What's the cost to fix black mold in Dubai villa?« Back to Previous Page

The black discoloration in your Jumeirah villa's bathroom grout is a classic sign of a persistent mold infestation, likely exacerbated by Dubai's high humidity and constant air conditioning use, which creates ideal conditions for microbial growth. Scrubbing with bleach is a common but ineffective DIY approach; it often only bleaches the surface hyphae while the root mycelium remains deep within the porous grout and potentially the substrate behind the tiles, causing rapid regrowth.

For a 15 sqm bathroom, the cost of professional remediation is not a flat fee but is determined by the extent of the contamination. The critical factor is whether the mold has penetrated behind the tiles and into the wall structure, which requires invasive moisture mapping and inspection tools like borescopes to assess. Surface-level remediation, involving professional-grade biocides, abrasive cleaning, and sealing of grout lines, could range from AED 1,500 to AED 3,000. However, if the wall substrate is compromised, the scope becomes a demolition and rebuild project, including tile removal, wall drying, anti-microbial coating application, and re-tiling, which can escalate costs to AED 7,000+.

Permanent resolution requires addressing the source of moisture, typically poor ventilation or a hidden plumbing leak. We strongly recommend a professional inspection to determine the true scope.
