Black mold in bedroom corner: who to call first?« Back to Previous Page

Contact building management first. In Dubai apartments, the building owner is typically responsible for structural repairs and external leaks, which are a common source of moisture in wall-ceiling corners. They should send their maintenance team to inspect for a potential leak from the roof, window frame seal failure, or a condensation issue from the AC unit.

Given your location in Marina and the recent humidity, this is likely a condensation problem exacerbated by the high ambient moisture. The wall above the window is a classic cold bridge spot where indoor humid air meets a cooler surface and condenses, creating the perfect environment for mold.

While building management handles the source, do not attempt to clean it yourself with bleach. This only removes surface discoloration and can push spores deeper. For confirmed growth, a professional assessment is needed to determine the extent within the wall. Remediation involves isolating the area, HEPA vacuuming, antimicrobial treatment, and addressing the moisture source to prevent recurrence. A company with its own microbiology lab can identify the species and provide a post-remediation verification test to ensure it's truly resolved.
