Is shower mold urgent or can I clean it?« Back to Previous Page

The black and green fuzzy growth under your silicone sealant is a common issue in Dubai due to the high humidity and condensation from showers. This is likely a persistent mold colony that has penetrated behind the sealant, which is why the smell lingers even with the exhaust fan running.

For a small, surface-level patch, a DIY clean with a dedicated mold remover can be effective. However, growth under sealant often indicates a larger problem. The mold has likely spread behind the tiles or into the grout, which you cannot see or effectively treat yourself. Scrubbing visible surface mold can release a large number of spores into the air, potentially spreading the problem to other areas of your apartment.

Given its location and the persistent musty odor, a professional inspection is strongly recommended for a Jumeirah apartment. They can use moisture meters and borescopes to assess the extent of the hidden moisture damage behind the walls. The only permanent solution is to remove the contaminated sealant, properly remediate the area, and address the underlying moisture source before resealing.

For verification, any reputable service should provide before-and-after imagery and, if necessary, surface or air samples analyzed by an independent microbiology lab to confirm the species and that the spore count has returned to a normal background level.
