We noticed spotting on the drywall in a corner of our living room and figured it was just surface dirt. It had already gotten into the wall cavity. They mapped out exactly how far it went before cutting anything, which I appreciated.

Good to know
Wall & Drywall Mold Removal in Marengo, IL: common questions
Can I paint over mold on drywall?
No. Painting over mold traps it and doesn't address the growth inside the drywall paper. It will usually resurface, sometimes worse, and can spread further inside the wall in the meantime.
Is exterior wall mold different from interior wall mold?
The removal process is similar, but exterior wall mold is more often caused by condensation from a temperature difference, while interior wall mold usually points to a plumbing leak or moisture intrusion from an adjacent space.
What if the mold has reached the wall studs?
Lightly affected framing can often be cleaned and treated in place. If it's gone deeper, we'll walk you through what's needed before closing the wall back up.
How do you keep the mold from coming back after wall & drywall 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 Marengo home.
How much drywall will you remove?
We use moisture readings to define the affected boundary and cut along stud lines, so the removal matches the actual problem rather than an oversized guess.
Will you replace the drywall too?
We handle removal, drying, and can coordinate the drywall rebuild and texture matching as part of the project.
Do I need to leave my Marengo home during the work?
Usually no. We seal the work area under negative air, so most of the Marengo home stays livable. For larger jobs we will tell you if it is better to step out for a day.
Do you serve Marengo?
Yes. We cover all of Marengo, including Indian Trails, Union, Garden Prairie, and the rest of the Marengo area. We are based in Genoa, about 20 minutes from our Genoa base, and answer our own phone around the clock.
