Is bathtub black mold making my kids sick?« Back to Previous Page

The black mold you found is very likely contributing to your children's persistent cough and allergy symptoms. Bathroom mold, particularly in a humid, poorly ventilated space like yours, releases spores and microbial volatile organic compounds (mVOCs) that are known respiratory irritants. This is a common issue in Dubai bathrooms without windows, where weak vent fans can't remove enough moisture from showers, leading to constant condensation and ideal mold growth conditions behind seals and tiles.

You should address this with urgency for your family's health, but there is no need for panic. For a remediation you discovered yourself, building management is typically responsible for fixing the underlying cause—in this case, the inadequate ventilation. Dubai's building codes and strata laws often mandate proper ventilation systems to prevent such issues. You should formally notify them to repair or upgrade the exhaust fan.

Do not attempt to remove extensive mold growth behind sealant yourself. Disturbing it will aerosolize a high concentration of spores throughout your home, potentially worsening the situation. For a proper fix, the old silicone must be completely removed, the area beneath treated by a professional remediator to kill the root structure, and then new sealant applied.

Before remediation, a professional inspection can confirm the mold type and full extent. After the fix, consistently run the bathroom fan during and for at least 30 minutes after showers. Wiping down wet surfaces and using a dehumidifier can help reduce moisture until the ventilation is resolved.
