How to dehumidify a moldy closet on an interior wall?« Back to Previous Page

Based on your description of a damp interior closet in a Marina apartment with recurring mold, you are experiencing a classic issue in Dubai's climate. The primary culprit is likely a combination of high ambient humidity and a lack of adequate air circulation within the enclosed space, despite running your AC. The cold air from your room is not effectively penetrating the closet, causing a microclimate where warm, humid air from the bathroom or kitchen infiltrates and condenses on cooler surfaces and contents, like your jackets.

The most effective technical solution is to mechanically introduce dry, conditioned air into the closet. Simply using a desiccant bag is insufficient for the UAE's humidity levels. You need to install a passive ventilation system. This involves cutting a vent grille into the closet door (preferably at both top and bottom) to allow your room's conditioned air to convect through the space. For a more active solution, a small, ultra-quiet duct fan can be installed in the ceiling or wall to actively exhaust stagnant air from the closet into the return air plenum of your AC system, creating negative pressure that draws dry air in.

Crucially, this is not just a moisture issue but a mold issue. The dark spots on your jackets indicate an active colony. The mold must be professionally remediated first. DIY cleaning with surface sprays often misses hidden hyphae deep within materials and the structure, guaranteeing regrowth. We must identify and eliminate the moisture source, which may require thermal imaging to find hidden condensation points.

Given the recurring nature over two years, a professional inspection is strongly recommended to assess the extent of the growth and develop a permanent solution. Our certified experts at Saniservice use industry-standard protocols compliant with Dubai Municipality guidelines to safely remediate the mold and advise on corrective ventilation measures.
