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 Rialto, CA: 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 California 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.
Do I need to leave my Rialto home during the work?
Usually no. We seal the work area under negative air, so most of the Rialto home stays livable. For larger jobs we will tell you if it is better to step out for a day.
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.
Is the mold odor removal you do in Rialto to a real standard?
Yes. Our crew follows the IICRC S520 standard for mold remediation, the same framework insurers and inspectors recognize across San Bernardino County.
Do you serve Rialto?
Yes. We cover all of Rialto, including Bloomington, Muscoy, Fontana, and the rest of the Rialto area. We are based in Grand Terrace, about 10 minutes from our Grand Terrace base, and answer our own phone around the clock.
