Black mold behind wardrobe on exterior wall: DIY or call maintenance?« Back to Previous Page

This is a classic Dubai mold scenario. The exterior wall facing the creek is likely cooler from AC, and the recent high humidity is causing condensation inside the wall cavity, creating the perfect environment for mold behind the wardrobe where air doesn't circulate.

You should move the wardrobe away from the wall immediately to assess the full extent and allow the area to dry. For a small patch (under one square meter), you can clean it yourself with a vinegar or diluted bleach solution, wearing an N95 mask and gloves. However, the fact it's on an exterior wall suggests the moisture source is likely internal condensation or a potential seepage issue from outside, which is a building envelope problem.

In the UAE, the responsibility for structural issues like external wall seepage typically falls on the building owner or maintenance company. You should report this to your building management. They are obligated to address the root cause to prevent recurrence. Simply cleaning the visible mold will not solve the problem if the hidden moisture remains.

Given its location and that it’s been developing potentially for some time, a professional inspection is wise to determine the full scope within the wall. The humidity here means mold can regrow quickly if the underlying dampness isn't resolved. A proper assessment will identify the exact moisture source and the type of mold present, which guides the correct remediation method.
