Landlord responsible for recurring bathroom mold and cracked grout?« Back to Previous Page

We've lived in our Discovery Gardens apartment for two years and just noticed a big patch of black mold growing in the corner behind the toilet where it's always a bit damp. I wipe it away but it comes right back within a week, and the grout seems to be cracking. Is this something I should fix myself with bleach, or is the landlord responsible for the repair since it might be a leak or bad ventilation?

Recurring mold behind the toilet, especially with cracked grout, is rarely just a surface issue and points to a deeper moisture problem. In Dubai's high humidity, this is common in bathrooms without adequate ventilation.

Your landlord is typically responsible for repairs related to the building's structure and systems. This includes fixing leaks from internal pipes, ensuring the ventilation system is functional, and remedying any waterproofing failures that cause persistent dampness. Cracked grout can be a sign of water damage to the substrate beneath the tiles, which is a structural repair. Document the issue with clear photos and a written notice to your landlord, referencing the recurring nature despite cleaning.

Using bleach only removes surface stain and does not address the moisture source; the mold will always return. For a persistent problem, a professional inspection can identify if the cause is a hidden leak, insufficient ventilation, or failed waterproofing. This diagnostic step is crucial before any repair, as simply re-grouting over a leak will lead to the problem returning quickly. In many cases, resolving the underlying issue is the only permanent solution.
