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 is risky due to the NZ leaky homes crisis, but not all plaster homes leak. Issues stemmed from poor design and construction between 1987-2005, trapping moisture and causing rot.
Be vigilant for warning signs:
- Mould or fungi
- Sagging ceilings
- Swollen materials
Repairs are costly, often exceeding $330,000, and can affect insurance. Before buying, a specialised building inspection focusing on moisture is essential to assess the risk and potential costs involved.
