Cost to treat mold behind wardrobe in Discovery Gardens?« Back to Previous Page

We've lived here for 2 years and just noticed a bunch of black spots spreading on the wall behind our bedroom wardrobe in Discovery Gardens. I'm worried it's mold, probably from the AC unit. I have no idea if this is a simple clean-up job or something major that needs a professional team – can anyone give me a rough idea of what it might cost to get this properly inspected and treated?

In Discovery Gardens, that's almost certainly mold caused by condensation from your AC unit meeting the warm, humid air. The wall behind furniture is a classic spot for it, as airflow is restricted.

For a proper assessment, you need to identify the moisture source and the mold type. Surface cleaning with a vinegar or diluted bleach solution can work for very small, recent patches (under one square meter). However, if it's spread behind the wardrobe and possibly into the drywall, a professional inspection is strongly recommended to prevent recurrence and check for hidden growth.

Treatment cost isn't fixed; it depends entirely on the extent of the damage. Factors include the square footage affected, whether the drywall or insulation needs replacement, and if the AC drain line or unit itself is the source of the moisture. A reputable provider will first conduct a visual assessment and likely recommend air and surface sampling to identify the species, which dictates the remediation protocol. Always request a detailed scope of work and cost breakdown after the initial inspection.
