Black Mold in Closet: DIY or Professional Removal?« Back to Previous Page

Black mould hidden in a closet for months, especially with symptoms like a stuffy nose, warrants a cautious approach. The high humidity and constant AC use in Dubai create perfect conditions for mould to thrive in hidden, stagnant spaces like this.

For a patch smaller than one square meter, a careful DIY approach can be effective. Wear an N95 mask, gloves, and goggles. Scrub the area with a dedicated mould remover or a solution of white vinegar and water. Dry the area completely with a fan and fix the moisture source—this is critical. However, given its size, hidden nature, and the fact it’s caused symptoms, a professional assessment is strongly advised to rule out a larger infestation inside the wall.

Professional remediation is necessary if the mould returns after cleaning, the drywall or wood is soft (indicating rot), or the area is larger than one square meter. They use containment barriers and HEPA filtration to prevent spores from spreading to other parts of your home during removal. In Dubai, look for a company that provides a verifiable lab report identifying the mould species and confirming the post-remediation air quality is safe, which is a standard we uphold in our own work. This documented proof is essential for peace of mind, especially with health concerns.
