We had no idea our bathroom fan was venting straight into the attic until they pointed it out. The mold on the sheathing was cleaned up and they explained exactly why it kept coming back after we'd tried dealing with it ourselves.

Good to know
Attic Mold Removal in Naperville, IL: common questions
How do I know if I have attic mold?
Most homeowners don't see it directly since attics aren't visited often. Signs include a musty smell near the attic access, dark staining you notice while up there for another reason, or a bathroom fan that seems to run into open space rather than outside.
Do you replace all the insulation?
Only the insulation that's wet, compressed, or contaminated. Insulation outside the affected area usually doesn't need to be touched.
Will you check my attic ventilation even if I don't have visible mold?
Yes, if you're concerned about a musty smell or just want a general check, we can inspect ventilation and moisture levels without assuming there's already a problem.
Do I need to leave my Naperville home during the work?
Usually no. We seal the work area under negative air, so most of the Naperville home stays livable. For larger jobs we will tell you if it is better to step out for a day.
Is attic mold from a roof leak different to treat than mold from ventilation?
The removal process is similar, but the fix afterward is different. A roof leak needs roofing repair to stop future water intrusion; a ventilation issue needs the exhaust routing or soffit airflow corrected.
Can attic mold affect the air quality in my house?
It can, especially if there's airflow between the attic and living space through gaps, can lights, or the attic access hatch. That's part of why we contain the access point during work.
How soon can you start attic mold removal in Naperville?
We answer our line 24/7 and can usually reach a Naperville home the same day you call, sooner for an active leak.
Do you serve Naperville?
Yes. We cover all of Naperville, including Warrenville, Lisle, Woodridge, and the rest of the Naperville area. We are based in Winfield, about 10 minutes from our Winfield base, and answer our own phone around the clock.
