AC mold in bedroom: DIY bleach or call a professional?« Back to Previous Page

A leak from an AC unit in a Jumeirah apartment almost certainly indicates an issue with the drain line or condensation pan, which creates the constant moisture source mold needs to thrive. The visible patches and increasing smell suggest it's actively growing, and what you see on the wall is likely just a fraction of the colony, which may extend inside the wall cavity or within the AC unit itself.

Using supermarket bleach is not recommended. Bleach is mostly water, which can feed mold growth deeper in porous materials like drywall. It only bleaches the surface and does not address the root moisture problem. The chlorine also evaporates quickly, leaving no residual protection, and its fumes can be particularly irritating in a poorly ventilated bedroom.

Given the leak, the strong odor, and Dubai's high ambient humidity that prevents materials from drying naturally, a professional assessment is the prudent course. They will identify and rectify the source of the water leak first. Proper remediation involves containing the area, removing affected porous materials if necessary, and using specialized antimicrobials. A company with its own microbiology lab can then take air and surface samples to verify the species and confirm the spore count has returned to a normal level, ensuring the problem is resolved and not just hidden.

The cost for this will depend entirely on the extent of the hidden damage. A small, contained patch may be a straightforward fix, while a larger infestation inside the wall will require more work. Reputable providers will typically perform a detailed inspection first and provide a scope of work with a clear breakdown of costs before any remediation begins.
