Is musty smell and black spots mold related?« Back to Previous Page

After the heavy rains last month, I noticed a musty smell and some strange black spots on the ceiling of my child’s bedroom. It’s worrying because they’ve been coughing more lately. Could these be signs of mold growth? What should I do to address this issue safely at home?

Yes, the musty smell and black spots could indeed be related to mold growth. Mold is a common problem that can develop in damp environments, especially after heavy rains like those experienced recently. In Dubai/UAE, such conditions can foster an ideal environment for mold proliferation.

Mold thrives in warm temperatures (between 20-37°C) and humidity levels above 60%. The ceiling of your child's bedroom seems a likely spot given the potential for water intrusion from the rain. Mold colonies often appear as black or greenish spots, which could explain what you've observed.

Given the health concerns—your child's increased coughing—it is prudent to address this issue promptly. In the UAE, it’s advisable to call professionals at 800-MOLDS (800-66537) or email hello@saniservice.com for a comprehensive inspection and remediation.

If you decide to undertake some preliminary steps before professional help arrives:

1. Ventilation: Increase air circulation by opening windows if weather permits.
2. Dryness: Use dehumidifiers and fans to reduce moisture levels, especially in affected areas.
3. Cleaning: If the mold is minor (less than 0.5 square meters), you can attempt a clean-up using gloves, goggles, and a respirator mask. Use a solution of water and detergent or a commercial mold cleaner.

Remember, attempting DIY remediation might pose health risks if not done correctly, especially for large areas or when the spores are airborne. The UAE has specific guidelines around mold remediation that ensure safety and effectiveness. For instance, certain materials like porous surfaces may need to be replaced depending on the extent of contamination.

Professional services can identify the type of mold, assess the risk level, and provide a safe removal plan. They will also ensure that all areas are properly treated and cleaned to prevent re-infestation.
