuums and specialized cleaning methods. Many projects also require air quality testing or clearance inspections before the area can be safely reoccupied.

This detailed process is why professional asbestos removal should always be handled by trained specialists rather than general contractors.

Why Hiring an Asbestos Removal Company Matters

Choosing an experienced asbestos removal company is one of the most important decisions you can make when asbestos is discovered on your property.

Qualified professionals have the training, certifications, and equipment needed to complete the project safely while protecting occupants, neighboring properties, and the environment.

An experienced contractor will:

  • Perform accurate inspections and testing
  • Follow OSHA, EPA, and New York regulations
  • Use proper containment methods
  • Prevent cross-contamination
  • Dispose of asbestos legally
  • Restore the work area safely

Attempting to save money by hiring an unqualified contractor or performing the work yourself can lead to costly contamination, legal issues, and serious health risks.

Signs Your Property May Contain Asbestos

Although asbestos cannot be identified by sight alone, certain factors increase the likelihood that your property contains asbestos-containing materials.

Your building may contain asbestos if:

  • It was built before the 1980s.
  • It still has its original flooring.
  • Pipe insulation appears aged or damaged.
  • Ceiling tiles have never been replaced.
  • Roofing materials are several decades old.
  • Cement siding is still intact.
  • Popcorn ceilings have not been renovated.
  • Old boiler or furnace insulation remains in place.

If any of these conditions apply to your property, avoid disturbing the material until it has been inspected by professionals.

Asbestos Risks for New York Property Owners

New York has a large number of older residential buildings, apartment complexes, schools, office buildings, and industrial facilities that were constructed when asbestos was widely used.

Renovation projects, aging infrastructure, water damage, and deterioration can all increase the likelihood of asbestos fibers being released into the air.

Whether you’re remodeling a home, renovating a commercial building, or preparing for demolition, scheduling an asbestos inspection before work begins is a critical step toward protecting workers, occupants, and the surrounding community.
