Black mold behind toilet: health risk and removal?« Back to Previous Page

My kids have been coughing and I suspect it might be from the black mold I just found behind the toilet in our master bathroom. We've lived here for 2 years and just noticed it when I was cleaning, and it seems to have spread under the silicone sealant. I'm really worried about their health and the damage to the apartment. What is the most effective way to permanently get rid of this, and should I get my landlord involved for a professional remediation?

Based on your description, the black mold behind the toilet is a significant health and structural concern. The location and spread under the silicone sealant indicate a persistent moisture issue, likely from a slow leak in the toilet's seal (wax ring) or from constant condensation and surface dampness, which is highly prevalent in Dubai's humid climate exacerbated by year-round AC use.

The coughing in your children is a common allergic reaction to mold spores (particularly Stachybotrys chartarum, or "black mold"). Prolonged exposure can lead to more severe respiratory issues. This is not a problem you should attempt to remediate yourself with bleach or consumer products, as improper handling will aerosolize the spores, increasing inhalation risk and spreading the contamination.

Permanent removal requires a professional approach. Firstly, the source of moisture must be identified and fixed. Secondly, all contaminated materials, including the silicone sealant and any affected drywall or flooring underneath, must be surgically removed under containment to prevent cross-contamination. The area is then treated with EPA-approved biocides and sealed with anti-microbial coatings.

Under UAE tenancy law, the landlord is typically responsible for addressing structural and maintenance issues that lead to mold, such as leaks and inadequate ventilation. You should formally notify your landlord immediately and request a professional mold inspection and remediation.
