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

The wall behind my wardrobe in the bedroom has these black and greenish splotches that I just noticed when I was rearranging. We've lived in this Jumeirah Park villa for two years and it's never been an issue, but the last few weeks have felt more humid than usual. What is the most effective way to treat this myself, or do I absolutely need to call a professional company?

That pattern of black and green splotches behind furniture is a classic sign of a condensation issue, very common in Dubai's climate. The wall is likely colder due to the constant AC, and with the recent higher humidity and the wardrobe trapping stagnant air, moisture condenses and mould grows unseen.

For a small, surface-level patch (under one square meter), you can treat it yourself. First, move the wardrobe away from the wall to allow complete air circulation. Wear an N95 mask, gloves, and safety glasses. Scrub the area with a microfiber cloth and a solution of white vinegar or a dedicated mould-cleaning detergent. Avoid bleach; it only lightens the colour but doesn't kill the root structure. Let the area dry completely.

However, the critical step is identifying and stopping the moisture source. In many villas, this is simply condensation from the temperature difference between the cool interior and humid air. Wiping down cold walls and improving airflow with a fan can help. If the dampness feels persistent or the plaster is soft, the issue could be more serious, like a hidden plumbing leak or insulation failure within the wall cavity.

If the mould returns quickly after cleaning, covers a large area, or you notice a musty smell in the room, a professional inspection is recommended. They use moisture meters and thermal cameras to find the exact source of water intrusion that you cannot see. For rental properties, Dubai Municipality regulations typically hold the landlord responsible for resolving structural leaks that cause persistent dampness and mould.
