Is shower grout mold my responsibility or landlord's??« Back to Previous Page

The grout between the tiles in my master bathroom shower has been turning black for a couple of months, and the damp smell is getting stronger. I'm in an older building in Deira, and I noticed it really started to spread after that period of heavy humidity we had. I wipe it down, but it just comes back. Am I responsible for cleaning this myself, or is this a maintenance issue I need to report to my landlord?

Black shower grout is almost always due to mold growth, which is common in Dubai's high humidity, especially after periods of heavy rain. The damp smell confirms an active issue. While wiping it is a temporary fix, it doesn't address the moisture source.

Your responsibility depends on the cause. As a tenant, you are typically responsible for routine cleaning and maintenance. However, if the mold is due to a structural issue like a hidden leak in the plumbing, poor ventilation, or faulty waterproofing/grout that has failed, it becomes the landlord's responsibility to fix the underlying problem.

For an older building in Deira, the root cause is often inadequate bathroom ventilation. If your extractor fan is weak or broken, report it to maintenance immediately. Landlords are generally obligated to provide and maintain functional ventilation systems under the Dubai Rental Law, as it's considered a key part of the property's habitability.

First, report the issue in writing to your landlord or building management. Clearly state the persistent black mold and strong damp smell, and note that it began after the humid period. Request they inspect for and repair any underlying leaks or ventilation faults. They may send a maintenance team to assess.

If the grout is simply old and porous, you may need to have it professionally cleaned and resealed to prevent moisture penetration, which could be your cost. For severe, recurring growth that causes a strong odor, a professional mold inspection can identify the species and source, which provides concrete evidence if you need to escalate the issue with your landlord.
