How dangerous is black mold under my bathtub sealant?« Back to Previous Page

We've lived in our Discovery Gardens apartment for about a year, and for the past couple of months, I've been getting these weird allergy-like symptoms, especially after a shower. I just pulled back the silicone sealant around the bathtub and found a ton of black mold growing underneath it. I'm really worried this is what's causing my constant headaches and stuffy nose. How dangerous is this specific type of mold, and what's the most effective way to get my landlord to handle this properly?

The presence of black mold, often from the genus Stachybotrys chartarum, underneath bathtub sealant is a significant health and structural concern. In the high-humidity climate of Dubai, where year-round AC use can create condensation hotspots, this is a common but serious issue. The confined, damp, and dark space behind silicone is an ideal breeding ground.

The danger lies in the mycotoxins and microbial volatile organic compounds (MVOCs) released by the mold. For individuals with sensitivities, this can directly cause the symptoms you describe: persistent headaches, nasal congestion, sinusitis, and allergic reactions. Prolonged exposure can exacerbate asthma and lead to more severe respiratory conditions.

Regarding your landlord, your rights are protected under Dubai's rental laws (Law No. 26 of 2007). The landlord is legally obligated to maintain the property in a habitable condition, and a mold infestation of this nature, which is impacting your health, constitutes a breach of that obligation. You must formally notify them in writing (email is best for a paper trail), detailing the issue and its health impact, and request immediate, professional remediation. Do not attempt to remove it yourself, as improper handling can aerosolize the spores and worsen contamination.

This is not a simple cleaning job. It requires a professional inspection to determine the full extent of the growth, which often permeates deeper materials. A certified company like Saniservice will conduct air and surface sampling to identify the species and spore count, then execute a full remediation protocol including containment, HEPA filtration, antimicrobial treatment, and proper disposal. For immediate assistance, I recommend you call our experts at 800-MOLDS (800-66537) or email hello@saniservice.com to discuss an inspection and provide a report for your landlord.
