How to treat black mold on bedroom wall ourselves?« Back to Previous Page

The wall behind my wardrobe in our master bedroom has started showing these black spots, and the room has felt damp for the last couple of weeks since the weather changed. We live in a villa in Jumeirah and I'm worried it's spreading because my husband's started getting a stuffy nose in the mornings. What's the best way to treat this ourselves to stop it from getting worse before we call a professional?

Stop all DIY treatment immediately. What you're describing—black spots behind furniture, a damp feeling, and new respiratory symptoms—strongly indicates a moisture problem that needs professional diagnosis. In Dubai's climate, this is often condensation from AC units or a hidden leak.

Your priority is to contain the spread and protect your health. Move the wardrobe away from the wall to allow air circulation. Do not disturb the mold by wiping or spraying it, as this can aerosolize spores. Keep the bedroom door closed and the room's AC running to help reduce humidity.

For a temporary measure to help slow growth until a professional arrives, you can place a portable dehumidifier in the room. However, this only addresses the symptom, not the root cause.

The combination of symptoms and visible growth means this requires proper inspection. The treatment method depends entirely on identifying the moisture source—be it a leaking pipe, rising damp, or excessive condensation from your AC system. A professional will use moisture meters and thermal imaging to find the source. They can also take a sample for lab analysis to confirm the mold type, which dictates the correct remediation protocol. Attempting to clean it without fixing the underlying water issue will cause it to return quickly.
