Black mold in bathroom: clean ourselves or tell landlord?« Back to Previous Page

Based on your description, this is a classic case of bathroom mold growth, exacerbated by the high humidity and condensation prevalent in Dubai's climate. The persistent dampness and the emerging black spots, likely Stachybotrys chartarum (black mold) or Aspergillus, are significant concerns, especially given the onset of health symptoms like a stuffy nose and itchy eyes.

For immediate, limited surface mold on non-porous materials like tile, a thorough cleaning with a diluted bleach solution (1 part bleach to 10 parts water) or a dedicated EPA-approved fungicide can be attempted. You must wear an N95 mask, gloves, and eye protection. Scrub the grout lines meticulously. However, this is only a superficial fix. The underlying cause—excess moisture from inadequate ventilation—must be addressed. In the UAE, landlords are legally obligated under the rental law (Law No. 26 of 2007) to maintain the property in a habitable condition, which includes ensuring proper ventilation systems are functional. You should formally notify your landlord in writing about the defective ventilation and request a permanent repair.

Given the health symptoms, I strongly recommend against a DIY approach. Disturbing mold can aerosolize spores, worsening indoor air quality and health effects. A professional inspection is crucial to assess the extent of the growth, identify the moisture source, and conduct air quality testing. Our certified teams at Saniservice use thermal imaging and moisture meters to pinpoint hidden problems behind walls. We then perform safe, contained remediation and apply long-lasting antimicrobial solutions.
