Where You Might Find Asbestos in Your Home and What to Do About It

Asbestos-containing materials may still exist in certain areas if your home was built before the 1980s. Asbestos was commonly used in construction due to its fire-resistant and insulating properties, but it is now known to be a severe health hazard. ACM Services, Inc. is here to help guide you through where asbestos might be hiding in your home and the steps to take if you suspect it’s there.

Where Asbestos Might Be Found in Homes

1. Insulation:

• • Attic Insulation: Older homes may have asbestos-containing vermiculite insulation, which often looks like small pebbles that can fall and contaminate inner wall cavities.

• • Pipe Insulation: Asbestos wraps were used around pipes to prevent heat loss, especially in basements, crawlspaces, and pipe chases along exterior perimeter.

• • Duct Insulation: Often found wrapped around heating and cooling ducts in older homes and buildings, where it was commonly used for its heat-resistant and insulating properties.

• • Boiler and Furnace Insulation: These systems, often located in basements or utility rooms, were commonly insulated with asbestos.

2. Roofing and Siding:

• • Roof Shingles and Tar: Asbestos was frequently added to roofing materials due to its bonding qualities for durability.

• • Cement Siding Shingles: Homes built or renovated during the mid-1900s may have cement siding that contains asbestos fibers.

3. Flooring:

• • Vinyl Asbestos Tiles (VAT) and Sheet Flooring: Due to its high bonding and durability strength, asbestos was often used in vinyl tiles and their adhesives, making it a common material in older homes and buildings. It is particularly found in 9×9″ tiles but also in 12×12″ tiles and sheet flooring.

• • Older Linoleum or Laminate Flooring: If your flooring dates back several decades, it may contain asbestos in both the surface and backing.

• • Mastic / Adhesive: Commonly used in older buildings to secure tiles and other flooring materials, offering durability and bonding but posing a risk when disturbed during renovations or demolition.

• • Wood Parquet Mastic: Parquet flooring is commonly found in older homes, particularly in living rooms, dining rooms, and hallways. The adhesive used in the flooring was asbestos, which provided strength and bonding.

4. Walls and Ceilings:

• • Popcorn Ceilings: This popular textured ceiling style, used from the 1950s to 1980s, often contained asbestos.

• • Drywall Joint Compound: The substance used to seal seams between drywall panels in older homes could also contain asbestos.

• • Wall and Ceiling Plaster: Certain textured ceiling plasters use asbestos to enhance durability and safety.

• • Textured Ceiling Plaster: Asbestos is used as a bonding agent for this decorative plaster throughout homes and buildings.

• • Ceiling Tiles: Often found in basements, kitchens, or acoustic drop ceilings, where asbestos was used to enhance fire resistance and soundproofing qualities.

5. Other Areas:

• • Fireplaces: Heat-resistant materials like asbestos millboards were used around fireplaces and hearths.

• • Window Caulking & Glazing: Some older caulking materials used around windows and doorframes contained asbestos to improve durability and prevent leaks.
