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 carries risks due to New Zealand's leaky homes crisis. Properties built between 1987-2005 are particularly susceptible, as design flaws can trap moisture, leading to structural rot and health issues.
Watch for warning signs like mould, sagging ceilings, and swollen materials. Repairs can exceed $330,000, and securing insurance can be difficult. Always get a specialised building inspection to assess watertightness before making an offer on a plaster-clad home.
