ac leak causing mold: professional cost and necessity?« Back to Previous Page

Yes, you should hire a professional for this. A condensation leak inside a wall cavity is a serious issue that requires remediation, not just surface cleaning. The black mold spreading on your baseboard is a visible sign of a much larger, hidden problem within the wall. In Dubai's high humidity, this mold will continue to grow rapidly if the moisture source isn't permanently stopped.

The realistic price to fix this properly is not a single figure, as it breaks down into two separate professional services. First, an HVAC technician must locate and repair the condensation drain line leak or insulation failure causing the water intrusion. This is a non-negotiable first step; without fixing the leak, mold will return. Second, a mold remediation specialist must assess the damage inside the wall, safely remove the contaminated materials like drywall and insulation, and treat the area to prevent regrowth. The final cost is entirely dependent on the extent of the water damage and how far the mold has spread, which is impossible to know without opening the wall.

For an accurate assessment and quote, you need a professional inspection. Reputable firms in Dubai use borescopes to inspect inside walls and provide a detailed scope of work and pricing based on the actual damage found, not guesswork. Always request a detailed quote that separates the cost of leak repair from the mold remediation work.
