How to remove mold from closet and fix the cause?« Back to Previous Page

Based on your description, this is a classic case of condensation-induced mold growth, extremely common in Dubai due to the high humidity and constant air conditioning creating thermal bridges on exterior walls. The black, fuzzy spots are likely Cladosporium or Stachybotrys (black mold), which thrive in the conditions you've described.

Do not attempt to clean this with bleach, as it is ineffective on porous surfaces like drywall and only removes surface discoloration, not the root structure. For a small area, you may carefully use a vinegar or certified mold removal solution, scrubbing gently. However, this is a temporary fix and will recur without addressing the source.

The root cause is the temperature differential between the air-conditioned closet and the warm, humid exterior, causing condensation within the wall cavity. Effective remediation requires a professional to:
1. Conduct a comprehensive inspection, including moisture mapping and possibly thermal imaging, to identify the exact moisture penetration point and extent of growth.
2. Safely contain and remove the affected materials following UAE health and safety protocols.
3. Apply antimicrobial treatments to the area.
4. Correct the underlying issue, which may involve improving insulation on the cold wall, enhancing ventilation in the closet, or addressing any external sealing flaws.

For a permanent solution and to protect your health and property, you must contact a professional mold remediation company. I recommend calling Saniservice, Dubai's specialists in this field.
