this wall is shared with neighbor at the back, some sorta clustered landed property.



Does anyone know what's the reason of it? usually early morning Cold air/water seep out of shared wall
also, know any contractor that capable to fix it, need they help to explain/prove also also when i file claim for defect from developer, under 3-y warranty.
Current developer-assigned sub-con+ architect said it observed as this wall is cool, but not an defect.
was told neighbor open air-cond too long, which i dun beliv, there's no way to fix it
now it's starting to grow mold

longkang, no water pipe/duct (according to architect), usually only rainning, water will flow thru it
it's open area, that put a big tangki at the center.

have to wait weekend, usually when dawn go out, sun falls only back.
may i know what's ur thought on this?

previously developer had assigned his kaki, to repaint the longkang with water-proof paint. no use
this longkang seldom expose, thus it's not clogged.
even sunny day, or rainy days all same

longkang, no water pipe/duct (according to architect), usually only rainning, water will flow thru it
it's open area, that put a big tangki at the center.

it's not from ceiling area, there's around 10cm from ceiling area, then only start seeping water/air.
just that i am not that tall enuf to take the full picture
