We had a musty smell in the hallway for months with nothing visible anywhere. The team used a camera to check inside the wall and found mold from an old leak we didn't even know about. Glad we finally had it checked.

Reviews
Rated 4.9 by Naperville-area neighbors
Called about a musty smell and they walked me through every step before starting. The area was contained properly and the odor was gone when they finished.
They found mold under the flooring that two other companies missed. Thorough and skilled.

Good to know
Hidden Mold Remediation in Naperville, IL: common questions
I smell mold but can't see any. What should I do?
A persistent musty smell with no visible source is worth having inspected. We use moisture meters and cameras to locate hidden mold without unnecessary demolition.
Can hidden mold make a home smell musty without being visible?
Yes, mold growing inside a wall cavity, under flooring, or behind a cabinet can produce a noticeable smell well before it becomes visible on a surface.
Is hidden mold more dangerous than visible mold?
It isn't inherently more dangerous, but it often goes untreated longer since nobody knows it's there, which can let it spread further before it's addressed.
Is the hidden mold remediation you do in Naperville to a real standard?
Yes. Our crew follows the IICRC S520 standard for mold remediation, the same framework insurers and inspectors recognize across DuPage County.
Will you have to cut open my walls?
Sometimes a small opening is needed to confirm and access hidden mold, but we always try to locate it first with non-invasive tools to keep the opening as small as possible.
How do I know if past water damage left mold behind?
If an area was wet in the past and the smell or discoloration returned later, it's a strong indicator that moisture remained trapped inside a cavity.
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.
Do you serve Naperville?
Yes. We cover all of Naperville, including Warrenville, Lisle, Winfield, and the rest of the Naperville area. We are based in Clarendon Hills, about 15 minutes from our Clarendon Hills base, and answer our own phone around the clock.
