Should I buy a monolithic cladding house? Understanding NZ leaky homes
Properties with plaster or monolithic cladding can be risky purchases, but they're not all leaky.

AI summary
Buying a home with monolithic cladding requires caution due to the NZ leaky homes crisis, but not all are problematic. Issues often stem from homes built between 1987-2005 with poor design and no drainage cavity.
Warning signs include:
- Sagging ceilings
- Mould or fungi
- Swollen skirting boards
Repairs can exceed $330,000, and securing finance or insurance can be difficult. A specialised building inspection is essential to assess moisture levels and risk before you commit.
