Mold behind wardrobe from AC: DIY or professional in Dubai??« Back to Previous Page

A wall patch behind a wardrobe from AC condensation is a common issue in Dubai due to the high humidity and constant AC cycling. For a small, surface-level patch (less than 1 square meter), a DIY approach can be attempted. However, simply spraying bleach is not a long-term solution; it may lighten the stain but won't kill the roots penetrating porous materials like drywall or plaster. A more effective DIY method is to scrub with a mixture of detergent and water, followed by a solution of white vinegar or a dedicated mould remover, then thoroughly drying the area with a fan. Crucially, you must identify and rectify the moisture source, which is likely inadequate insulation around the AC duct or a clogged condensate drain line.

Given the mould is spreading, it suggests a persistent moisture problem and potential penetration beyond the surface. In such cases, and especially with health concerns, a professional inspection is strongly recommended. They use moisture meters and thermal cameras to find the hidden extent of the damage and the exact condensation point. Professional remediation involves containing the area, removing affected porous materials safely, and applying antimicrobial treatments to prevent regrowth. The cost for a professional job is highly variable, depending on the area's size, the materials involved, and the extent of hidden damage. For a contained issue like this, it is often a targeted repair rather than a full-room remediation. You should request an on-site assessment from a certified provider to get an accurate scope and quote. Always ensure the company provides before-and-after lab testing documentation to verify the mould types and that the treatment was successful.
