How to treat and prevent damp black mold behind wardrobe?« Back to Previous Page

My kids have been coughing and I suspect it's from the black spots I just found behind the wardrobe in our master bedroom. We've lived in this Mirdif villa for 2 years and just noticed it, probably because we moved the furniture for cleaning. The wall feels slightly damp to the touch. What's the best way to treat this myself to stop it from spreading and make sure it doesn't come back?

The damp black spots behind your wardrobe are likely mold, a common issue in Dubai villas due to high humidity and year-round AC use causing condensation on cooler walls.

First, address the moisture source. In Mirdif, this is often condensation from the temperature difference between the AC-cooled room and the warmer wall. Moving the wardrobe slightly away from the wall can improve air circulation. Check for any hidden plumbing leaks, which are another frequent culprit.

For treatment, wear an N95 mask and gloves. Mix a solution of one part white vinegar with four parts water. Lightly spray the area and scrub with a stiff brush. Avoid bleach, as it only removes the color and doesn't kill the root structure. After scrubbing, wipe the area dry and use a fan to ensure it is completely moisture-free before repositioning the furniture.

To prevent recurrence, a dehumidifier in the room can help, especially during the more humid months. Consider applying an anti-condensation paint to the wall after the mold is removed. If the wall still feels damp after your initial clean, the issue may be more significant, such as a breach in the building's vapor barrier or a more serious leak. In such cases, a professional inspection with moisture mapping can identify the exact source, which is critical for a permanent solution, especially with children experiencing respiratory symptoms.
