Mold in AC closet: professional cost or DIY fix?« Back to Previous Page

The AC in my apartment in Jumeirah seems to be leaking a bit of water into the closet in the hallway, and now I’m spotting black mold on the back wall and on some of our shoes. With the humidity rising again, I’m worried it's just going to get worse. What’s the ballpark cost for a professional mold remediation service for a small area like this, and is it something I can realistically tackle myself with products from ACE?

Hey there, that's a super common issue here in Jumeirah, especially with the humidity ramping up. The water leak from the AC is the root cause – that condensate line might be clogged or the drain pan is cracked. The black mold you're seeing is likely Stachybotrys or Cladosporium, which thrive in the constant dampness from that leak.

For a small closet area, a professional remediation job typically ranges from AED 1,500 to AED 3,500. This usually includes containment of the area, HEPA vacuuming, antimicrobial treatment, and addressing the source of the moisture (the AC issue). It's not just about wiping it away; it's about ensuring the spores are removed and the conditions for regrowth are eliminated. We always recommend a pro inspection because what you see on the surface is often just the tip of the iceberg, and improper handling can aerosolize spores and spread them.

While you might find mold-killing sprays at ACE, a DIY fix is a big risk. You might clean the visible growth but miss the root cause and the hidden colonies within the wall cavity. This is a guaranteed recurrence. Plus, in multi-unit buildings, there can be liability concerns if mishandled remediation affects other apartments.

Get that AC unit serviced IMMEDIATELY to stop the water intrusion. For a proper assessment and a firm quote, it's best to have a specialist come out. Give us a call at 800-MOLDS (800-66537) or email hello@saniservice.com and we can schedule a visit.
