I refer to the recent debate about unresolved water leakage issues between home owners (Water leakage a big issue among homes; May 11).
Home owners are indeed at the mercy of renovation contractors who pay scant attention to the quality of waterproofing works.
The Housing Board maintains a registry of renovation contractors and is in the best position to tackle this persistent problem.
The HDB can simply require all registered contractors to provide a five-year warranty against all inter-floor waterproofing leaks.
This will reduce overall maintenance issues as well as prevent disputes between neighbours.
