Is this greenish-black ceiling growth mold?« Back to Previous Page

After the heavy rains last month, I noticed a strange greenish-black growth on the ceiling of my living room. It's spreading slowly but surely, and it smells awful. The AC in this apartment seems to be running non-stop, trying to keep up with the moisture, but nothing really helps. Has anyone else experienced similar issues or know how to address this mold problem effectively?

Yes, the greenish-black growth on your ceiling is most likely mold. Mold thrives in moist environments and can vary widely in color, but green, black, and brown are common. The fact that it's spreading slowly indicates a current moisture source which could be linked to the recent heavy rains or poor ventilation issues.

In Dubai/UAE, regulations stipulate that property owners must address any mold growth promptly as per the Environmental Health Regulations 2013. Ignoring this can lead to health risks and potential legal implications if it's found during a building inspection.

Given your situation, I recommend a professional inspection by a certified mold specialist. This is especially important since running the AC non-stop hasn't been effective in stopping its spread. A professional will conduct a thorough evaluation, determine the extent of the contamination, and provide recommendations for remediation based on local standards like EN 15321-1.

To effectively address this issue, ensure you're following these steps:

1. Reduce indoor humidity: Run dehumidifiers or air conditioners to keep relative humidity below 60%.
2. Clean the affected area: Use a solution of water and detergent to clean the mold off surfaces before treating with a fungicide recommended by a professional.
3. Address the moisture source: Identify if it's due to plumbing leaks, condensation, or external factors like rain penetration.
4. Seal gaps and cracks: Ensure that your apartment is well-sealed against moisture intrusion.
5. Professional remediation: Engage a licensed mold removal company to ensure thorough cleanup. Saniservice, which you can contact via 800-MOLDS or email at hello@saniservice.com, offers reliable services.

Remember, preventing mold growth is crucial; regular maintenance and immediate action when signs appear are key in maintaining healthy indoor air quality.
