Is black mold under bathtub causing my kids' cough?« Back to Previous Page

Black mold under bathtub sealant is a very likely cause of persistent coughing, especially in children. The damp, dark, and warm environment is ideal for mold growth, and the spores become airborne as you disturb the area. This directly irritates the respiratory tract, leading to coughing, congestion, and worsened allergy symptoms.

In Dubai's climate, with high humidity and year-round AC use, bathrooms are particularly vulnerable. AC systems can circulate these spores throughout your apartment, not just contain them to the bathroom. The first step is to stop the moisture source. This often means re-grouting and replacing the silicone sealant with a high-quality, mold-resistant product after the area is completely dry.

For a discovery of this scale, especially with health symptoms present, professional remediation is strongly advised. DIY cleaning with bleach often fails to address the root moisture problem and can aerosolize more spores. A proper remediation involves isolating the area, removing the contaminated materials, and using HEPA filtration to clean the air. The goal is to remove the mold, not just kill it, as dead spores can still cause allergic reactions.

You can request a post-remediation verification test from an independent indoor health company to confirm the spore count in your air has returned to normal levels. This provides peace of mind that the environment is safe for your children. Given the connection to their health, addressing this properly is a priority.
