How much does mold remediation cost for a bathroom?« Back to Previous Page

The black discoloration in your grout in Mirdif is a classic symptom of a persistent mold issue, exacerbated by Dubai's high humidity and the constant condensation cycle created by year-round AC use. Bleach is a surface-level biocide that does not address the root cause, which is moisture penetration into the porous grout and potentially the substrate behind the tiles.

For a standard bathroom (e.g., 10-15 sqm), professional mold remediation costs in the UAE typically range from AED 1,500 to AED 4,000. This variance depends on the severity and extent of the infestation. A localized surface treatment on grout lines would be at the lower end. However, if moisture has migrated behind the wall, the cost will increase to include demolition of affected tiles, treatment of the wall structure, and reinstatement.

Given that the problem recurs despite cleaning and is worsening with humidity, a professional inspection is absolutely necessary. Our certified inspectors use borescopes to non-invasively assess conditions behind walls and precise moisture meters to map the extent of the problem, which is critical for an accurate diagnosis and cost estimate. Attempting a DIY fix on a recurring issue risks the mold spreading into wall cavities, leading to more extensive structural damage and significantly higher remediation costs later.
