How to permanently remove closet mold and check for leaks?« Back to Previous Page

That black mold on leather in a closet is a classic sign of a condensation issue, made worse by Dubai's high humidity. The wall is likely colder than the room's air, causing moisture to condense on its surface and inside the wall cavity—a perfect environment for mold. Your suspicion of a leak or insulation problem in an older Bur Dubai building is very valid.

First, address the items. For leather goods, wipe them down with a dilute white vinegar or rubbing alcohol solution. Do this outside to avoid spreading spores indoors. They must be completely dry before considering storage again.

However, cleaning alone is a temporary fix. The moisture source must be identified and resolved. This is a case where a professional inspection is strongly recommended. The mold on your belongings indicates a potential larger colony inside the wall, which you cannot assess yourself.

You need two types of professionals. First, a building surveyor or a reputable restoration company to conduct a moisture survey. They use tools like thermal imaging cameras and moisture meters to pinpoint exactly where the water is coming from—be it a leaking pipe, cracked external sealant, or inadequate insulation causing condensation. They can assess the wall cavity without unnecessary demolition.

Second, for confirmed mold growth inside the wall, a mold remediation specialist is required. They follow protocols to safely contain and remove the affected materials. In many cases, simply spraying a biocide on the surface is ineffective if the root cause inside the wall remains.

For a permanent solution, ask any inspector how they verify the moisture source and how they will check that the humidity level in the closet is brought down to a safe range (below 60% RH) after repairs. A trustworthy provider will explain this process and may recommend a dehumidifier for that room as a long-term preventative measure, given the local climate.
