Could closed windows cause mold growth?« Back to Previous Page

After the heavy sandstorms we had last month, I noticed a persistent dry cough and itchy eyes whenever I spend time in my living room. The windows are always closed to keep out the sand, but there’s still this musty smell that lingers, even after cleaning. Could this be due to some kind of mold or allergens? What should I do to clean thoroughly and ensure it’s safe for everyone?

Closed windows can indeed lead to mold growth under certain conditions. In dubai and the uae, we often face varying climates that include high humidity during summer months and sandstorms which bring dust and sand into homes. When these elements mix inside without proper ventilation, it creates an environment where moisture can accumulate - a perfect breeding ground for molds.

In your case, the persistent dry cough and itchy eyes might be linked to mold spores or other allergens present in the air. Mold thrives in damp environments and can produce allergens that irritate respiratory systems. Even with windows closed, indoor humidity levels can rise due to activities like cooking, showering, or using humidifiers, which can create moisture-laden conditions ideal for mold growth.

To ensure a thorough clean and maintain a safe environment:

1. Assess Humidity Levels: Use a hygrometer to monitor the relative humidity in your living room. Aim for levels below 60% to minimize mold growth potential.

2. Dry Out Moist Areas: Use dehumidifiers or air conditioners to reduce moisture content in the air. Ensure that they are regularly cleaned and maintained according to manufacturer guidelines, especially as we move into cooler months where condensation might be more prevalent.

3. Inspect for Mold: Look for visible signs of mold growth, which can often appear as green, black, brown, or white patches. Pay attention to areas like corners behind furniture, under carpet edges, and around windowsills.

4. Clean Properly: Use a mixture of water and vinegar or baking soda to clean affected surfaces. For stubborn stains, consider using commercial mold removers that are approved for use in residential settings. Always wear gloves and ensure good ventilation during cleaning activities.

5. Professional Inspection: If you find any signs of significant mold growth or if symptoms persist despite your efforts, it's advisable to call a professional environmental inspection service like Saniservice at 800-MOLDS (800-66537) for an expert assessment and remediation plan.

Remember, maintaining good indoor air quality is crucial, especially in the uae where we experience unique weather patterns. By addressing moisture issues promptly and ensuring proper ventilation, you can significantly reduce the risk of mold growth and improve your living environment's overall health.
