Why is mold growing despite cleaning?« Back to Previous Page

After the heavy rains we had last month, I noticed a moldy smell coming from my grandmother's room on the second floor. There are dark patches on her closet walls and it seems to be getting worse every day despite my efforts to clean. What can I do to prevent this issue from happening or recurring?

Mold growing despite cleaning can be quite frustrating. In Dubai and the UAE, humidity levels can reach uncomfortable highs during certain times of the year, especially after heavy rains like the ones we experienced last month. This makes the environment ripe for mold growth.

First off, it’s important to understand that mold spores are omnipresent in our environment. They float through the air and settle on surfaces, waiting for the right conditions—like high humidity or moisture—to flourish. In your case, the second-floor room is likely more prone to higher humidity due to its position in the building and the rain affecting the structure.

To address this situation effectively, start by performing a thorough inspection of the affected areas. Look beyond just visible mold; it’s possible that hidden moisture sources exist behind walls or in other hard-to-reach places. In Dubai, we are advised to follow local guidelines for indoor environmental quality, which include regular checks and maintenance to ensure buildings remain healthy.

Here are some practical steps you can take:

1. Professional Inspection: I would recommend scheduling a professional inspection by calling 800-MOLDS or emailing hello@saniservice.com. They have the equipment needed to detect moisture levels that aren't visible to the naked eye and can help pinpoint the exact source of the problem.

2. Address Moisture Source: Once you know where the moisture is coming from, tackle it head-on. This could be as simple as fixing a leaky pipe or more involved like ensuring proper drainage around your building. In Dubai, we have specific regulations regarding building and plumbing that need to be followed.

3. Enhance Ventilation: Boost air circulation in the room by opening windows when possible, using exhaust fans, or even installing dehumidifiers. The latter can significantly lower moisture levels and deter mold growth.

4. Dry Out Surfaces: If you find dampness on walls or other surfaces, ensure they are thoroughly dried out before attempting to clean them. Mold thrives in warm, wet environments so keeping things dry is key.

5. Use Anti-Microbial Cleaners: When cleaning the affected areas, use products that have anti-microbial properties to help prevent mold regrowth. Regular cleaning with a mixture of water and vinegar can also be effective.

6. Maintain Good Hygiene Practices: Encourage your grandmother to avoid bringing in wet or damp items from outside, as these could introduce new sources of moisture and spores into the room.

By taking these steps, you should see significant improvement in the mold situation. Remember, the key is addressing both visible and hidden sources of moisture to keep the environment healthy. If the problem persists, don’t hesitate to reach out for professional help.
