Why Did Builders Use Asbestos in Construction?

Asbestos was a popular building material due to its abundance, affordability, and unique properties. Here’s why builders used asbestos in renovations and construction:

  • Durability: Asbestos is incredibly long-lasting. It’s resistant to wear and tear, which made it perfect for parts of the home that experience a lot of use or could be damaged, like floor tiles and roofing.
  • Fire resistance: Asbestos is non-flammable, which made it highly desirable in construction. Builders used asbestos in insulation, fire doors, and around pipes and boilers to prevent fires from spreading.
  • Insulation properties: Asbestos has excellent insulation properties. It was used to insulate homes against cold weather and noise. It was also used around pipes and boilers to prevent heat loss.
  • Chemical resistance: Asbestos is resistant to most chemicals, meaning it won’t degrade when exposed to cleaning products or other household chemicals.
  • Strength: When mixed with other materials, like cement or plastic, asbestos adds strength without adding much weight. This was useful in a variety of applications, including panels, siding, and even window frames.

However, it wasn’t until years later that the serious health risks associated with asbestos became widely recognized. Today, asbestos use is heavily regulated due to the danger it poses when its fibers are inhaled. Despite its practical properties, the health risks far outweigh the benefits of using asbestos in renovations and construction.

Why Asbestos Is a Problem

When left untouched, asbestos isn’t typically harmful. The problem arises when renovation work disturbs asbestos-containing materials, releasing fibers into the air. If inhaled, these fibers can lead to severe health issues, such as lung cancer, mesothelioma, and asbestosis.

How to Identify Asbestos

Identifying asbestos isn’t a job for the untrained eye. Its fibers are microscopic and can’t be seen, smelled, or tasted. Before starting renovation work on an older property, it’s recommended to hire a professional for an asbestos survey. It’s better to be safe than sorry.

What is Asbestos Testing?

Asbestos testing involves inspecting a building and collecting samples of materials suspected of containing asbestos, which are then analyzed in a laboratory to confirm the presence and type of asbestos.

How Is It Conducted?

Asbestos testing should always be conducted by a trained and certified professional. These professionals know where to look for asbestos, what precautions to take to prevent fiber release during the sampling process, and how to properly collect and handle samples to ensure reliable test results.

The process usually involves the following steps:

  1. Visual inspection: The professional will perform a thorough inspection of the property, looking for potential asbestos-containing materials.
  2. Sampling: If any materials are suspected of containing asbestos, small samples will be collected. During sampling, precautions are taken to prevent asbestos fibers from being released into the air.
  3. Laboratory analysis: The collected samples are sent to a laboratory, where they are analyzed using microscopy techniques, typically polarized light microscopy (PLM) or transmission electron microscopy (TEM).
  4. Report: After the laboratory analysis, the professional will provide a report detailing the findings, including the locations and types of asbestos found, if any.

When Should You Test for Asbestos?

Asbestos testing is typically recommended in the following situations:

  1. Before buying an older home: If you’re considering buying a home built before 1980, it’s wise to have it tested for asbestos.
  2. Before renovations: If you plan to renovate an older property, you should have it tested for asbestos before starting any work that could disturb asbestos-containing materials.
  3. If materials are damaged: If you notice damaged building materials in your home, such as cracked floor tiles, crumbling drywall, or deteriorating insulation, it’s a good idea to have them tested for asbestos.

Remember, if asbestos is properly encapsulated and not disturbed, it generally won’t pose a health risk. The problem arises when asbestos-containing materials are disturbed or damaged, allowing asbestos fibers to become airborne where they can be inhaled.

Where Are you Most Likely to Find Asbestos in an Older Home?

In older homes, particularly those built before 1980, asbestos can be found in several locations due to its versatile nature and various applications in construction. Here’s where you’re most likely to find asbestos:

  • Insulation: Asbestos was commonly used in insulation materials. It can be found in attic insulation, around pipes, and in heating systems.
  • Flooring: Asbestos was used in vinyl tiles, the backing on vinyl sheet flooring, and the adhesives used for installing floor tiles.
  • Ceiling tiles: Some types of ceiling tiles, particularly acoustic tiles, contained asbestos, as did some textured paints used for popcorn ceilings.
  • Roofing and siding: Many roofing materials, like shingles, felt, flashing, and cement, contained asbestos due to its durability and fire-resistant properties. Asbestos cement was also used in siding materials.
  • Pipe and duct coverings: Pipes in older homes, especially those for hot water and steam, may be covered with an asbestos blanket or tape.
  • Wall and ceiling compounds: Asbestos was used in some patching compounds and textured paints for walls and ceilings.
  • Heat-resistant fabrics and materials: Asbestos was often used in heat-resistant fabrics, such as around fireplaces.
  • Electrical wiring: Asbestos insulation was used around electrical wires due to its fire-resistant properties.

Remember, the presence of asbestos in these materials doesn’t pose a health risk unless the material is damaged or disturbed, releasing the asbestos fibers into the air. Always have a professional handle asbestos-containing materials to prevent exposure to harmful asbestos fibers.

Asbestos Removal

Proper Asbestos Handling and Removal

If asbestos is found, don’t panic. You’ll need to hire a licensed asbestos abatement professional to remove or encapsulate the materials. They’ll have the necessary training, experience, and equipment to manage the job safely and according to state and federal regulations.

Resources for Managing Asbestos Issues

There are numerous resources available, both online and offline, to help you navigate the complexities of asbestos management. Local health departments, the Environmental Protection Agency, and the Occupational Safety and Health Administration all provide guidelines and regulations regarding asbestos.

What Not to Do if You Find Asbestos

Stumbling upon asbestos during a renovation can be unsettling, but knowing what not to do is just as important as knowing what actions to take. Here’s a list of actions you should avoid if you encounter asbestos.

Don’t Disturb the Material

The health risks associated with asbestos arise when the fibers become airborne and are inhaled. Therefore, if you suspect a material contains asbestos, don’t disturb it. This means no drilling, cutting, sawing, sanding, or even brushing the material.
