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 NZ's leaky homes crisis, but not all are leaky. Issues from 1987-2005 were caused by poor building practices that trapped water, leading to rot.
Watch for warning signs like mould, sagging ceilings, or swollen materials. Repairs can exceed $330,000, and securing finance or insurance is often difficult. Before purchasing, a specialised building inspection focusing on moisture is essential to assess the risk.
