Can I treat closet mold myself or call a professional?« Back to Previous Page

Our master bedroom closet on the outside wall has developed some black spots in the corner after all the humidity this winter, and our clothes have a bit of a damp smell. We’ve lived in this Marina apartment for five years and this is the first time it's been this bad. Is this something I can tackle myself with a vinegar spray and better dehumidifiers, or do I need to call in a professional cleaning company to stop it from spreading?

Good question. This is a very common issue here in Dubai, especially in coastal areas like the Marina, where winter humidity can really get trapped in apartments. Based on your description, here's my professional assessment.

The black spots in the corner are likely surface mold growth, a direct result of the condensation that forms on that outside wall (which is likely a "cold bridge"). The damp smell on your clothes confirms elevated moisture levels. While a small, surface-level issue can sometimes be addressed by a homeowner, there are significant risks.

Using a vinegar solution is a temporary, superficial fix. It might wipe away the visible spores but won't address the root cause—the moisture trapped within the wall cavity or behind the baseboards. In our climate, this moisture will inevitably lead to regrowth, often worse than before. DIY methods can also accidentally agitate the spores, spreading the contamination to your clothing and the rest of the room.

For a case that's persisted for a season and is already causing odor, I strongly recommend a professional inspection. We need to determine the extent of the hidden growth and identify the exact moisture source. This isn't just about cleaning; it's about solving the humidity problem permanently with targeted drying and potential building envelope corrections.
