How to clean black mold and find AC leak in Dubai?« Back to Previous Page

The black patch indicates active growth, and its location near the AC suggests a condensation leak is likely. In Dubai's climate, AC units constantly pull humidity from the air, and a faulty drain line or insulation can cause water to drip inside walls.

For a patch smaller than one square meter, you can clean it yourself with a solution of diluted white vinegar or a specialist mold remover, wearing an N95 mask and gloves. However, this only addresses surface growth and will return if the moisture source isn't fixed.

Given it's behind boxes and the room feels damp, a professional inspection is strongly recommended to find the hidden leak and assess any spread inside the wall cavity. The inspection should include a thermal imaging scan to pinpoint the exact condensation point and a borescope inspection to see behind walls without unnecessary damage.

For reliable service, look for a provider with certified mold assessors who can deliver a detailed moisture map and lab analysis of the mold type. This evidence-based approach is critical; any reputable company should explain their diagnostic process clearly and provide a scope of work based on their findings, not guesses. The final step is remediation to remove the contaminated materials and repair the AC leak to prevent recurrence.
