KUALA LUMPUR: Buying a new home does not always mean leaving construction defects behind, with recurring waterproofing problems potentially costing homeowners thousands of ringgit after the developer's Defect Liability Period (DLP) expires.

A survey by the National House Buyers Association (HBA) and Nippon Paint Malaysia found that nearly nine in 10 homeowners whose DLP had ended reported waterproofing problems afterwards, raising concerns over the long-term quality of homes and the financial burden of rectifying defects.

Among affected homeowners, 42.4 per cent spent at least RM5,001 on waterproofing repairs, including 14.2 per cent who paid more than RM10,000.

The findings highlight how defects that emerge or recur after the DLP can leave homeowners facing repeated repair costs, disruption and uncertainty over whether the underlying problem has been properly resolved.
