Renovation work can turn a hidden asbestos issue into an urgent one. Before you start removing walls, replacing a bathroom or updating an old garage, take time to understand what materials may be present and how the work could disturb them.

This checklist helps NSW homeowners plan the first steps safely.

Check the age and history of the property

Older homes are more likely to contain asbestos-containing materials, especially where original fibro sheeting, eaves, ceilings, roofing, flooring or wet-area linings remain. Renovations completed decades ago can also contain asbestos products.

Property age is a useful clue, but it is not proof. Treat suspect materials carefully until they have been assessed.

Identify work that could disturb materials

Drilling, sanding, cutting, demolition, pressure-cleaning and removing old sheets can all disturb asbestos. Make a list of every part of the project that involves these activities, including work by electricians, plumbers, roofers and demolition contractors.

This helps you decide where an inspection is needed before trades arrive.

Arrange an assessment before demolition

A professional asbestos inspection can identify accessible materials of concern and recommend the next step. Where sampling is needed, it should be carried out by a competent person using controlled methods and analysed by a laboratory that can identify asbestos.

Do not ask a builder or handyman to take a piece home for testing. Breaking a suspect material to obtain a sample can create avoidable exposure.

Know when licensed removal is required

In NSW, a Class B asbestos removal licence is required for more than 10 square metres of non-friable asbestos. Friable asbestos removal requires a Class A licence, regardless of the amount. Do not start demolition until the material has been assessed and the appropriate licensed removal arrangements are in place.

Where licensed removal involves more than 10 square metres of non-friable asbestos, or any friable asbestos, the required clearance inspection and clearance certificate must be completed before the area is returned to normal use.

Keep the site controlled

Until you have a plan, avoid disturbing suspect materials and keep other people away from the area. Do not sweep or vacuum dust from a damaged sheet. Do not place suspect waste in a household bin.

If removal is required, use a licensed asbestos removal provider with the appropriate controls, PPE and waste procedures for the job. For work that requires a licence, the removalist must also give the regulator the required notice before work starts.

Coordinate your trades

Share the asbestos assessment outcome with the trades working on your project. Schedule removal before demolition, installation or finishing work. This avoids rework, delays and the risk of other contractors entering an uncontrolled area.

Conclusion

A safe renovation starts before the first tool is switched on. By identifying suspect materials, arranging an assessment and coordinating licensed removal where needed, you can protect your household and keep the project moving.
