There are numerous causes for ceiling leakage. In most
cases, it is leakage of the drainage pipe of a flat that
causes ceiling leakage to the flat directly below.
The occupant of the affected flat should engage a
licensed plumber
to carry out a thorough examination. If necessary, the
occupant of the upper flat should be asked to provide
access for conducting tests.
If drainage seepage is suspected to be the cause for
ceiling leakage, the occupant of the affected flat may
seek assistance from the Food and Environmental Hygiene
Department (Hotline no. 2868 0000).
If water mains seepage is suspected to be the cause
for ceiling leakage, the occupant of the affected flat
may seek assistance from the Water Supplies Department
(Hotline no.2824 5000).
