How to remove black mold myself or call a pro?« Back to Previous Page

We've lived here for 2 years and just noticed a patch of black mold in the corner of our master bedroom closet on the wall that faces the outside. It wasn't there during the last cleaning a few months ago, but with all the humidity lately, it's gotten worse. I'm really worried about it spreading and affecting our health. What's the most effective way to handle this myself, and at what point should I call a professional mold removal company here in Dubai?

Black mold in a closet on an exterior wall is a classic sign of condensation issues, very common in Dubai's climate. The temperature difference between the air-conditioned room and the hot, humid outside air causes moisture to form inside the wall, creating the perfect environment for mold.

For a small patch (under one square meter), you can handle it yourself. Wear an N95 mask, gloves, and safety glasses. Scrub the area with a mixture of detergent and water, or a solution of white vinegar. Do not use bleach, as it only removes the color and can push spores deeper into porous surfaces like drywall. After cleaning, ensure the area is completely dry. Address the moisture source—this is critical. Check that your AC is set to a consistent temperature to reduce humidity swings, and consider using a dehumidifier or moisture absorber in the closet.

If the mold returns quickly, covers a larger area, is in your HVAC system, or if anyone in the household experiences persistent respiratory issues like coughing or wheezing, stop and call a professional. Remediation companies with their own microbiology lab, like ours, can identify the species and its potential health risks through testing. They also have industrial-grade equipment to contain the spores during removal, preventing them from spreading to other parts of your home, which is the most significant risk of a DIY approach on larger infestations.
