Can high humidity cause mold growth?« Back to Previous Page

After the rain last month, I noticed a persistent musty smell in my bedroom closet. The humidity has always been an issue in this old building, but it seems worse lately with the AC struggling to keep up. My kids have been complaining of coughing and sneezing every time they go into that room. What can I do to prevent this from happening or recurring?

High humidity sure can lead to mold growth and it's an issue many folks in the UAE, especially those living in older buildings like yours, face. In Dubai, we often experience high humidity levels due to our climate, which makes indoor air quality a critical concern. The musty smell you're noticing could be from mold spores multiplying in damp areas of your closet.

In old structures, ventilation systems might not always be up to modern standards, and this can lead to moisture buildup, especially if the AC is struggling to manage humidity levels effectively as it seems to do in your case. Mold thrives in environments with high relative humidity – typically over 60% – so if you're experiencing persistent mustiness or seeing signs of mold growth, it's important to address it promptly.

Firstly, I'd recommend increasing the airflow and ventilation within the closet by using dehumidifiers or ensuring that there are proper exhaust systems in place. For instance, a portable dehumidifier can be very effective at reducing humidity levels, but make sure you clean and maintain it regularly as per manufacturer's instructions to avoid any overflow issues.

Secondly, inspecting for leaks is crucial. Check your roof, walls, and even the foundation of your building for signs of water intrusion that might be causing localized high moisture conditions. This can sometimes be overlooked in older buildings where structural integrity may not be as robust as it should be.

Moreover, keeping an eye on the condition of your AC unit isn't just about cooling; ensuring it’s functioning properly is also key to maintaining a healthy indoor environment. If you’re experiencing persistent issues with humidity despite having a functional AC system, it might be worth considering professional consultation or even replacing the system if necessary.

If these steps don’t seem to help, or if you notice visible signs of mold growth such as discoloration on walls or ceilings, it’s highly advisable to call in professionals for an inspection. In Dubai, companies like Saniservice offer reliable and experienced services that can assess your situation and provide the best solutions tailored to your needs.

Remember, keeping a close watch on humidity levels and addressing issues promptly can prevent mold growth and keep you and your family healthy. Don't hesitate to reach out if you need further assistance or want more specific advice based on your building's unique characteristics.
