Asbestos was used in the construction and renovation of most Australian homes, especially during the building boom years of the last century. If your NSW property was built before 1990, there is a good chance it has asbestos-containing materials (ACMs).

Knowing the early warning signs could protect your family, your tenants, or your workers, before a renovation or demolition job puts everyone at risk. Read on to discover some of the signs of asbestos in a house and learn the ONLY way to confirm whether your home contains asbestos and the only safe asbestos removal methods for you and your family.

What Is Asbestos and Why Is It Still a Problem?

Asbestos was widely used in construction throughout Australia from the 1940s through to the late 1980s. It was valued for its fire resistance, durability, insulating properties and affordability.

The problem is that asbestos fibres, once disturbed, become airborne. Breathing in those fibres can cause serious and life-threatening diseases, including mesothelioma, asbestosis, and lung cancer. There is no safe level of asbestos exposure.

In NSW alone, an estimated 1 in 3 homes built or renovated between 1945 and 1990 contain some form of asbestos. That is why identifying the signs early matters so much.

How Do You Know if Your House Might Contain Asbestos?

There is no way to confirm the presence of asbestos by sight alone. The only definitive method is laboratory testing of a material sample by an accredited analyst. That said, there are several reliable indicators that should prompt you to stop work and seek a professional assessment.

When Was the House Built or Last Renovated?

The age of a property is the single most useful clue. If a home was built or significantly renovated between 1945 and 1990, there is a strong likelihood that asbestos-containing materials NSW were used somewhere in its construction.

  • Homes built between 1945 and 1987 carry the highest risk
  • Properties renovated during this period may also have ACMs added during the upgrade
  • Homes built after 1990 are generally lower risk, but some products remained on the market until a full ban was introduced in December 2003

If you are unsure of the build date, check your council records or a title search.

What Are the First Signs of Asbestos in a House?

The following material types and locations are the most common sources of asbestos in older Australian homes. Each one should be treated as a suspect until professionally tested.

Fibro (Fibre Cement) Wall Sheeting, Is Your Cladding Asbestos?

Fibro sheeting was one of the most common building materials in Australian homes from the 1950s through to the 1980s. It was used extensively for:

  • External wall cladding
  • Internal wall linings
  • Eaves and soffits
  • Garden sheds and garages
  • Fencing panels

Fibro sheeting containing asbestos is often grey in colour, smooth-faced, and installed in large flat sheets. Sheets that are cracked, crumbling, weathered, or showing surface deterioration are a serious concern, as damaged asbestos is far more likely to release fibres.

Corrugated Roofing, Could Your Roof Contain Asbestos?

Corrugated cement sheeting (commonly known as “Super Six” roofing) was widely used on Australian homes and outbuildings before 1990. This type of roofing often contains non-friable (bonded) asbestos, which is generally less hazardous when intact but becomes hazardous when drilled, cut, or broken.

Signs to look for:

  • Corrugated cement sheets on the roof or pergola cover
  • Cracked, broken, or moss-covered cement roofing sheets
  • Flaking or powdering material along roof edges or ridgelines

Ceiling Tiles and Textured Ceilings, What Does Asbestos Look Like Overhead?

Certain ceiling types in older homes pose a significant risk:

  • Flat fibro ceiling sheets, particularly in homes built before 1980
  • Textured or “popcorn” ceilings, which may have been sprayed with a friable asbestos-containing compound
  • Decorative pressed or tiled ceilings with paper or vinyl backing

Friable asbestos in ceilings is among the most dangerous, as any disturbance, even drilling a single hole, can release fibres directly into the living area.

Floor Tiles. Is There Asbestos Under Your Feet?

Vinyl floor tiles, particularly the 9-inch by 9-inch (225mm x 225mm) square tiles found in homes built before the 1980s, frequently contained asbestos. The asbestos fibres were bonded into the tile during manufacturing to add strength and heat resistance.

Watch for these signs:

  • Old vinyl or linoleum floor coverings that are lifting, cracking, or deteriorating
  • A second layer of tiles laid over the original, the original layer beneath may contain asbestos
  • Adhesive residue or “black mastic” under old tiles, which can also contain asbestos

Pipe Lagging and Thermal Insulation, Is Asbestos Hiding in Your Walls or Roof Void?

