AC mold from leak: who to call first for safe removal?« Back to Previous Page

Call the AC maintenance team first. The leak is the source of the problem, and treating the mold without fixing it will lead to immediate regrowth. High-rises in the Marina often have complex AC systems where a clogged drain line or faulty insulation is the culprit, which building maintenance or your AC service provider must address.

For the mold itself, a small patch on concrete from a recent leak can often be treated with care. Wear an N95 mask and gloves. Scrub the area with a mixture of detergent and water, then disinfect with a solution of 1 part bleach to 10 parts water. Ensure the area is thoroughly dried with a fan afterward. However, if the mold covers more than one square meter, has a strong musty odor, or you have respiratory sensitivities, a professional indoor health service with microbial testing is strongly recommended to confirm the type and ensure safe, complete removal.

The combination of Dubai’s high humidity and constant AC use creates perfect conditions for mold to flourish within 24-48 hours of a water event. To prevent recurrence, insist the AC technicians not only fix the leak but also clean and sanitize the affected section of the air duct. A certified hygienization provider can perform this with documented before-and-after testing to verify the spores are gone.
