Could bathroom mold be causing my kids' cough?« Back to Previous Page

Yes, the black mold you discovered beneath the silicone sealant is highly likely to be the cause of your children's persistent coughs and sore throats. The species you describe, often Stachybotrys chartarum (black mold) or Aspergillus niger, are known producers of mycotoxins and allergens. When disturbed, these molds release microscopic spores and volatile organic compounds (VOCs) into the air, which, when inhaled, are potent respiratory irritants. Children are particularly susceptible due to their developing immune systems and smaller lung capacity.

The conditions in your Discovery Gardens bathroom are a textbook case for rampant mold growth. The lack of a window and an underperforming extractor fan create a microenvironment of high humidity and stagnant air. Combined with Dubai's intense ambient humidity and the constant cycling of air conditioning (which can cause significant condensation), this provides the perfect breeding ground for mold. The sealant failure allowed moisture to penetrate and become trapped behind the waterproof barrier, facilitating hidden growth.

This situation requires immediate professional attention. DIY removal is strongly discouraged for several reasons: disturbing the mold without proper containment will aerosolize a massive amount of spores throughout your apartment, and simply reapplying sealant will trap the active colony inside, allowing it to continue growing and potentially compromising the wall structure.

As per UAE health and safety standards, a certified inspection and remediation protocol is essential. We at Saniservice recommend a professional inspection to identify the full extent of the contamination, including air quality testing to quantify spore levels. Our remediation process involves engineering controls (containment, negative air pressure), safe removal of contaminated materials, and application of EPA-approved antimicrobials. To properly address this health concern and prevent recurrence, please contact our specialists for a consultation. Call us at 800-MOLDS (800-66537) or email hello@saniservice.com.
