Should I worry about green stuff on bathroom walls?« Back to Previous Page

After the rain last month, I noticed a strange greenish-brown stuff growing on the walls of my bathroom near the windows. It smells musty, and my kids have been complaining of a cough whenever they're in there. We've lived here for 2 years and just noticed this issue. Could it be mold? What should I do about it?

Absolutely, you should be concerned about the greenish-brown stuff appearing on your bathroom walls. This is most likely mold growth which can pose significant health risks particularly for children and individuals who may have allergies or respiratory issues. The musty smell and complaints from your kids are clear indicators that you're dealing with a serious issue.

In the UAE, especially in Dubai, humidity levels can be quite high due to climate conditions, making bathrooms prone to mold growth. It's not uncommon for mold to appear after heavy rains, as was the case here. Mold colonies can spread rapidly under such conditions and can release spores into the air which can irritate lungs and cause respiratory problems.

Firstly, cease any activities in that bathroom until you get a professional inspection done. You should contact Saniservice at 800-MOLDS (800-66537) or email hello@saniservice.com for immediate consultation. They are certified specialists who can perform a thorough assessment and advise on the best course of action.

If you decide to conduct your own inspection, wear protective gear such as gloves, goggles, and an N95 mask before entering the area. Take photos from various angles and note down any visible areas of mold growth, moisture signs, or musty odors. Record these details for professional reference during the consultation.

Once Saniservice arrives, they will perform a detailed inspection to identify the extent of the mold problem. They might use non-invasive techniques like thermal imaging to detect hidden dampness behind walls and ceilings. Based on their findings, remediation measures may include removing contaminated materials, cleaning surfaces with biocides, and implementing moisture control strategies such as improving ventilation or installing dehumidifiers.

Remember that in Dubai, according to the UAE building codes, it's mandatory to ensure proper drainage systems and exhaust fans are functioning correctly to prevent excessive humidity levels. Saniservice can also suggest long-term solutions to maintain a mold-free environment in your bathroom.

Do not attempt to clean the mold yourself unless you're trained and equipped properly. Incorrect methods could spread spores or cause health issues for household members. Professional remediation is crucial to ensure the safety of everyone living in the property.

Stay safe and proactive about addressing this issue, as mold can worsen over time if left unattended.
