Could this black mold cause our coughing and headaches?« Back to Previous Page

Yes, the black mould behind your sofa is very likely the cause of the persistent coughing and headaches in your family. The continuous dampness from the AC condensate drip in your Deira apartment creates an ideal environment for mould to thrive, especially in our high humidity. The symptoms you describe—respiratory irritation and headaches—are a common reaction to inhaling mould spores and mycotoxins released into your indoor air.

This type of mould growth, particularly when hidden and long-term, poses a significant health risk, especially for children whose respiratory systems are still developing. The constant exposure can exacerbate allergies and asthma and lead to more severe sinus and respiratory issues over time.

Given the extent of the growth you've found, a professional inspection is strongly advised. DIY cleaning is not recommended for a patch this size, as improper handling can aerosolize a high concentration of spores, worsening the contamination throughout your apartment. A certified inspector can assess the full scope, identify the mould species (as some types are more problematic than others), and determine if it has spread into the wall cavity itself.

The remediation process should address the source first—fixing the AC condensate leak or improving drainage to prevent recurrence. The affected area will then need to be properly contained, removed, and the air professionally filtered. For verification, always request post-remediation testing from an independent lab to confirm spore counts have returned to safe, ambient levels before considering the job complete.
