Black spots on bedroom wall in JLT - mold from AC leak?« Back to Previous Page

Based on your description, that is very likely mold. The combination of visible black spots, high humidity, and an AC unit directly opposite the wall is a classic scenario in Dubai. The constant cooling creates condensation, and if there's a small leak in the AC drain line or a sealing issue within the unit itself, it can drip moisture directly into the wall, creating the perfect damp environment for mold to grow behind the wardrobe.

You should call a professional mold inspection company first, not a general cleaner or an AC technician. A proper inspection will identify the moisture source and the mold species. Many general cleaners will just wipe the visible spots without addressing the hidden moisture problem, guaranteeing it will return. An inspector will use moisture meters and thermal cameras to pinpoint the leak's origin. If it is indeed from the AC, they can then recommend a reputable, certified AC technician to fix the specific leak.

For a case like this in JLT, the process typically involves moving the wardrobe, conducting a detailed assessment to map the moisture, and taking air and surface samples for lab analysis to confirm the type and concentration of mold. Remediation then focuses on fixing the water source, properly removing the contaminated materials, and treating the area to prevent recurrence. Always ask for a company that provides documented before-and-after lab results, as this is your verification that the issue has been properly resolved.
