Mold from AC leak: call professional for removal cost?« Back to Previous Page

Yes, call a professional. A recurring black mold patch from an AC leak is a serious issue that requires more than surface cleaning. The leak has likely saturated the wall's internal structure, creating a hidden reservoir of moisture that vinegar cannot address. In Dubai's high humidity, this mold will continue to return and spread until both the water source is fixed and the contaminated materials are properly remediated.

For a problem of this scale, the process should involve a professional inspection to identify the exact extent of the water damage and mold growth inside the wall cavity. Reputable remediation follows a strict protocol: isolating the area to prevent spore spread, safely removing the contaminated wallpaper and any affected drywall or insulation, HEPA vacuuming, and applying professional-grade antimicrobial solutions. Crucially, the AC leak itself must be repaired by an HVAC technician to prevent immediate recurrence.

Cost is variable and depends entirely on the scope of work—primarily how much wall material must be removed and replaced, and whether the AC repair is included. In Dubai, you should expect a higher cost for quality work that includes proper containment, disposal, and verification of success. The most significant factor is the structural damage; the wall repair itself often constitutes a major portion of the final expense. Always request a detailed, on-site assessment and a written quote that breaks down the inspection, remediation, and repair components. Ask if the company can provide post-remediation verification to confirm the environment has been returned to a normal fungal ecology.
