The cost of ignoring it
Facade defects are the defects that fall on people. A drummy render panel or corroded lintel is a public-safety liability the moment it lets go — and an emergency make-safe at 2am costs multiples of a planned repair.
The defect, plainly
Facades fail at interfaces: render debonding from substrate, corroding steel lintels and shelf angles cracking the masonry above, precast joints losing their seal, fixings rusting behind cladding. Gravity turns every one of these into a public-safety issue — which is why facade remediation is as much risk management as building work.
Diagnostic approach
- Close-range visual survey — rope access or EWP, every elevation, defects tagged to a numbered schedule with photographs
- Drummy-area mapping by tap testing, quantified per elevation (this is what makes the scope priceable)
- Targeted break-outs at representative defects to confirm cause — corroded lintel vs. failed render bond vs. substrate cracking are three different repairs
- Fixing and anchor checks where panels or attachments are suspect
- Drone survey for whole-of-facade context and inaccessible elements, annotated against the defect schedule
Repair methodology
Scope is grouped by defect class, each with a specified system: cut-out-and-reinstate render repairs with matched finishes; lintel replacement or cathodic treatment; repointing in analysed mortar; joint reinstatement with correctly sized backer and sealant; whole-of-elevation protective coating where carbonation or water ingress is the driver.
Access is engineered per elevation — rope access for distributed low-density defects, EWP for mid-rise reachable zones, scaffold only where repair density justifies it. The comparison is shown in the scope so the committee can see why.

Interwar and postwar masonry apartment buildings, 1970s–90s rendered facades, precast commercial buildings, and mixed heritage streetscapes across inner Melbourne.
