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 monolithic cladding house in NZ requires caution due to the leaky homes crisis, primarily affecting homes built between 1987 and 2005. While not all plaster homes leak, the risk is significant.
Warning signs include:
- Mould or fungi
- Sagging ceilings
- Swollen skirting boards
A specialised building inspection is crucial, as repairs can exceed $330,000. Homes built after 2005 with a proper drainage cavity are generally considered a lower-risk purchase.
