cost to remove black mold and reseal shower in Dubai?« Back to Previous Page

The cost depends on whether the mold is only on the surface or has penetrated behind the tiles. For surface-level mold confined to the silicone sealant, a professional service typically includes removal, anti-fungal treatment, and re-sealing. For a standard bathroom, this is often a straightforward job.

If the mold has spread behind the tiles or into the grout, the scope and cost increase significantly, as tile removal and wall drying may be required. The only way to know the true extent is through a professional inspection, as hidden moisture is common in Dubai bathrooms due to high humidity and constant AC use creating condensation.

For a small, visible patch, you can attempt DIY with a hydrogen peroxide-based cleaner from ACE. The critical step is to completely remove the old silicone, let the area dry thoroughly for 24-48 hours, then apply a high-quality mold-resistant silicone sealant. However, DIY often fails because the root moisture issue isn't addressed, and improper application leads to quick recurrence.

Hiring a professional is necessary if the area is larger than a square foot, if the musty smell persists after cleaning, or for anyone with respiratory sensitivities. They should provide a moisture reading to check the walls and use lab-grade biocides to prevent regrowth. Always request a detailed assessment and quote before any work begins.
