Is closet black mold causing our health symptoms?« Back to Previous Page

Our master bedroom closet on the outside wall has had a weird damp smell for a couple of months, but after the humidity last week, I actually saw black speckles growing on the leather shoes and bags I had stored in there. My wife and I have both been waking up with stuffy noses and scratchy throats, and it’s starting to worry us. Is this black mold, and could it really be causing these symptoms from just being in the closet?

Based on your description, it is highly probable that you are dealing with a mold infestation, and the black speckles on your leather goods are a significant visual indicator. The symptoms you and your wife are experiencing—stuffy noses and scratchy throats—are classic signs of exposure to mold spores, which are known allergens and respiratory irritants. These symptoms can absolutely be caused by a mold colony in a closet, as the HVAC system in your bedroom can circulate these spores throughout the air you breathe while sleeping.

The climate in Dubai is a primary catalyst for such issues. The extreme humidity, especially during summer months, combined with year-round air conditioning, creates perfect conditions for condensation, particularly on cooler external walls. This trapped moisture behind or within the wall provides the dampness mold needs to thrive. Your closet, being on an outside wall and containing organic materials like leather, is an ideal environment for proliferation.

Self-cleaning the visible mold is not recommended. Disturbing the colony without proper containment can aerosolize a massive amount of spores, significantly increasing your exposure and contaminating other areas of your home. Furthermore, visible growth is often just the tip of the iceberg; the main colony is frequently hidden within the wall cavity.

This situation requires a professional inspection. Our certified experts use tools like moisture meters, thermal imaging cameras, and air sampling to identify the full extent of the moisture source and contamination. Remediation must address the root cause (the moisture intrusion) and safely remove the mold according to strict protocols. For a proper assessment and a definitive solution, I strongly advise you to contact our team at Saniservice. Call us at 800-MOLDS (800-66537) or email hello@saniservice.com to schedule an inspection.
