Black mold in closet: professional cost or DIY fix?« Back to Previous Page

Black mold in a Marina apartment closet is a classic sign of condensation from the temperature differential between the AC-cooled room and the humid exterior wall. This is a very common issue in Dubai's coastal buildings. The recurring growth indicates a persistent moisture source you haven't addressed.

For a small, visible patch under 1 square meter, a thorough DIY cleaning with a vinegar or hydrogen peroxide solution can be effective. You must fix the moisture source first; ensure the AC is not set too cold, improve air circulation in the closet by leaving doors ajar or using a moisture absorber, and check for any leaks from the adjacent bathroom.

If the growth returns after addressing moisture and cleaning, or if you suspect it's inside the wall cavity (indicated by a musty smell or discoloration on the drywall), a professional inspection is necessary. They use thermal imaging to find hidden dampness and lab testing to confirm the mold type. The realistic cost for professional remediation of a single closet starts from AED 1,500, but varies significantly based on the extent of the infestation and required wall access. This cost is justified to ensure the root cause is solved and to prevent health impacts from prolonged spore exposure, especially with your allergies.
