Should I worry about greenish growth on walls?« Back to Previous Page

After the heavy rains last month, I noticed a greenish-tinted growth starting to form on the bathroom walls near the shower curtain. It smells musty, even after turning on all the fans and opening windows. Can anyone give me advice on whether I should try tackling this myself or if I need to call in a professional?

Absolutely, the greenish growth you're noticing is indeed concerning and it's wise to take action. This growth sounds like mold, which can pose significant health risks especially for individuals with allergies, asthma, or respiratory issues. In the UAE, particularly Dubai, we've seen various cases where improper handling of moisture and humidity in bathrooms has led to extensive mold infestations.

Firstly, you should know that mold thrives in damp environments such as those found in bathrooms, which often have higher levels of humidity due to water use from showers or baths. The greenish tint is a common indicator of the presence of mold; this can vary depending on the type and maturity of the mold colony but is usually indicative of Pseudallescheria boydii or Cladosporium species.

Given your observations, it's crucial not to attempt any self-treatment without professional guidance. The UAE has specific regulations regarding environmental health and safety which mandate that any significant mold issue should be addressed by certified professionals. This ensures both the safety of occupants and compliance with local laws.

The first step is a thorough visual inspection to assess the extent of the mold growth. Check for signs like discoloration, fuzzy spots, or musty odors. Once confirmed, it's recommended that you call in experts such as Saniservice at 800-MOLDS (800-66537) or email them at hello@saniservice.com. They can conduct a detailed inspection to determine the type of mold and the best course of action.

Remember, certain types of molds are more dangerous than others. For example, Stachybotrys chartarum is known for its toxic nature. Professional remediation involves not only cleaning but also addressing the underlying moisture source to prevent future growth. This might involve fixing leaks, improving ventilation, or installing dehumidifiers.

In your case, since you've noticed this after heavy rains, it's possible that your bathroom has been compromised in terms of water management. Addressing this issue promptly can save significant costs and prevent health hazards.

In conclusion, while the situation may seem manageable at first glance, it’s best to err on the side of caution given the potential health implications. Professional intervention is recommended for a comprehensive solution that not only cleans up your current problem but also ensures long-term protection against mold growth in your bathroom.
