Black wall mold causing coughs: clean myself or call pro?« Back to Previous Page

Black wall mold in a Dubai villa, especially after a period of high humidity, is a common but serious concern. Given that your children are coughing, this should be treated as a potential health issue and not just a cosmetic one.

For a small area (less than one square meter), you can attempt to clean it yourself with a detergent solution, but bleach is not recommended. It only removes the surface colour and does not address the root cause—the moisture. More importantly, scrubbing can release a large number of spores into the air, which can aggravate respiratory symptoms. The humidity and constant use of AC in our climate create perfect conditions for mold to return quickly if the underlying moisture problem isn't solved.

Because the mold is already affecting health and is on a porous surface like drywall, a professional inspection is strongly advised. They will identify the source of the moisture—which could be condensation from AC ducts, a small leak, or rising damp—and use containment procedures to safely remove the affected materials without contaminating your home's air. In Dubai, reputable remediation companies follow standards like the IICRC S520 for mold remediation. The key is to verify they will provide a post-remediation verification test from an independent lab to confirm the spore count in the air has returned to a normal level. This is the only way to be sure the environment is safe for your family.
