Hire professional for black bathroom mold in Dubai? Cost?« Back to Previous Page

The grout between the tiles in my master bathroom in our Jumeirah Village Circle apartment has been turning black for a few months now. I’ve tried spraying bleach cleaner, but the smell and the spots keep coming back, especially behind the toilet where it’s hard to reach. I’m worried it’s getting worse with the humidity and might be affecting the walls. For a problem like this in Dubai, is it better to just hire a professional mold removal company, and what’s a realistic cost I should expect for a single bathroom?

Based on your description, this is a classic case of persistent mold growth, a common issue in Dubai bathrooms due to the high ambient humidity, condensation from year-round AC use, and inadequate ventilation. The black discoloration in the grout is likely Aspergillus niger or similar species, which thrives in damp, poorly lit areas like behind toilets.

Spraying bleach is a common but ineffective DIY approach. Bleach is mostly water, which the mold can feed on, and it only superficially bleaches the surface hy
