Mold removal cost in Dubai bathroom: DIY or professional?« Back to Previous Page

The grout between the tiles in our master bathroom shower has been turning black for a while, and I just found patches of fuzzy mold behind the toilet where it’s always damp. We’re in an older building in Bur Dubai and I’m worried it’s spreading. What’s the realistic cost range for a professional mold removal service for a standard-sized bathroom here, and is it something I can realistically tackle myself with cleaners from Ace Hardware?

Black mould in bathroom grout and behind toilets is extremely common in Dubai due to the constant high humidity and condensation. The realistic approach depends entirely on the extent.

For a small, surface-level patch (under one square foot), a thorough DIY approach can be effective. Use a hydrogen peroxide-based cleaner or a diluted bleach solution, scrubbing the grout and all surfaces behind the toilet. The critical step is to fix the moisture source—improve ventilation by running the exhaust fan longer and wiping down wet surfaces after showers.

If the mould is widespread, has a strong musty odour, has penetrated behind tiles, or keeps returning after cleaning, a professional assessment is strongly recommended. In older Bur Dubai buildings, moisture can seep into underlying walls. Pros use moisture meters and borescopes to assess hidden damage you can't see. Remediation cost is driven by the square footage affected and the labour needed to address the root cause, such as resealing or repairing hidden leaks. Reputable companies provide a detailed assessment and quote upfront, often including post-remediation verification to confirm the mould and moisture issue is resolved.
