We kept getting mold on the same bedroom window every winter and finally had it looked at properly. Turned out it was a ventilation issue as much as the window itself, and the team explained exactly what was happening before doing the cleanup.

Mold on window frames, drywall, or ductwork is cleaned or removed depending on the surface and extent.

Humidity & Condensation Mold Control in Dupo, IL: common questions
Can Illinois's dry climate still have a mold problem?
Yes, condensation from temperature differences, humidifiers, or poor ventilation can create localized humid spots even in a generally dry climate.
Can a humidifier cause mold?
Yes, evaporative coolers add significant moisture to indoor air, and if it isn't managed well it can lead to condensation and mold near ducts and vents.
Do you check ductwork for condensation mold?
Yes, we inspect ductwork and register boots since sweating ducts in a crawl space or attic are a common and often overlooked source.
Is the humidity & condensation mold control you do in Dupo to a real standard?
Yes. Our crew follows the IICRC S520 standard for mold remediation, the same framework insurers and inspectors recognize across Saint Clair County.
Why does mold keep coming back on my window sill?
If condensation keeps forming, wiping the mold away is only a temporary fix. The underlying humidity or insulation issue needs to be addressed.
Is condensation mold less serious than mold from a flood?
It's typically smaller in scope, but it can still spread if left unaddressed and the underlying humidity issue is not corrected.
