How to stop AC leak and prevent mold in bedroom?« Back to Previous Page

The black spots are likely mold, and the AC leak is providing the constant moisture it needs to thrive. Dubai's high humidity, especially during summer, accelerates this process. First, address the water source immediately.

A clogged condensate drain line is the most common cause of AC leaks in Dubai apartments. Turn off the AC unit at the circuit breaker to stop the water flow. Soak up any standing water from the carpet completely and use a fan to dry the area rapidly. For the visible mold on the skirting board, a solution of white vinegar or a diluted bleach mixture (1 part bleach to 10 parts water) can clean non-porous surfaces, but this only addresses surface growth you can see.

To stop it for good, the leak must be professionally fixed and the hidden moisture in the carpet and padding must be identified. Mold roots can penetrate porous materials like drywall and carpet backing, which cleaning cannot reach. The damp carpet pad underneath is a prime breeding ground for hidden mold that will spread spores.

Given the leak has already affected building materials, a professional inspection is recommended. They can use moisture meters to find all wet areas and recommend remediation, which often involves removing and replacing the affected skirting board and section of carpet to prevent regrowth. After fixing the leak and removing the contaminated materials, ensuring the area is thoroughly dried with industrial air movers is critical before any repairs are made. For persistent musty odors or health concerns, post-remediation testing by a microbiology lab can verify the spore count has returned to normal indoor levels.
