Mold on wall from AC leak: need professional in Dubai?« Back to Previous Page

Yes, you need a professional remediation company. The combination of a persistent leak and a recurring black mould colony indicates a serious moisture issue that DIY methods cannot address. Vinegar only removes surface discolouration; it cannot reach the mould growing deep within your wall's drywall and insulation.

In Dubai's climate, this is a critical issue. The high humidity provides a constant source of moisture that allows mould to thrive, especially when coupled with condensation from an AC leak. The wall cavity acts like an incubator. A professional team will first stop the leak at its source—your AC unit—then contain the affected area to prevent spores from spreading during remediation. They will remove and dispose of the contaminated porous materials (drywall, insulation), treat the underlying structure, and verify the area is dry and clean through post-remediation testing.

For a single wall, the cost is not typically a flat fee but depends on the extent of the damage discovered. The final price is driven by the area of contamination, the depth of moisture penetration, and the required containment procedures. You should request a detailed, on-site assessment from a certified provider. Any reputable company will provide a scope of work and a firm quotation after this inspection, which is often conducted at no cost. Look for companies that follow IICRC standards and can provide verifiable before-and-after data from their own or a third-party lab.
