Black mold on wall: DIY clean or call professional?« Back to Previous Page

Based on your description of a recurring leak from the AC unit in JVC leading to black and green fuzzy growth on the skirting board, this is a situation that warrants significant caution. The humid climate in Dubai, especially during the summer and recent weeks, creates a perfect environment for rapid mold proliferation, particularly when combined with a constant moisture source like an AC condensate leak.

While small, superficial spots can sometimes be addressed with a diluted detergent solution, the presence of fuzzy growth indicates active colonization. Using bleach is not recommended; it is ineffective on porous materials like wood and drywall as it only bleaches the surface while leaving the root structure intact, and it can pose respiratory hazards in an enclosed space. Vinegar can be a mild fungicide but is often insufficient for an established colony.

Crucially, the visible mold on the skirting board is likely just the tip of the iceberg. The water from the leak will have wicked into the wall itself, and mold is almost certainly growing within the wall cavity, out of sight. This is a health risk and a building integrity issue.

For a case involving an ongoing leak, porous materials, and visible spreading, a professional inspection is strongly advised. Our certified inspectors use moisture meters and thermal imaging cameras to determine the full extent of the water damage and mold growth hidden behind walls. We operate in full compliance with Dubai Municipality's health and safety standards for environmental remediation.

The first step is to stop the source by having an HVAC technician repair the AC leak. Then, for proper remediation, I recommend you contact our team at Saniservice. We can provide a thorough assessment and a safe, effective remediation plan. Please call us at 800-MOLDS (800-66537) or email hello@saniservice.com for a consultation.
