Is greenish-black substance on closet wall mold?« Back to Previous Page

After the heavy rain we had last month, I noticed a strange greenish-black substance growing on the back wall of our bedroom closet. The smell is quite pungent and it seems to get worse during humid days. It’s concerning because my kids have been complaining of coughs and colds lately, which might be related. Has anyone else experienced mold issues like this in Dubai, and what can we do to prevent it from recurring?

Based on the description provided, it is highly probable that the greenish-black substance growing on your closet wall is indeed mold. Mold commonly appears as black, green, brown, or other colors and can produce a musty odor, especially during humid conditions, which fits your observations.

Mold growth in Dubai, particularly in areas like yours, could be due to several factors including high humidity, moisture from rain, inadequate ventilation, and poor air conditioning maintenance. In the UAE, there are no specific laws governing mold remediation, but it is crucial for maintaining indoor air quality and preventing health issues, especially among children.

The pungent smell and your kids' recent illnesses could be linked to the presence of mold. Mold can produce allergens that trigger respiratory problems such as coughs and colds, particularly in vulnerable populations like young children and individuals with asthma or allergies.

For accurate identification and proper remediation, it is highly recommended to seek a professional inspection by a certified environmental specialist. In Dubai, companies like Saniservice (contact 800-MOLDS or email hello@saniservice.com for assistance) offer comprehensive mold testing and remediation services that adhere to local standards.

In the meantime, take steps to prevent further growth:
1. Improve ventilation: Ensure proper airflow in your closet by opening windows occasionally if conditions permit.
2. Use a dehumidifier: Consider placing one near the closet to reduce moisture levels.
3. Clean regularly: Wipe down surfaces with a solution of water and vinegar or baking soda, which can inhibit mold growth.

Remember, addressing mold issues promptly is essential for maintaining a healthy indoor environment. If you suspect widespread contamination or if the situation worsens, do not hesitate to contact a professional for assistance.
