Black mold in closet: urgent professional needed?« Back to Previous Page

Black mold in a closet is a health concern and should be addressed promptly, especially with the strong musty smell you describe. The smell indicates active microbial growth, which often means the visible spots are just a small part of the problem. In Dubai’s high humidity, mold can spread quickly behind walls and into stored items.

For a small, visible patch, you can clean it with a vinegar solution (not bleach, as it doesn't kill the roots and can worsen indoor air quality for a time). However, given the odor and its location on an interior wall, the moisture source is likely hidden, such as condensation from an AC pipe in the wall, a small leak from an adjacent bathroom, or simply trapped humid air. DIY cleaning will remove the surface stain but not fix the root cause, so it will almost certainly return.

You need a professional inspection. They will use moisture meters and borescopes to find the source of the dampness behind the wall. Remediation is not just cleaning; it’s about solving the humidity issue first. For porous materials like drywall, removal and replacement is often the only permanent solution.

In the UAE, reputable companies should follow international guidelines like the IICRC S520 for mold remediation. The process should include containment to prevent spores from spreading to other parts of the home during removal. Given your description, this is not a low-risk situation, and professional assessment is strongly recommended to protect your family's health and your property.
