root of the problem
The issue stems from a combination of building practices, materials and design trends that were common in Auckland in the 1990s and early 2000s:
- Monolithic cladding systems like stucco or fibre-cement without proper cavity systems
- Untreated timber framing that absorbs and retains moisture
- Poor flashing or detailing around windows, decks, and penetrations
- Minimal eaves, creating direct water exposure to walls
Over time, water makes its way behind the cladding and gets trapped, leading to rot, mould, and serious structural damage.
