Our basement window well flooded during a summer storm and water got into the finished basement. The crew came out quickly, pulled the wet drywall and carpet pad, and had everything dried out within a few days.

Thorough inspection and a fair quote. They explained the lab results in plain words and never pushed anything on us.

No more allergy symptoms since they cleaned the mold from our HVAC and bedroom walls.

Our process

Our flood & storm mold cleanup process in O'Fallon, IL

Inspect

We assess how far floodwater traveled and which materials absorbed it, room by room.

Contain

We section off affected areas so cleanup work doesn't spread contamination to dry parts of the home.

Remove

Water-damaged drywall, flooring, and insulation are removed, since flood water often can't be fully sanitized in place.

Dry

Industrial air movers and dehumidifiers dry the structure to normal moisture levels.

Verify

We confirm dryness and treat remaining surfaces before the job is complete.

Local knowledge

Flood & Storm Mold Cleanup for O'Fallon, IL homes

Flood & Storm Mold Cleanup in O'Fallon tends to start the same way mold does across Saint Clair County: older O'Fallon homes with finished basements and low ventilation that let damp air linger. When that moisture sits for even a day or two, mold takes hold, and that is when homeowners from Shiloh, Fairview Heights, Scott Air Force Base and the rest of O'Fallon call us.

We handle flood & storm mold cleanup for O'Fallon the right way. We find and fix the moisture source first, because mold always returns if the water problem is left behind, then we contain the area and remove the mold safely.

Our team is based in Glen Carbon, about 20 minutes from our Glen Carbon base, so we can usually reach a O'Fallon home the same day. Our methods follow public guidance from the EPA and the CDC on handling indoor mold safely.

Good to know

Flood & Storm Mold Cleanup in O'Fallon, IL: common questions

How fast should I call after a flood?

As soon as it's safe. Mold risk climbs quickly once materials stay wet, so the sooner cleanup starts, the more of the structure can typically be saved.

Can I stay in my home during flood mold cleanup?

It depends on how much of the home was affected. We'll walk you through what areas need to be closed off during the work.

Will my homeowners policy cover storm-related mold?

Coverage depends on your specific policy and the source of the water. We document everything thoroughly to support your claim.

Is the flood & storm mold cleanup you do in O'Fallon to a real standard?

Yes. Our crew follows the IICRC S520 standard for mold remediation, the same framework insurers and inspectors recognize across Saint Clair County.

Is flood water mold cleanup different from a regular leak?

Yes, flood water can carry contaminants, so porous materials that got wet are often removed rather than dried and reused.

Do you handle basement flooding from spring rain?

Yes, spring runoff and spring rain flooding into basements and crawl spaces is common in Glen Carbon and we handle it regularly.

How do you keep the mold from coming back after flood & storm mold cleanup?

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.

Do you serve O'Fallon?

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.
