An old garage can look like just another renovation project, until you discover asbestos. Many older garages across Sydney were constructed using asbestos-containing materials, particularly fibro cement sheets used for walls, ceilings, roofing and eaves.
If you are planning to renovate, demolish or replace an older garage, identifying asbestos before work begins is essential. Asbestos garage removal is not a job that should be treated like ordinary building waste. Damaging asbestos materials can release hazardous fibres, creating unnecessary risks for workers, residents and surrounding areas.
Here is what Sydney homeowners should know before starting an asbestos garage removal project.
Why Is Asbestos Commonly Found in Sydney’s Older Garages?
Asbestos was widely used in Australian construction because it was durable, affordable and resistant to heat and fire. It could be incorporated into cement products to create strong, lightweight building materials.
In older garages, asbestos may be found in:
- Corrugated roof sheets
- Fibro wall panels
- Ceiling sheets
- Eaves and soffits
- Garage cladding
- Fencing around the garage
- Cement-based panels
- Some insulation and other building components
The presence of asbestos cannot always be confirmed simply by looking at a material. Some asbestos-containing products can resemble ordinary cement sheeting.
Why Is Garage Asbestos Removal Important?
The biggest concern is the potential release of airborne asbestos fibres when asbestos-containing materials are cut, drilled, broken, sanded or otherwise disturbed.
A garage demolition or renovation can involve activities that potentially damage building materials. Attempting to remove asbestos without appropriate knowledge, equipment and procedures can therefore increase the risk of fibre release.
Even if asbestos appears intact, homeowners should avoid disturbing it unnecessarily.
Start With an Asbestos Inspection
Before removing an older garage, consider having suspected materials assessed by a suitably qualified asbestos professional.
An inspection can help identify materials that may contain asbestos and determine what needs to happen before renovation or demolition begins.
Where necessary, samples may be taken for laboratory analysis. Do not take samples yourself unless you have the appropriate training and controls to do so safely.
Identifying asbestos before work starts can also help you plan the project more effectively and avoid unexpected delays.
Asbestos Removal Should Be Properly Planned
Once asbestos has been identified, removal should be planned according to the type, condition and quantity of asbestos-containing material involved.
The appropriate approach can depend on factors such as whether the material is bonded or friable, its condition, the location of the garage and the scope of the work.
For homeowners, one of the most important decisions is choosing an appropriately qualified and experienced asbestos removal contractor.
Ask the contractor about their relevant licence, experience, removal procedures, waste handling and disposal arrangements before work begins.
What Happens During Garage Asbestos Removal?
The exact process will vary depending on the garage and the asbestos materials involved. Generally, professional removal involves controlling the work area, using appropriate protective equipment and carefully removing materials to minimise the chance of fibre release.
The removed asbestos waste must also be handled, contained, transported and disposed of appropriately.
This is particularly important because asbestos waste should not simply be placed in a normal household or construction rubbish bin.
A professional contractor can explain the controls that will be used and what happens to the asbestos waste after removal.
What About Garage Demolition?
If the entire garage is being demolished, asbestos should be considered before demolition begins.
Demolishing an asbestos-containing structure without proper planning can damage asbestos materials and potentially spread contamination throughout the work area.
Where asbestos is present, it may need to be removed before the remaining structure is demolished. The requirements can vary depending on the circumstances and the type and quantity of asbestos involved.
This is one reason why an asbestos assessment should be part of planning an older garage renovation or demolition.
Don’t Forget the Surrounding Area
Asbestos garage removal is not only about the building itself. Nearby soil, gardens, pathways, fences and other structures may also need consideration if asbestos-containing materials have previously been damaged or improperly disposed of.
If you suspect an old garage has already been damaged, avoid disturbing debris and seek professional advice about assessment and cleanup.
Keeping children, pets and other people away from a potentially contaminated work area is also an important precaution.
Choosing an Asbestos Removal Professional in Sydney
When comparing asbestos removal companies in Sydney, don’t choose solely on price. Ask whether the contractor has experience with garage removals and understands the relevant NSW requirements.
You can also ask for information about:
- Relevant asbestos removal licensing
- Insurance
- Previous experience
- Proposed removal methods
- Waste disposal arrangements
- Site safety procedures
- Required documentation
- Whether clearance procedures will be provided where applicable
A professional approach can make the project safer and help prevent problems later.
What Sydney Homeowners Should Remember
If your garage was built or renovated during a period when asbestos-containing building products were commonly used, don’t assume the materials are asbestos-free.
Before renovation or demolition, have suspected materials properly assessed. If asbestos is confirmed, use an appropriately qualified professional for removal where required and ensure the waste is handled and disposed of correctly.
The cheapest-looking approach can become much more expensive if asbestos is accidentally damaged or spread during a renovation. Planning the removal properly from the beginning can help protect your household, workers and neighbours while keeping your garage project on track.
For Sydney homeowners, the key message is simple: identify asbestos first, plan the work carefully and use the right professionals for removal and disposal.
