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 its link to NZ's leaky homes crisis. These properties can trap moisture, causing rot and potential health issues.
Key risks include:
- High repair costs, often exceeding $330,000
- Difficulty securing finance and insurance
Before purchasing, look for warning signs like mould or sagging ceilings. Always get a specialised building inspection to assess watertightness, especially for homes built between 1987 and 2005, to understand the full investment required.
