Our sump pump failed during a spring melt and we came home to a wet, musty basement. They pulled up the affected carpet and drywall, dried everything properly, and explained why our window well needed better drainage.

Great communication from the first call. They tested the air, handled the removal, and rechecked the space before signing off.
Happy with the remediation. Would have liked a quicker callback, but the crew did excellent work.
Our process
Our basement mold removal process in Upper Alton, IL
Inspect
We check foundation walls, the sump pit, and window wells for the moisture path, not just where mold is visible.
Contain
The basement is sealed off from the stairwell and upper floors before any material is disturbed.
Remove
Affected drywall, baseboard, and framing come out; masonry and concrete are cleaned and treated in place.
Dry
Air movers and dehumidifiers run until the space hits a safe moisture reading, not just until it looks dry.
Verify
We recheck moisture at the original problem spots before finishing, since basements can hide slow seepage.

Good to know
Basement Mold Removal in Upper Alton, IL: common questions
Is basement mold dangerous if the basement is unfinished?
Unfinished basements aren't automatically safer, they're just easier to inspect. Mold on concrete, framing, or stored items still needs to be addressed, especially if there's an active moisture source.
How do I know if my basement mold is from spring rain or a pipe leak?
Location is the biggest clue. Mold concentrated near foundation walls or window wells usually points to outside water; mold near a water heater, laundry area, or overhead pipe usually points to plumbing.
Do finished basements cost more to remediate?
Finished basements typically involve more removal, drywall, flooring, framing, which adds time and material compared to an unfinished space. We'll give you a specific scope after inspection.
How do you keep the mold from coming back after basement mold removal?
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 Upper Alton home.
Can you fix the water problem, not just remove mold?
We identify likely sources like foundation cracks or drainage issues and explain what we're seeing, but structural repairs like crack sealing or grading are outside our scope. We can point you toward what needs attention.
Will you move stored items out of the basement?
We'll help clear the immediate work area as needed. Heavily contaminated porous items like cardboard boxes or old carpet often can't be salvaged and we'll flag those before disposal.
Do I need to leave my Upper Alton home during the work?
Usually no. We seal the work area under negative air, so most of the Upper Alton home stays livable. For larger jobs we will tell you if it is better to step out for a day.
Do you serve Upper Alton?
Yes. We cover all of Upper Alton, including Alton, Godfrey, Rosewood Heights, and the rest of the Upper Alton area. We are based in East Alton, about 5 minutes from our East Alton base, and answer our own phone around the clock.
