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

Yes, hidden mold behind bathroom sealant can absolutely be the cause of your children's persistent coughs and sore throats. The dark, damp space behind compromised silicone is a perfect breeding ground for mold, and the spores are likely being circulated every time the bathroom door opens or the AC runs.

In Dubai's high humidity, bathrooms are particularly vulnerable. Even with an exhaust fan, a closed window traps moisture, allowing condensation to build up in hidden cavities. The black mold you found is often Aspergillus or Cladosporium, species known to cause upper respiratory irritation, especially in children whose airways are more sensitive. The constant exposure from a hidden source like this explains why symptoms persist.

You need to address this immediately. Do not attempt to clean it yourself with bleach, as this can aerosolize a high concentration of spores and worsen the problem. The porous grout and wall behind the sealant are likely also contaminated.

For a case this severe with health symptoms, a professional inspection is strongly advised to assess the full extent. They will safely contain the area, remove the mold at its source, and treat the underlying moisture issue. The goal is to identify the species to understand the health risk and ensure the remediation is complete. Afterward, keep the bathroom well-ventilated by running the exhaust fan for at least 30 minutes after showers and occasionally opening the window to reduce humidity buildup.
