Could hidden mold cause the discoloration?« Back to Previous Page

After the heavy rain last month, I noticed a musty smell in the basement of my apartment, which we rarely use. When I checked closer, there seemed to be some discoloration on one of the walls near the corner by the laundry area. Could this just be old paint fading, or could it be hidden mold? Do you think I can handle cleaning it myself, or should I call a professional?

Hidden mold can indeed cause discoloration, especially under the right conditions. In the UAE, particularly during the wetter months such as September and October, humidity levels can rise significantly, leading to damp areas that may harbor mold growth. The musty smell you've noticed in your basement could be indicative of a mold issue, even if it's not visibly apparent.

The discoloration on the wall near your laundry area might indeed be due to hidden mold. Mold spores can produce pigments as they grow, which can lead to visible stains or discolorations. However, these are often hard to distinguish from paint fading or other non-mold related issues without professional assessment.

In Dubai and the UAE, it's crucial to adhere to local building codes and standards when dealing with mold remediation. According to the Building Code of Dubai (BCEP), buildings must be maintained in a condition that prevents the growth of biological contaminants like molds. If left unchecked, hidden mold can not only continue growing but also spread throughout your apartment or even into adjacent properties.

Handling such situations yourself might seem tempting due to cost considerations, but it's generally advisable to call in professionals for thorough inspection and remediation. Professional inspectors are trained to identify the presence of hidden mold using advanced equipment like thermal imaging cameras, moisture meters, and air quality samplers. They can also provide a comprehensive plan for removal and prevent future growth by addressing potential water sources or high humidity levels.

If you're concerned about the situation in your apartment, I recommend contacting Saniservice at 800-MOLDS (800-66537) or emailing hello@saniservice.com. They can provide a detailed inspection and offer solutions to ensure your living space is safe and healthy. Remember, addressing mold issues early can save you from more extensive damage and potential health risks.

In the meantime, avoid disturbing the area where you suspect hidden mold. Keep the affected area dry and clean if possible, but refrain from using any harsh chemicals or tools that could spread spores further into your apartment.
