Is black mold causing my husband's cough and itchy eyes?« Back to Previous Page

We've lived here for 2 years and just noticed a patch of black mold in the corner of our master bedroom closet, which is on the outside wall of our villa in Jumeirah. My husband has had a persistent cough and itchy eyes for the last month, and I'm starting to worry it's connected. The closet doesn't smell too bad, but the wall feels a bit damp to the touch. Is it necessary to hire a professional mold inspector, or can we handle the cleanup ourselves with bleach?

Based on your description, it is highly probable that the mold growth is contributing to your husband's respiratory symptoms. The persistent cough and itchy eyes are classic indicators of exposure to mold spores and mycotoxins, which are irritants and allergens. The dampness you feel on the exterior wall is a critical clue, pointing to a potential condensation issue or a hidden moisture intrusion from the building envelope, both common in Dubai's climate due to high external humidity and constant air conditioning creating thermal bridges.

Attempting remediation with bleach is strongly discouraged. Bleach is ineffective on porous surfaces like drywall and wood, as it only removes the surface discoloration while leaving the root colony intact. More critically, it can aggravate the situation by releasing a high volume of spores and harmful chlorine fumes into the air during scrubbing, potentially worsening health symptoms. For a suspected case like this, a professional inspection is not just recommended; it is necessary.

A certified inspector will conduct a comprehensive assessment, including moisture mapping with thermal imaging and borescope inspections to identify the exact moisture source within the wall cavity. Air and surface sampling will be performed to identify the specific mold genus (e.g., Stachybotrys, Aspergillus) and spore concentration levels, which is vital for understanding the health risk and planning an effective remediation strategy. This scientific approach is essential to ensure the problem is solved at its source, preventing recurrence.

Given the symptoms and the location on an external villa wall, this requires professional diagnosis and remediation. I recommend you contact our specialists at Saniservice for a thorough inspection.
