Mold removal cost and DIY advice for JVC?« Back to Previous Page

That black splotch pattern spreading from a leaking AC unit is a classic sign of a moisture problem that needs immediate attention. In Dubai's high humidity, this creates an ideal environment for mold growth, and it's likely spreading inside the wall cavity behind the wallpaper.

For a situation involving a water leak and visible spread, hiring a professional is strongly recommended. This is not a simple surface cleaning job. Proper remediation involves identifying and stopping the water source (the AC leak), containing the affected area to prevent spores from spreading during work, safely removing the contaminated porous materials like drywall and wallpaper, and HEPA-vacuuming the area. Attempting this yourself without proper equipment and containment can cross-contaminate other areas of your apartment.

The cost for professional remediation isn't fixed; it's based on the square footage of the affected area and how deeply it has penetrated the structure. Since the mold is on the wallpaper and the wall is wet, the drywall behind it is almost certainly compromised. You will need to request an inspection and a detailed assessment to get an accurate scope of work and associated cost. Any reputable provider should offer this inspection first, outlining the exact process and the testing—often involving a pre- and post-remediation lab analysis—to verify the environment has been returned to a normal fungal ecology.

For context, Dubai Municipality has guidelines on indoor air quality, and proper remediation aligns with international standards like IICRC S520, which reputable local companies follow. Start by getting your AC unit serviced to stop the leak, then contact a certified mold assessment company for an inspection. They will determine the full extent and provide a remediation plan.
