Should we worry about musty smell in closet?« Back to Previous Page

After the heavy rain we experienced last month, I noticed a persistent musty smell coming from the closet in our living room. My roommate insists it’s not our fault because the AC is set to dehumidify, but I’m starting to wonder if we should be taking more action. Have you ever had similar issues in a rental property and what steps did you take to address them?

Absolutely, the musty smell in your closet could indicate an issue that warrants attention. In Dubai and the UAE more broadly, such smells are often associated with high humidity levels which can lead to mold growth. Dehumidification is indeed important but might not be sufficient given the climate and conditions you're experiencing.

In the aftermath of heavy rain, it’s crucial to ensure that your property is thoroughly drying out. The AC units in most properties here are equipped with dehumidifiers but they may not always provide adequate moisture control, especially if the load is too high or the system isn't properly maintained. I would recommend having a professional inspection by contacting Saniservice at 800-MOLDS (or email hello@saniservice.com) to assess your specific situation.

In general, indoor humidity levels in UAE should ideally be kept between 30-50% to prevent mold and mildew growth. Given the recent rain, it’s possible that your closet is retaining moisture which provides a perfect environment for mold spores to thrive. This could explain why you're smelling a musty odor.

To address this issue practically, consider these steps:
1. Ensure good ventilation in the affected areas by opening windows when possible or using exhaust fans.
2. Use additional dehumidifiers if your AC system isn’t sufficient. Look for units with high capacity and desiccant technology which can better handle wet conditions.
3. Clean any visible mold growth as soon as it's spotted, and treat the area with a fungicide approved for use in homes.
4. Inspect and clean out areas like air conditioning ducts and vents that might be contributing to moisture accumulation.

Remember, addressing such issues promptly is important not only for odor control but also to protect your health and the structure of your property from potential damage caused by mold growth.

Lastly, if you notice any structural damage or persistent high humidity despite your efforts, it would be wise to engage an experienced professional who can provide a comprehensive assessment and appropriate remediation.
