Is black mold causing our persistent coughs and headaches?« Back to Previous Page

A hidden mold patch like that is very likely contributing to your family's symptoms. The persistent coughs and headaches are a common reaction to inhaling mold spores, which are now circulating every time the cupboard is opened. In Dubai's climate, a hidden leak combined with humidity creates an ideal environment for rapid mold growth, especially in enclosed, poorly ventilated spaces like under-stair cupboards.

For a patch of that size and given the health symptoms, professional remediation is strongly advised. Disturbing it yourself can aerosolize a massive number of spores throughout your home's air. The safest immediate step is to seal the area—tape plastic sheeting over the cupboard opening—and stop using it until it's addressed.

A proper inspection will identify the moisture source, which is critical to prevent recurrence. In villas, common causes are condensation from AC ducts running through the space or a leak from plumbing or ground moisture. Remediation involves containing the area, safely removing contaminated materials, and using HEPA filtration to clean the air. For health verification, post-remediation testing by an independent lab is the standard to confirm the spore count in the air has returned to normal levels.
