Is mold under stairs causing my kids' cough?« Back to Previous Page

Yes, the mold under your stairs is very likely causing your children's persistent coughs. The strong musty smell indicates active microbial growth, and inhaling the spores it releases is a common irritant, especially for young children. In Dubai's climate, enclosed spaces like under-stair cupboards are prime locations for mold due to high humidity and condensation, particularly when storing items like winter clothes that can trap moisture.

With a large, visible patch and a strong odor, this is a significant contamination. Do not attempt to clean it yourself with children present. Disturbing it will aerosolize a high concentration of spores, potentially worsening their symptoms. The safest first step is to isolate the area—keep the cupboard closed and the door to that room shut.

You need a professional inspection to identify the moisture source (likely a slow leak or condensation from a chilled water pipe) and assess the full extent, as mold often grows behind walls. Remediation for a case this severe requires containment, HEPA filtration to capture spores, and safe removal of contaminated materials. Any company you contact should be able to explain their containment procedures and provide a post-remediation verification report, ideally from an independent lab, to confirm the space is safe. This is a standard practice for reputable firms in the UAE.
