How to safely remove mold from bedroom wall myself?« Back to Previous Page

My kids have been coughing more than usual, and I just found a patch of black and greenish mold behind their wardrobe in the master bedroom. It's on the wall facing the outside, and we've lived here in Jumeirah for two years without any issues until this last humid spell. What's the safest and most effective way to get rid of this myself without risking my family's health?

Based on the symptoms you've described and the location of the mold (on an exterior wall), this is a situation that requires immediate and careful attention. The persistent humidity in Dubai, especially during the recent spell, combined with year-round AC use, creates significant condensation issues within wall cavities, which is likely the source of your problem.

For a small patch (less than one square meter), you can attempt a careful DIY remediation. First, ensure your children and family members are not in the room during the process. Seal the area with plastic sheeting to prevent spore dispersion. Wear an N95 respirator, nitrile gloves, and safety goggles. Scrub the affected area with a solution of detergent and water. Avoid using bleach, as it does not kill the root structure and can release harmful fumes, especially in a confined space. After cleaning, the area must be thoroughly dried using dehumidifiers and fans; simple wiping is insufficient in our climate.

However, given that the mold is on an exterior wall and your children are exhibiting respiratory symptoms, I must strongly recommend a professional inspection. The visible patch is often just the tip of the iceberg. The mold growth within the wall cavity is likely far more extensive, and without addressing this hidden source and the underlying moisture issue (likely a thermal bridge or insulation problem), the mold will return rapidly.

For a definitive solution and to ensure your family's health, contact our certified team at Saniservice. We perform a comprehensive assessment, including moisture mapping and air quality testing, to identify the full extent of the contamination and the root cause. We then execute a controlled remediation following UAE health and safety protocols. Please call 800-MOLDS (800-66537) or email hello@saniservice.com for an immediate consultation. DIY methods on structural mold often worsen the spore spread, making professional intervention the safest choice.
