Your first step should absolutely be to contact your building management or landlord immediately. Under Dubai regulations, the structural integrity of the building, including the waterproofing of external walls, is the responsibility of the property owner. The mold is likely a symptom of a larger issue, such as a hidden water leak from an air conditioning condensation line or a breach in the building’s external waterproofing envelope. Document the issue with clear photographs and formally notify them in writing.

For your safety, do not attempt a significant DIY removal. Disturbing the mold by wiping or scrubbing will aerosolize the spores, potentially causing respiratory issues and spreading the contamination throughout your apartment. The presence of black mold, which could be Stachybotrys, requires professional assessment and remediation.

A certified inspector will use moisture meters and thermal imaging to identify the exact moisture source hidden within the wall. Remediation involves isolating the area with containment barriers, using HEPA filtration to clean the air, and safely removing the contaminated materials. Simply cleaning the surface is insufficient if the moisture problem inside the wall is not resolved.

For a professional inspection and a certified remediation plan, I strongly recommend contacting our specialists at Saniservice. Call 800-MOLDS (800-66537) or email hello@saniservice.com. We can provide a detailed report for your landlord and ensure the problem is solved safely and permanently.
