Renovating an older home can uncover materials you were not expecting. Before drilling, cutting, sanding or demolishing, it is important to consider whether asbestos-containing materials may be present. In NSW, the safest approach is to pause work on suspect materials and arrange a professional assessment.

Why testing matters before work begins

Asbestos fibres can become airborne when asbestos-containing materials are damaged or disturbed. That means a small renovation task, such as removing a wall sheet, replacing flooring or updating a bathroom, can create a bigger safety issue if the material has not been identified first.

You cannot confirm asbestos by appearance alone. Fibro sheeting, vinyl tiles, eaves, roofing and backing boards can look similar to non-asbestos products. Testing provides a clear answer so you can plan the work properly.

Areas that deserve extra care

Homes built or renovated before the mid-1980s may contain asbestos in several locations. Common examples include external cladding, eaves, ceilings, wet-area wall linings, garages, sheds, fences, flues and some floor coverings.

Pay particular attention before work in bathrooms, kitchens, laundries, roofs and garages. These areas often involve cutting, drilling or removal work that can disturb older building materials.

What a professional assessment involves

A trained assessor reviews accessible materials, their condition and the work you are planning. Where sampling is appropriate, it is carried out by a competent person using controlled methods and sent for laboratory analysis. The result helps determine whether the material can remain in place, needs management controls or should be removed.

Do not take a sample yourself. Breaking, snapping or scraping a suspect material can release fibres and create contamination that was not there before.

What to do while you wait

Keep the area undisturbed. Avoid sweeping, vacuuming, pressure-cleaning or using power tools nearby. If practical, keep children, pets and other trades away from the immediate area until you have advice.

If a material has already been damaged, do not attempt a DIY clean-up. A licensed asbestos professional can advise on the next safe step.

Plan your renovation with confidence

Testing before renovation is a practical way to protect your household, trades and project timeline. Once you know what is present, you can make informed decisions about removal, controls and scheduling.

If removal is needed, NSW licensing requirements apply: more than 10 square metres of non-friable asbestos requires a Class B asbestos removal licence, while friable asbestos removal requires a Class A licence. For the licensed removal of more than 10 square metres of non-friable asbestos, or for any friable asbestos removal, the required clearance inspection and clearance certificate must be completed before the area is returned to normal use.

Conclusion

The right time to think about asbestos is before the first cut or drill hole. A professional assessment gives you the information needed to move forward safely and avoid unnecessary exposure.
