How to stop moisture and mold in Dubai apartment wall?« Back to Previous Page

The dampness behind your wardrobe is likely condensation from the temperature differential between your air-conditioned room and the humid corridor wall, a very common issue here. Simply cleaning the visible mold won't stop it from returning; you must address the moisture source.

First, move the furniture away from the wall permanently to allow air circulation. Wipe the mold off the wall using a microfiber cloth with a diluted detergent solution; avoid bleaching as it only removes the colour, not the organism. For the underlying moisture, your best solution is to improve insulation. An insulation board or a thermal barrier paint applied to that interior wall can significantly reduce the condensation by balancing the surface temperature with the room's air.

Since the wall is damp, there may be a more serious issue behind it, like a small leak from the corridor's AC condensate drain or pipework. For a persistent problem on a shared building wall, you should also inform your building management. Dubai Municipality's Public Health & Safety Department requires building owners to maintain premises free of dampness and mold, so they are obligated to investigate potential leaks from common areas.

Given the symptoms you've described, a professional inspection is wise to identify the exact mold species and the full extent of the moisture. Remediation often requires specialized drying equipment and antimicrobial treatments for the wall cavity to ensure it's truly resolved. A company with a microbiology lab can provide a culture to identify the type of mold, which is crucial information for understanding any potential health impacts and for properly addressing the building management.
