How to treat AC mold and check drain line?« Back to Previous Page

That's a classic Dubai problem you're describing, especially in Jumeirah with the sea air. The black spots on your skirting board are almost certainly mold, triggered by the AC condensate leak. Here's what you need to do immediately.

First, address the source: the AC unit. The drain line is the most likely culprit, often clogged with algae and dust, a common issue with our hard water and sandy environment. You can ask your landlord to have the building's maintenance team or an HVAC specialist check and flush the drain line. This is a landlord responsibility under typical tenancy contracts for maintaining AC units.

For the existing mold on the skirting board, if the area is small (less than 1 sqm), you can carefully clean it yourself. Wear an N95 mask and gloves! Don't just wipe it, as this spreads spores. Use a damp cloth with a solution of diluted white vinegar or a specialist mold-cleaning product, then ensure the area is dried completely with a fan. The carpet underneath is a bigger concern; the padding is likely soaked and will harbor mold. You may need to pull it back, dry it, and treat it.

However, if the leak has been ongoing or the discoloration is extensive, this is a sign of a deeper issue. Surface cleaning won't fix mold growing inside the wall cavity. For a proper assessment and remediation that meets Dubai Municipality's health and safety standards, a professional inspection is crucial. We use thermal imaging and moisture meters to find the full extent of the damage.
