How to permanently remove black mold on interior wall?« Back to Previous Page

Mold on an interior wall with constant AC use points to a hidden moisture source. The most common culprit in Dubai is condensation from an improperly insulated AC supply line running inside the wall cavity, creating a cold surface where humid air condenses. Alternatively, a hidden plumbing leak from an adjacent bathroom is possible.

For a spreading patch, DIY cleaning is a temporary fix. You must identify and stop the moisture source first. Wiping with diluted vinegar or a dedicated mold remover will clean the surface but it will return without solving the underlying problem.

In the UAE, tenancy law typically holds the landlord responsible for rectifying structural issues, including those causing dampness and mold. You should formally notify them immediately with clear photographs. They are obligated to investigate the cause, which likely requires a professional inspection to locate the moisture origin, perhaps with a thermal imaging camera.

Once the leak or condensation issue is fixed and the wall is fully dried, the affected area must be properly treated. Porous materials like drywall often need to be cut out and replaced if the mold growth is extensive. Simply repainting will trap spores and allow regrowth. A professional remediation service ensures safe containment during removal and uses antimicrobial treatments to prevent recurrence, which is crucial for a permanent solution in our humid climate.
