Can I clean black mold myself or hire a professional?« Back to Previous Page

Based on your description, this is a situation that requires professional intervention, not a DIY cleaning attempt. The size of the infestation (a dinner plate), the persistent dampness in the wall, and, most critically, the health symptoms your children are experiencing all indicate a significant problem.

In Dubai's climate, the combination of high humidity and constant air conditioning creates ideal conditions for mold growth, particularly in poorly ventilated areas and on cold surfaces where condensation forms, like behind furniture on exterior walls. Using bleach or vinegar only addresses the surface discoloration you can see; it does not kill the hyphal roots penetrating the gypsum board nor address the underlying moisture source. This moisture is likely wicking through the wall from a potential leak or condensation issue, which must be professionally identified and remedied to prevent immediate regrowth.

Furthermore, disturbing the mold by cleaning can aerosolize a high concentration of spores and mycotoxins, potentially exacerbating your family's respiratory issues. The coughing your children are experiencing is a clear sign that the mold is already affecting air quality.

For a case like this, a professional inspection and remediation are essential. We follow strict protocols based on IICRC S520 standards, which involve containment, HEPA filtration to purify the air, safe removal of contaminated porous materials (like the affected drywall), and identifying/fixing the moisture source to guarantee the problem is solved permanently. For your family's health and a permanent solution, I strongly recommend you call our experts at 800-MOLDS (800-66537) or email hello@saniservice.com for a comprehensive assessment.
