Water seepage in building is generally caused by defective fabric or installations of buildings and the lack of proper maintenance. As such, it is the responsibility of the owners to maintain and manage their buildings.

In case there is water seepage which you suspect is coming from the flat on the upper floor or next door, you should approach the neighbors concerned for investigation and repair works. Assistance may be sought from the management firm or the Owners' Corporation of your building. With the help of a building professional or legal consultant, you may also request the person causing the water seepage to rectify the problem in accordance with the Deed of Mutual Covenant, or lodge a claim for damages.
