Could this green growth be mold?« Back to Previous Page

After the rain last month, I noticed a strange greenish growth on one of the walls in my son's bedroom. It started off as small spots but has grown to cover about half of the wall near his bookshelf. My daughter also mentioned she could feel a dampness when touching it. The AC in our apartment seems to be keeping everything cool, but I’m worried this might not be enough. Could this be mold, and is there anything we can do to fix it ourselves before it gets worse?

Yes, the greenish growth you're observing could indeed be mold. Mold is commonly found in damp and humid environments and can appear as green, black, white, brown, or yellow. It thrives on organic materials like wood, drywall, paper products, and fabric, making your son's bedroom bookshelf area a prime location.

In the UAE, particularly in Dubai, the climate can be favorable for mold growth due to high humidity levels during certain times of the year, especially after heavy rains or leaks. The dampness you noted when touching the wall could indicate active mold colonies. Mold spores are ubiquitous and will likely grow where there is moisture if conditions are right.

Mold not only affects the appearance but also poses health risks. It can trigger allergic reactions, respiratory issues, and exacerbate existing conditions like asthma. Given that your daughter mentioned feeling dampness, it's crucial to address this issue promptly.

Before attempting any DIY remediation, it’s highly recommended to get a professional inspection from a certified environmental service provider. In Dubai, you might want to consider companies such as Saniservice (contact 800-MOLDS or email hello@saniservice.com). They can provide a thorough assessment and determine the extent of mold contamination.

If a professional inspection confirms that DIY remediation is feasible, here are some steps you could follow:

1. Identify and eliminate moisture sources: Check for leaks in plumbing, windows, or roof, and ensure proper ventilation to reduce humidity levels.
2. Use appropriate personal protective equipment (PPE): Wear goggles, gloves, a respirator, and long sleeves when handling mold to prevent exposure.
3. Contain the area: Use plastic sheeting to cover unaffected areas of the room to prevent cross-contamination.
4. Clean affected surfaces: Use a solution of water and detergent or a commercial mold cleaner to scrub the walls gently. Rinse thoroughly with water and allow to dry completely.
5. Dry and disinfect: After cleaning, ensure the area is fully dried. Consider using dehumidifiers to maintain low humidity levels.

Regular maintenance can prevent future outbreaks by keeping your home’s environment dry and clean. Always aim for a relative humidity level of 40-60% in living spaces, which you can monitor with a hygrometer.

Remember, if the affected area is significant or if you experience any health issues related to mold exposure, don't hesitate to seek professional help immediately.
