We could smell something musty in the hallway closet but never found anything. Turned out to be a slow leak behind the wall from an old pipe. They found it in under an hour and the smell was gone once the work was done.

Good to know
Mold Odor Removal in Clarkson Valley, MO: common questions
Can there be mold if I can't see any?
Yes. Mold often grows inside wall cavities, under flooring, or in ductwork long before it becomes visible on a surface. A persistent musty smell is one of the most common signs of hidden growth.
How do you find odor without visible mold?
We walk the space to locate where the smell is strongest, then use a moisture meter to check nearby walls, floors, and baseboards. If needed, we open a small access point to confirm what's happening inside a cavity.
Is a musty smell in my basement normal for Missouri homes?
A faint concrete smell can be normal, but a strong, persistent musty odor usually isn't. It's worth having checked, especially in basements near foundations that see spring runoff.
How soon can you start mold odor removal in Clarkson Valley?
We answer our line 24/7 and can usually reach a Clarkson Valley home the same day you call, sooner for an active leak.
Will air fresheners or ozone machines fix the smell?
They can mask odor temporarily but don't address the source. If mold or trapped moisture is causing the smell, it will typically return once the treatment wears off.
What if you can't find a source?
It happens occasionally, especially with faint or intermittent smells. We'll tell you honestly if we don't find active moisture or mold rather than recommending unnecessary removal.
Do I need to leave my Clarkson Valley home during the work?
Usually no. We seal the work area under negative air, so most of the Clarkson Valley home stays livable. For larger jobs we will tell you if it is better to step out for a day.
Do you serve Clarkson Valley?
Yes. We cover all of Clarkson Valley, including Ellisville, Ballwin, Chesterfield, and the rest of the Clarkson Valley area. We are based in Glencoe, about 10 minutes from our Glencoe base, and answer our own phone around the clock.
