Should I handle this mold myself or call a pro?« Back to Previous Page

After the heavy rains last month, I noticed a suspicious greenish-brown patch growing on the wall behind the shower in my bedroom. It smells musty even after airing out the room. Can someone with basic knowledge handle this mold chiller myself, or should I call in a professional?

Handling mold growth yourself can be challenging and potentially risky. Given the specifics of your situation—particularly the greenish-brown patch behind your shower wall—it's important to approach this with caution.

Firstly, it’s crucial to identify the type of mold you're dealing with. In the UAE, especially after heavy rains like those experienced last month, a common mold that can appear is Cladosporium or Stachybotrys. Both require different treatment methods due to their varying levels of toxicity and growth patterns.

To properly address this issue, start by ensuring adequate ventilation in your bathroom to reduce moisture accumulation. Open windows if possible, or use exhaust fans to minimize humidity levels. This step alone can sometimes help prevent further mold growth.

Next, you should clean the affected area using a solution of 1 cup of bleach per gallon of water (or an EPA-registered fungicide). Scrub the surface thoroughly and allow it to air dry completely before reassembling any walls or fixtures. For mild cases, this might be sufficient. However, if the mold persists or spreads, professional intervention is highly recommended.

In Dubai/UAE, you are required to comply with local building codes that may affect how you handle mold issues, especially in residential properties. The UAE Environmental Protection Authority (EPA) and the Ministry of Municipality and Rural Affairs have guidelines for mold remediation which should be adhered to. For a serious case such as yours, it would be wise to call a professional service.

Professional mold inspectors and remediators are equipped with specialized knowledge and tools to ensure that the job is done safely and effectively. They can also provide you with a detailed report and advice on how to prevent future occurrences.

Remember, improper handling of mold can lead to health issues for yourself and your family members, particularly those with allergies or respiratory conditions. It's not just about aesthetics; it’s about safety.

In conclusion, while basic DIY cleaning might work for minor cases, given the appearance and smell of the mold behind your shower wall, it is advisable to seek professional help to avoid potential health risks and ensure a thorough solution.
