AC leak causing black mold: DIY or call landlord?« Back to Previous Page

That black mould behind your curtain is a classic sign of a chronic AC leak and Dubai's high humidity. You should contact your landlord immediately, as this is a maintenance issue they are typically responsible for under Dubai rental law (RERA's tenancy contract).

Do not attempt a significant DIY removal. Disturbing black mould without proper containment can aerosolize spores, spreading the problem. Your priority is stopping the source. Insist the landlord fixes the AC leak first—this is non-negotiable. For the mould itself, wiping the surface with a diluted white vinegar solution can temporarily reduce the visible growth, but it won't address spores within the wall.

Given the damp smell and hidden location, the mould has likely penetrated the gypsum board or insulation. This requires professional remediation: isolating the area, safely removing contaminated materials, and using HEPA filtration to clean the air. In JVC's high-humidity microclimate, a simple clean won't prevent rapid regrowth without fixing the moisture source and verifying the wall cavity is dry.

A professional inspection with moisture meters is wise to assess the extent of damage behind the wall. For health safety, especially with a persistent leak, a science-driven approach with post-remediation verification is the most reliable path.
