Can I fix basement mildew DIY?« Back to Previous Page

After the heavy rain last month, I noticed a musty smell starting to develop in the basement where we store our extra furniture. The walls seem damp, and there are some mildew patches growing on the corners near the floor. Is there anything I can do DIY-wise to address this issue before it gets worse?

Sure, I can guide you through the process of addressing mildew growth in your basement. However, it's important to understand that DIY solutions might be temporary and may not completely resolve the problem if the underlying moisture issues are severe or persistent.

Firstly, it is crucial to recognize that UAE regulations require professional inspection for mold problems, especially when they're extensive or difficult to manage. The Environmental Health Authority in Dubai mandates that any significant mold infestation should be evaluated by a certified specialist. However, for minor cases like yours, some DIY steps can help curb the issue temporarily.

To begin, you'll need to address the moisture problem which is likely the root cause of your mildew patches. Check the basement's drainage system and ensure it is functioning correctly. Any clogs or blockages should be cleared immediately. Additionally, inspect the building envelope for any leaks that could be allowing water intrusion. In Dubai, humidity can sometimes be a factor, so consider using dehumidifiers if necessary.

Next, clean up the visible mold. Use a mixture of 1 part bleach to 4 parts water or a specialized mold cleaner. Ensure you wear protective gear such as gloves and mask during cleaning. Scrub all surfaces thoroughly, including corners and edges where moisture tends to accumulate. Afterward, dry everything completely with fans if needed.

To prevent future growth, ensure proper ventilation in the basement by installing exhaust fans or opening windows (if weather permits). Also, consider implementing a vapor barrier on walls and floor to reduce dampness. Regular inspections are key; check for any signs of moisture accumulation monthly, especially after rain events.

Remember, while these steps can help manage mildew temporarily, they might not be sufficient if the environment remains excessively moist or if structural issues persist. It's advisable to consult with a professional mold remediation company like Saniservice (contact them at 800-MOLDS or email hello@saniservice.com) for an inspection and further guidance.

Mold can pose health risks, so take necessary precautions seriously. If you experience any symptoms such as allergies, respiratory issues, or skin irritation after handling mold, seek medical advice promptly.
