Black mold in bedroom: call management or cleaning company?« Back to Previous Page

Start by reporting it to building management immediately. In Dubai, landlords and property managers are typically responsible for addressing mold issues stemming from building-related problems like faulty AC systems or water leaks, as per common tenancy agreements.

Your situation points strongly to an AC-related cause. The location right above the vent and the recent humidity suggest the AC drain line might be blocked or the unit's insulation is failing, causing condensation to seep into the wall. Building maintenance should first inspect the AC system, clear any blockages, and repair the source of moisture. Merely cleaning the visible mold without fixing the root cause will lead to its rapid return.

Once the moisture source is repaired and the area is dry, a professional mold assessment is the next step for a case like this. The black spots spreading indicate an active colony. A specialist can take samples to identify the species and determine if the growth has penetrated behind the wall, which is common in these scenarios. Surface cleaning with bleach is ineffective and can aggravate the problem by releasing spores. Proper remediation involves containment, HEPA vacuuming, and antimicrobial treatment to prevent recurrence. For verifiable results, choose a provider that uses lab analysis and provides documented before-and-after data.
