AC mold in JVC villa: DIY or professional removal?« Back to Previous Page

That leak has created the perfect conditions for mold growth, and the visible patch is likely just the surface manifestation. In Dubai's high humidity, the moisture has almost certainly wicked into the drywall and possibly the insulation behind it, creating a larger hidden problem.

For a situation involving structural materials like drywall, professional assessment is strongly recommended over a DIY approach. Spraying the surface only addresses what you can see, not the root cause or the contaminated material behind it. Disturbing it yourself can also aerosolize spores throughout the room. A proper remediation involves identifying the full extent of the moisture damage, safely removing and disposing of affected porous materials like drywall, and HEPA-vacuuming the area to capture spores.

The cost for a professional job isn't based solely on the small visible area but on the scope of work required to fix the leak, remove all contaminated materials, and ensure the space is properly dried. For a localized leak from an AC unit impacting a section of wall, you are generally looking at a project that is more involved than a simple surface clean but not a full-home remediation. The most accurate way to understand the cost is to request an onsite assessment from a company that can provide a scope of work based on their findings.
