How to safely clean black mold from storage cupboard?« Back to Previous Page

My kids have been coughing a lot for the past couple of weeks and I’m starting to panic. I pulled out their winter clothes from the storage cupboard under our stairs in Jumeirah, and the whole back wall is covered in this black, fuzzy patch that smells damp. We had that one really humid week last month and I think moisture got trapped in there. What’s the safest and fastest way to clean this to make sure my family isn’t breathing in toxic stuff?

As a certified mold remediation specialist in Dubai, your situation is unfortunately very common here due to our high humidity levels and condensation issues from year-round AC use. The black, fuzzy growth you describe is highly likely to be a significant mold colony, and disturbing it without proper containment and personal protective equipment (PPE) is extremely hazardous.

Do not attempt to clean this yourself. The act of cleaning will aerosolize the spores, putting your entire family at risk of inhalation, which is a probable cause of the persistent coughing. For a growth of this scale, professional remediation is mandatory. We adhere to strict UAE environmental and health & safety guidelines (as per Dubai Municipality and the UAE Ministry of Climate Change and Environment) which require containment, negative air pressure, and HEPA filtration to prevent cross-contamination.

The process involves sealing the area, using industrial-grade HEPA vacuums for spore capture, and applying specialized, UAE-approved antimicrobial agents to eliminate the root structure. The moisture source must also be identified and corrected; in your case, this likely involves improving ventilation and addressing condensation in that under-stair cupboard.

For the safety of your children, I strongly advise you to avoid the area and seek a professional inspection and remediation immediately. Our team at Saniservice is equipped to handle this safely and efficiently. Please call us at 800-MOLDS (800-66537) or email hello@saniservice.com for an urgent assessment. We can also conduct post-remediation air quality testing to confirm your home is safe.
