Is this a job for mold remediation? Cost?« Back to Previous Page

Based on your description, yes, this absolutely requires professional mold remediation. The combination of a persistent water leak from the AC, visible black microbial growth spreading on the wall, a damp smell, and allergy symptoms are all clear indicators of an active infestation that has moved beyond a simple surface issue.

In Dubai's climate, AC leaks are a primary cause of indoor mold. The constant high humidity and condensation create a perfect environment for mold to thrive inside wall cavities, which is likely happening behind your unit. The spreading black spots suggest the wallboard itself is contaminated and may need to be removed and replaced to properly address the root of the problem.

You should first have a certified mold inspector conduct an assessment. They will identify the moisture source (likely a clogged condensate drain line or faulty installation) and the extent of the hidden damage behind the wall using moisture meters and possibly a boroscope camera. The remediation process will involve containing the area, removing and disposing of contaminated porous materials like drywall and insulation, HEPA vacuuming, and antimicrobial treatment.

For cost, the price is entirely dependent on the scope of work. A small, contained job addressing a single wall section and the AC unit will be significantly less than a project requiring extensive demolition and reconstruction. The only way to get an accurate cost is to request an on-site assessment from a reputable company that provides detailed, lab-verified before-and-after testing. Avoid any company that gives a quote over the phone without seeing the damage.
