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 |

QUOTE(mini orchard @ Mar 17 2022, 10:03 PM) Is it possible to access the tangi area to take some photos? 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 |

QUOTE(mini orchard @ Mar 17 2022, 10:31 PM) If the leak starts from the ceiling area, then is unlikely the AC. The installation of the AC wont be so high. it's not from ceiling area, there's around 10cm from ceiling area, then only start seeping water/air. Since your photo is 'incomplete' is difficult to see the overall leaking. just that i am not that tall enuf to take the full picture This post has been edited by garygan: Mar 17 2022, 10:36 PM |

QUOTE(nihility @ Mar 17 2022, 10:43 PM) If it only have water in the early morning, then yes, it was due to the air conditioning. The cold surface of the wall + low dew point temperature in the morning causes the water to condensate. my question is: The similar occurrence can be observed at your car windscreen. Early morning you will see the water droplets form on the windscreen. Condensation happens only when these 2 conditions are present ( must be together, any one of the condition absent, it will not happen). 1) Cold surface below dew point temperature. 2) Present of external air / fresh air with high humidity (our country easily 75-90% during morning) i lived at condo for quite long, even my home-town, is landed, linked house. why it never happen before? does it mean: 1) my neighbor open it with ultra-long, ultra-low temperature that caused it？ 2）could it be the pipe they sealed (if they did) has leakage? QUOTE(nihility @ Mar 17 2022, 10:43 PM) a) Install AC outdoor near to this wall, let the heat rejection of the AC outdoor increases the wall temperature surface when it is running. You must run this AC frequently. this (a) the developer did suggest.b) Apply a layer of insulation to the wall. The insulation will prevent the wall become to cold thus eliminating the condition 1).
