Where Does Facade Remediation Stand in 2026?
Australia’s combustible cladding remediation effort is now nearly a decade into its lifecycle, and the work is far from finished. State government programs in Victoria, New South Wales, Queensland, and the ACT have collectively addressed several hundred high-risk buildings, but thousands of buildings remain in various stages of assessment, design, and active rectification. For building owners who have not yet started - or who are partway through the process - the questions are practical: what does this actually involve, what does it cost, and how long does it take?
The short answer is that remediation timelines and costs vary significantly depending on the building, but the general process is well established and repeatable. The longer answer is worth understanding, because decisions made early in the process have a direct impact on time, cost, and outcome.
How Did We Get Here?
The national cladding audit programs were triggered by a series of high-profile fire events - the 2014 Lacrosse fire in Melbourne, the 2017 Grenfell Tower tragedy in London, and the 2019 Neo200 fire, also in Melbourne. These events exposed the widespread use of combustible aluminium composite panels (ACPs) with polyethylene cores in applications where the National Construction Code required non-combustible materials.
State governments responded with audit and remediation programs. Victoria’s Cladding Safety Victoria has overseen rectification of more than 360 buildings. NSW’s Project Remediate provides interest-free loans for eligible residential buildings. Queensland’s Safer Buildings program placed the cost burden on building owners. The ACT has largely completed government building remediation.
What remains is a substantial tail of buildings in the lower-risk categories, privately funded projects, and buildings that have been assessed but not yet scheduled for work. The pipeline will continue to generate remediation projects well into the late 2020s.
What Does the Remediation Process Actually Look Like?
The process follows a consistent sequence, regardless of the state program involved.
1. Facade audit and risk assessment
A qualified facade assessor inspects the building’s external cladding and provides a report identifying what materials are present, where combustible cladding exists, and the level of risk. In most jurisdictions, this assessment determines whether the building enters a formal remediation pathway. For buildings in government programs, the audit is often funded or subsidised. For privately funded projects, this cost falls to the owners corporation.
2. Scope development and design
A facade engineer or building consultant develops the remediation scope - what gets removed, what replaces it, and how the new system integrates with the existing building structure. This stage is critical. Decisions about replacement materials, fixing systems, and weatherproofing details are made here, and they directly affect both cost and program.
Good scope development considers the existing substructure. If the original framing can support the replacement material without modification, that reduces both cost and installation time. If structural upgrades are needed, the program extends.
3. Supply and procurement
Once the scope is finalised and a contractor is engaged, materials are procured. For remediation projects, the replacement material must be non-combustible and tested to AS 1530.1. The practical reality is that most remediation projects in Australia use solid aluminium panels - the product that has become the industry standard for ACP replacement.
Lead times vary by product and colour. Stock colours in standard sheet sizes can ship within days. Non-stock colours or custom dimensions require manufacturing lead times, typically 8 to 12 weeks for overseas production. Specifying early and confirming colour selections before tender close avoids unnecessary delays.
4. Removal and installation
The existing combustible cladding is removed, typically in a staged sequence that allows the building to remain occupied. Scaffolding or swing-stage access is erected, combustible panels are stripped, and the new cladding system is installed. Most remediation contractors work floor by floor or elevation by elevation.
Installation speed depends on the replacement system and the condition of the existing substructure. A straightforward panel-for-panel replacement on a sound framing system can move quickly. Where the original framing needs reinforcement or replacement, the work slows accordingly.
5. Certification and compliance sign-off
Once installation is complete, the building surveyor or certifier inspects the work and issues the relevant compliance documentation. This closes out the building’s remediation requirement under the applicable state program. For buildings in government-funded schemes, this step also triggers final milestone payments.
Why Is Solid Aluminium the Standard Replacement Material?
Several factors have made 3mm solid aluminium panels the default choice for ACP remediation in Australia.
Non-combustible performance. Solid aluminium is non-combustible when tested to AS 1530.1. There is no core material to burn - the panel is aluminium all the way through. This eliminates the fundamental risk that triggered the remediation programs in the first place.
Dimensional compatibility. Solid aluminium panels are available in sheet sizes that closely match the original ACP panels being removed. In many cases, the replacement panels can be cut and fixed to the existing substructure with minimal modification. This is a significant practical advantage on remediation projects, where the goal is to replace the cladding without redesigning the entire facade system.
Established supply chain. Solid aluminium panels are available in a wide range of colours, including PVDF-coated finishes that match the aesthetic of the original building. Stock colours are held in Australian warehouses for fast turnaround. The supply chain is mature and well understood by remediation contractors.
Coating durability. PVDF paint finishes on solid aluminium panels offer strong UV resistance, corrosion resistance, and colour retention - important characteristics for a material that needs to perform for decades after installation.
element13 by Valmond & Gibson is a 3mm solid aluminium panel system that has been used extensively across Australian remediation projects. It is CSIRO tested as non-combustible to AS 1530.1, available in more than 30 standard colours, and carried in stock at V&G’s Sydney warehouse.
What Drives Remediation Costs?
Building owners regularly ask what remediation will cost, and the honest answer is that it varies widely. The main cost drivers are:
- Building height and access complexity. Taller buildings require more extensive scaffolding or access systems, which can represent a significant portion of the total cost.
- Substructure condition. If the existing framing behind the cladding is in good condition, the replacement is more straightforward. If corrosion, water damage, or structural inadequacy is found during strip-out, remediation costs increase.
- Colour and finish selections. Stock colours are cheaper and faster. Custom colours or non-standard finishes add cost and lead time.
- Building occupation. Working on an occupied building introduces access constraints, noise limitations, and staging requirements that affect program and cost.
- Scope of remediation. Some buildings require full facade replacement. Others need only specific elevations or sections addressed. The scope of work is the single biggest variable.
As a general guide, remediation costs for mid-rise residential buildings in government programs have ranged from several hundred thousand dollars to several million, depending on the factors above. Privately funded projects outside government schemes can be higher, as they do not benefit from subsidised assessment or project management.
What Should Building Owners Do Now?
If your building has not yet been assessed, or if an assessment has identified combustible cladding, the most productive step is to engage a qualified facade consultant to develop a clear remediation scope. Early decisions about replacement materials, fixing methods, and colour selections directly reduce the risk of delays and cost overruns once construction begins.
For buildings entering the procurement phase, confirming material availability and lead times before engaging a contractor avoids the situation where a project is ready to start but materials are weeks away. This is particularly relevant for non-stock colours or large-area projects where supply needs to be coordinated.
The remediation pipeline in Australia is long, the work is complex, and every building is different. But the process is well established, the materials are proven, and the supply chain is mature. The buildings that move through remediation most efficiently are the ones where the scope is clear, the materials are confirmed early, and the project team understands the sequence.
