Should I clean damp moldy wall myself or call a pro?« Back to Previous Page

That damp, cold wall with black speckles is a classic sign of condensation mould, extremely common in Dubai apartments due to the high humidity and constant air conditioning creating cold surfaces. Cleaning it yourself with bleach is not recommended; it only bleaches the visible colour and doesn't kill the root structure, often causing it to return stronger while exposing you to harsh fumes in a confined space.

For a small, surface-level patch, you can try cleaning it with a dedicated mould remover or a solution of white vinegar and water, wearing an N95 mask and gloves. However, the dampness behind the wardrobe suggests a more persistent moisture issue, likely from condensation on the cold wall or a potential hidden leak. Simply cleaning the surface will not solve the underlying problem.

Given the location in your bedroom and the potential for spores to spread, a professional assessment is strongly advised. They use moisture meters and thermal cameras to locate the exact moisture source—whether it's inadequate insulation, a leaking pipe, or simply severe condensation—which is the only way to implement a permanent fix. The cost for an inspection is typically less than a full remediation and will give you a clear picture of the necessary steps, saving you money on ineffective DIY attempts in the long run.