Insulation and pipe lagging are two of the most hazardous asbestos applications in older homes. Asbestos was commonly used to wrap hot water pipes, heating ducts, and boiler components because of its excellent heat resistance.

Common locations include:

  • Roof voids and subfloor spaces, particularly around old pipe runs
  • Around hot water systems and water pipes in older laundries and kitchens
  • Behind bathroom wall linings and under bath surrounds

This type of asbestos is often friable, meaning it can crumble easily and release fibres with minimal disturbance.

Eaves, Soffits, and Fascia Boards: Are the Edges of Your Roof a Risk?

The eaves are one of the most commonly overlooked asbestos locations in residential properties. In homes built before 1990, the soffit lining (the flat board under the roof overhang) was frequently made of asbestos-cement sheet.

Signs to check:

  • Flat or slightly ribbed sheet material under the eaves
  • Sheets with thick, visible joints or metal capping at the joins
  • Cracked, flaking, or deteriorating eave linings

What Are the Different Types of Asbestos Found in Homes?

Understanding the two main categories helps explain why some materials are more urgent than others.

Both types require professional assessment. Do not assume bonded asbestos is safe simply because it appears intact.

Can You Identify Asbestos Without a Professional?

No. Asbestos cannot be reliably identified by appearance alone. Fibres are microscopic and cannot be seen with the naked eye. Materials that look similar to asbestos cement may be asbestos-free, and materials that look perfectly ordinary may not be.

What you should never do:

  • Cut, drill, sand, or scrape any suspected ACM
  • Use a high-pressure hose on suspected materials
  • Break or disturb suspect materials to “get a better look”
  • Attempt DIY removal of any suspected asbestos

What you should do:

  • Don’t touch or disturb the material
  • If in doubt, assume any suspected material is asbestos until you have a professional to carry out asbestos testing
  • Contact a licensed asbestos assessor or removalist for a professional inspection and sample testing

What Should You Do if You Suspect Asbestos in Your Home?

If you have an older property and are planning any renovation, demolition, or building work, the following steps apply.

  1. Stop all work in the area immediately
  2. Clear the area of all people, particularly children
  3. Do not disturb, sweep, or vacuum the suspected material
  4. If the material is damaged and fibres may be airborne, dampen the area gently and cover with plastic sheeting
  5. Contact a licensed asbestos assessor to inspect and sample the material
  6. Wait for confirmed test results before resuming any work

Asbestos removal Central Coast, Newcastle should only be carried out by licensed asbestos removalists. Engaging an unlicensed contractor is illegal and can result in on-the-spot fines from SafeWork NSW.

Is Asbestos More Common in Certain Locations?

Asbestos in Central Coast and Newcastle Homes

The Central Coast and Newcastle regions have a large stock of older housing. Many properties in suburbs such as Gosford, Wyong, Tuggerah, Maitland, and Lake Macquarie were built during the peak period of asbestos use in Australia, between the late 1940s and 1980s.

This means:

  • A high proportion of fibro homes remain in these areas
  • Older weatherboard homes may have fibro cladding additions or outbuildings
  • Older industrial, commercial, and warehouse properties may also contain asbestos-containing materials

If you own or manage property in these regions, it is worth arranging a professional asbestos inspection before any renovation or demolition work begins.

Frequently Asked Questions About Asbestos in Homes

What does asbestos look like in walls?

Asbestos-containing wall sheeting typically appears as large, flat, grey sheets with a smooth or slightly textured surface. The sheets are usually fixed with nails and joined with a compound or metal strip. You cannot confirm the presence of asbestos by appearance alone, only laboratory testing is conclusive.

Is asbestos dangerous if it is not disturbed?

Intact, non-friable asbestos that is in good condition poses a lower immediate risk. However, any asbestos that is cracked, weathered, broken, or regularly disturbed must be assessed and managed by a professional.

How do I get asbestos tested in NSW?

Contact a licensed asbestos assessor to safely collect a sample. They will seal and label any suspect material and take it to an accredited laboratory for testing. Do not attempt to collect a sample yourself.

Can I remove asbestos myself in NSW?

In NSW, you can legally remove up to 10 square metres of non-friable (bonded) asbestos yourself, provided you follow SafeWork NSW guidelines. However, professional removal is strongly recommended in all cases to ensure compliance, safety, and proper disposal of asbestos waste. All friable asbestos must be removed by a licensed Class A asbestos removalist.
