Good to know
Mold After Plumbing Leak in O'Fallon, IL: common questions
How do I know if a leak caused mold?
A musty smell near a fixture, discolored cabinet backing, or soft subfloor near a sink or toilet are common signs mold has started after a leak.
Can mold grow from a leak I already fixed?
Yes, if the cavity stayed wet long enough before the repair, mold can already be established even though the leak itself is resolved.
How long does mold after a plumbing leak take to remediate?
It depends on how far the moisture traveled, but most single-fixture leaks are contained and dried within a few days once we start.
Do I need to leave my O'Fallon home during the work?
Usually no. We seal the work area under negative air, so most of the O'Fallon home stays livable. For larger jobs we will tell you if it is better to step out for a day.
Should I fix the leak myself before calling?
If you can safely shut off water to the fixture, that helps limit further damage, but leave the moldy material alone and let us assess it before cleanup begins.
Do you work with my plumber?
We coordinate with plumbers regularly so the leak repair and the mold remediation happen in the right order.
How do you keep the mold from coming back after mold after plumbing leak?
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 O'Fallon home.

Yes. We cover all of O'Fallon, including Shiloh, Fairview Heights, Scott Air Force Base, and the rest of the O'Fallon area. We are based in Glen Carbon, about 20 minutes from our Glen Carbon base, and answer our own phone around the clock.
