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.

Good to know
Humidity & Condensation Mold Control in Downers Grove, 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.
How soon can you start humidity & condensation mold control in Downers Grove?
We answer our line 24/7 and can usually reach a Downers Grove home the same day you call, sooner for an active leak.
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 do you keep the mold from coming back after humidity & condensation mold control?
We fix the moisture source first, not just the mold, then dry the structure and recheck it. That is what keeps mold from returning to a Downers Grove home.
Do you serve Downers Grove?
Yes. We cover all of Downers Grove, including Westmont, Lisle, Oakbrook Terrace, and the rest of the Downers Grove area. We are based in Clarendon Hills, about 5 minutes from our Clarendon Hills base, and answer our own phone around the clock.
