Black mold in shower: DIY fix or call maintenance?« Back to Previous Page

Black mold in bathroom silicone is common in Dubai's high humidity, especially when condensation forms between AC cycles. For a small area (under one square foot), you can attempt a DIY fix. First, completely remove the old silicone sealant and any visible mold. Use a mold-killing cleaner specifically designed for bathrooms; avoid bleach as it only surface-cleans and doesn't kill the roots. Let the area dry thoroughly for at least 24 hours with a fan or dehumidifier running. Then, apply a high-quality, mold-resistant silicone sealant to prevent regrowth.

However, if the mold has spread behind tiles or into the grout lines, or if there's a persistent musty smell even after cleaning, the issue is likely deeper. In apartments, this often indicates a leak from adjacent units or within the wall cavity itself. For cases beyond surface-level, contacting your building's maintenance is the correct step. They are responsible for investigating and repairing leaks in the building's structure. A professional inspection can determine if the moisture source is internal condensation or an external leak, which is critical for a permanent solution.
