Black mold in bathroom causing kids' persistent cough?« Back to Previous Page

Yes, the black mold under your shower sealant is very likely contributing to your children's persistent cough and cold-like symptoms. Bathroom mold in Dubai's humid climate commonly releases spores and microbial volatile organic compounds (mVOCs) that irritate airways, particularly in children whose respiratory systems are more sensitive.

The constant humidity from showers in a windowless bathroom creates an ideal environment for mold growth behind surfaces where it's not visible. What you've found under the silicone is typically just the visible portion; the hidden growth within the wall is often more extensive.

For immediate action, improve ventilation by running the bathroom exhaust fan during and for at least 30 minutes after showers. Wipe down all wet surfaces thoroughly to reduce moisture. Do not attempt to bleach or scrub extensive growth yourself, as this can aerosolize spores and worsen the air quality.

The fastest and most effective solution is professional remediation. In serious cases like this with health symptoms, a certified inspector can assess the full extent of the problem, often using moisture meters and borescopes. Proper remediation involves removing the contaminated sealant and any affected building materials, followed by HEPA vacuuming and antimicrobial treatment to address the root cause.

For long-term prevention, consider installing a more powerful exhaust fan and using a dehumidifier if humidity remains high. Re-sealing should only be done after the area is completely dry and clean to prevent rapid recurrence.
