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.

Inspect
We check humidity levels room by room and identify where condensation is forming and why.
Contain
We isolate any area with active mold growth before cleaning to avoid spreading spores.
Remove
Mold on window frames, drywall, or ductwork is cleaned or removed depending on the surface and extent.

Good to know
Humidity & Condensation Mold Control in Upper Alton, 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.
Do I need to leave my Upper Alton home during the work?
Usually no. We seal the work area under negative air, so most of the Upper Alton home stays livable. For larger jobs we will tell you if it is better to step out for a day.
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.
How soon can you start humidity & condensation mold control in Upper Alton?
We answer our line 24/7 and can usually reach a Upper Alton home the same day you call, sooner for an active leak.
