Should I remove this mold myself or call a pro?« Back to Previous Page

Based on the description of spreading black and greenish spots, the onset after heavy rain, and the fact that you are experiencing physical symptoms like headaches, this is a situation that requires immediate professional attention. Do not attempt to handle this yourself with bleach.

The climate in Dubai, with its high humidity and reliance on year-round air conditioning, creates a perfect environment for mold growth, particularly after a rain event which can lead to hidden moisture intrusion. The location behind the wardrobe is a major red flag; it indicates a condensation issue or a potential leak in the building envelope that is creating a hidden, damp microenvironment. Bleach is ineffective on porous surfaces like drywall and plaster, as it only bleaches the surface mold while leaving the root system intact. It also fails to address the underlying moisture source, guaranteeing the mold will return, often more aggressively. Furthermore, bleaching can aggravate the situation by releasing a high volume of spores and harmful volatile organic compounds (VOCs) into your air, which is likely the cause of your headaches.

For a case like this, a professional inspection is non-negotiable. Certified experts, like our team at Saniservice, use thermal imaging and moisture meters to pinpoint the exact moisture source hidden within the wall cavity. We then conduct air and surface sampling to identify the specific mold species and concentration levels, which is critical for determining the correct remediation protocol as outlined by standards such as the IICRC S520. Remediation involves containment of the area with negative air pressure to prevent cross-contamination, safe removal of affected materials, and specialized antimicrobial treatment to ensure complete eradication.

Given your symptoms and the visible spread, I strongly advise against DIY methods. Please contact our specialists for a comprehensive assessment. Call us at 800-MOLDS (800-66537) or email hello@saniservice.com to schedule an inspection.
