Am I responsible for fixing black mold in my rental?« Back to Previous Page

The black discoloration in your grout is almost certainly mold, a common issue in Dubai bathrooms due to the high humidity and condensation from showers and year-round AC use. Bleach cleaners only remove surface discoloration but do not address the root cause, which is moisture penetrating the porous grout.

Under standard Dubai rental contracts, the structural integrity of the apartment—including waterproofing, ventilation, and plumbing—is the landlord's responsibility. Since this is a recurring issue linked to persistent dampness, it likely falls under their purview for proper remediation. You are typically responsible for general cleaning and maintenance, but a recurring mold problem suggests an underlying issue like inadequate sealing or ventilation that they must address.

First, notify your landlord or property management company in writing, with photos showing the location and recurrence. Clearly state that superficial cleaning has been ineffective. They should arrange for a professional assessment to identify the moisture source, which is crucial for a permanent fix. In severe cases, this may involve regrouting, applying mold-resistant sealants, or improving bathroom ventilation.

For your immediate health, reduce humidity by running the bathroom exhaust fan for at least 30 minutes after showering and wiping down wet surfaces. Until it is professionally resolved, use a vinegar solution or a dedicated mold remover for grout, as these can be more effective than bleach at penetrating porous surfaces.
