Could hidden shower mold cause my kids' cough?« Back to Previous Page

Yes, hidden mold behind bathroom sealant can absolutely cause the respiratory symptoms you're describing. The black, fuzzy growth is likely releasing spores into the air, which are then circulated by your AC and inhaled, leading to persistent runny noses, coughing, and congestion, especially in children.

In a Deira apartment with high humidity and a weak bathroom fan, moisture gets trapped, creating a perfect environment for mold to thrive behind surfaces. The fastest way to deal with it starts with safety: avoid disturbing it further, as aggressive scrubbing can aerosolize a high concentration of spores. For a small patch, a thorough clean with a dedicated mold remover may suffice, but given its location under the sealant, the contaminated silicone must be completely removed and replaced to truly solve the problem.

However, because the issue is hidden and your children are symptomatic, a professional inspection is strongly advised. They can assess the extent of the growth you can't see behind walls and conduct air quality testing to identify the spore types and concentrations. This is crucial for determining the correct remediation protocol. In Dubai's climate, simply cleaning the visible mold without fixing the underlying moisture issue (like upgrading ventilation) means it will almost certainly return. A proper fix involves removing the source, treating the area, and ensuring the bathroom can dry effectively.
