Is black mold causing my husband's sinus symptoms?« Back to Previous Page

Based on your description, it is highly probable that the black mold in your closet is contributing to your husband's sinus symptoms. The persistent stuffy nose and sore throat that resolve when he leaves the home environment are classic indicators of a mold-related allergic reaction or irritation. The stored winter clothes act as a cellulose-based food source for the mold, while the recent high humidity in Dubai provides the perfect condition for proliferation, especially in a confined, poorly ventilated space like a closet.

In the UAE's climate, where high external humidity forces us to rely on year-round air conditioning, condensation and damp microclimates are common. Simply wiping the visible patch with bleach is insufficient, as it only removes surface discoloration and does not address the underlying moisture issue or the hyphae (root structures) penetrating the wall. This is why it often returns.

For a lasting solution, the affected materials (clothes, boxes) must be professionally cleaned or discarded. The wall itself requires specialized antimicrobial treatment to neutralize the colony. Crucially, the source of humidity must be identified; it could be from a condensate drain line from the AC unit servicing that room, a small leak, or simply inadequate airflow.

For a case like this, I strongly recommend a professional inspection. Our certified experts at Saniservice can conduct air and surface sampling to identify the mold species and spore concentration, which is vital for determining the correct remediation protocol and for your peace of mind.

DIY methods often exacerbate the problem by dispersing spores, so professional remediation is the safest and most effective course of action.
