Is bathroom mold under flooring urgent landlord responsibility?« Back to Previous Page

That is an urgent situation. Mold under flooring indicates a significant moisture issue, often from a leaking pipe, failed grout, or condensation buildup within the wall cavity. In Dubai's high humidity, this mold will continue to spread behind walls and under floors, degrading building materials and impacting indoor air quality.

Legally, your landlord is responsible for fixing the source of the moisture and the resulting damage, as this affects the property's structure and habitability. Your first step is to formally notify them in writing (email is best), include clear photos of the mold under the flooring, and request immediate repairs. They must address the leak and the resultant damage.

Do not attempt to remove it yourself. Disturbing it without proper containment will release a large number of spores throughout your apartment. A professional inspection is needed to identify the full extent of the moisture source and mold growth, which is often far more widespread than what is visible. They can provide the documentation your landlord may require. For a situation this advanced, remediation involves removing the affected flooring, drying the subfloor, and addressing the hidden moisture source.
