Damaged aluminium facade panels can almost always be replaced individually without stripping the surrounding cladding. The process depends on the system - interlocking profiles like interloQ allow single-panel swaps with minimal disruption, while face-fixed element13 panels unbolt and replace directly. The key consideration is not the repair itself but colour matching between new and weathered panels.
What causes facade panel damage?
Facade damage on Australian buildings typically comes from vehicle impact at lower levels, severe weather, vandalism, and - most commonly - construction damage from other trades. Scaffolding strikes, dropped tools, and material impact during fit-out account for a significant portion of the panel replacements Valmond & Gibson supplies.
Aluminium facade systems are modular assemblies, so individual components can be accessed and replaced. The question is how easily the specific system allows it.
How do you replace an interloQ panel?
interloQ’s interlocking rainscreen design is a practical advantage for repair. Individual panels can be replaced without disturbing adjacent panels.
The process:
- Disengage the damaged panel - lift and slide to release the interlocking edge from the adjacent panel.
- Remove fixings - unscrew or unclip the panel from the subframe.
- Install the new panel - position, fix to subframe.
- Re-engage the interlock - slide the new panel into the adjacent panel’s interlock profile.
This is a significant advantage over many cladding systems where accessing one damaged panel requires stripping multiple surrounding panels to reach the fixings. With interloQ, one panel out, one panel in.
How do you replace an element13 panel?
For face-fixed element13 installations, the process is straightforward:
- Remove fasteners from the damaged panel.
- Remove the panel from the subframe.
- Install the replacement panel and re-fix.
For concealed-fix element13 installations, the fixing system may require temporary removal of one or two adjacent panels to access the concealed brackets. This is still a localised repair - you are not stripping back large sections of facade - but it does involve slightly more work than a face-fixed replacement.
What about colour matching?
Colour matching is the real consideration with any facade panel replacement.
If the original panels have been exposed to UV for several years, a brand-new replacement panel in the same colour code will look different. The surrounding panels will have faded slightly. The colour codes match, but the visual appearance does not - at least not immediately.
There are a few ways to manage this:
- Replace a section rather than a single panel. If the repair is in a prominent location, replacing a larger area (a full bay or a floor level) creates a consistent appearance across that zone.
- Use original-batch spares. If spare panels were ordered with the original supply and stored properly, they will have aged similarly to the installed panels and provide a much closer match.
- Accept a minor difference. In many cases, the colour difference between a new panel and a lightly weathered original is minor and will equalise over 12-18 months of UV exposure. This is often the pragmatic call for less visible areas.
Should you order spare panels at installation?
Yes. This is one of the simplest things a building manager or installer can do to make future repairs easier.
Order 2-5% spare panels at the time of original installation. Store them flat, covered, in a dry location out of direct sunlight. These spares age in storage at a rate closer to the installed panels than a brand-new production run years later.
Spares also eliminate lead time. A replacement panel from stored spares can be installed the same week. A new production order - particularly for colour-matched element13 panels with offshore lead times - can take 8-12 weeks.
When should you repair versus replace?
Not every mark on a facade requires a new panel:
- Minor surface scratches on powder coat can sometimes be addressed with colour-matched touch-up paint. The result will not be factory-perfect, but it prevents corrosion and is acceptable for less visible locations.
- Dents, deformation, or coating failure require panel replacement. Do not attempt to heat, bend, or reshape aluminium panels on site. The material work-hardens, the coating will crack, and the result will be worse than the original damage.
If in doubt, replace. A clean new panel is always a better long-term outcome than a patched repair that deteriorates.
How should you clean after a repair?
When replacing a damaged panel, clean the surrounding panels at the same time. Use mild detergent and warm water - nothing abrasive or solvent-based. This reduces the visual contrast between the new replacement and the weathered panels around it.
It is also a good opportunity to inspect adjacent panels and fixings for any issues not noticed during routine maintenance.
Can V&G supply individual replacement panels?
Yes. Valmond & Gibson can supply individual replacement panels in the same product, profile, and colour as the original installation. Contact the team with the original order reference for the fastest matching - this gives us the exact profile, colour code, and finish specification without guesswork.
For projects where the original order details are not available, a sample of the existing panel or a photo with colour reference can usually get us to the right match. Replacement panels are supplied through the same channels as the original order - typically through the installing contractor or facade subcontractor.
