Highly recommended! Jason promptly came out to help ease our worry from a slow leak we found in our shower. He was VERY honest and thorough. He determined we do not have a mold problem and didn’t try to sell us on something we didn’t need. I really can’t recommend this company enough.

Mold thrives in damp, humid environments. Common causes include water damage from flooding, roof leaks, plumbing issues, or poor ventilation. In Oswego, IL, basement moisture is a frequent culprit, especially in older homes. Mold can begin to develop within 24-48 hours of exposure to moisture, making prompt action critical. Left unchecked, it can lead to structural problems and costly repair bills—not to mention serious health concerns for those with respiratory issues or allergies.

We follow a detailed and proven approach to ensure complete mold remediation and restoration of your home or commercial property:
- • Inspection and Assessment: Our certified Applied Microbial Remediation Technicians will perform a thorough visual mold inspection, identifying the source of moisture and scope of contamination.
- • Containment: We isolate affected areas to prevent the spread of mold spores to other parts of your property.
- • HEPA Filtration: Using high-efficiency air scrubbers and vacuums with HEPA filters, we clean the air and remove airborne mold particles.
- • Safe Mold Removal: Our team uses effective antimicrobial solutions to eliminate mold colonies from surfaces, including walls, ceilings, and other areas of your home or business. Attempting to clean mold yourself using household cleaners may make the situation worse by releasing spores into the air.
- • Restoration: We restore the mold damaged areas to their original condition. Our restoration team ensures your space is clean, safe, and mold-free.
Sometimes, mold isn’t visible. If your property has a musty odor, experienced a leak, or if occupants are showing unexplained allergy-like symptoms, it’s time to get a mold inspection. We offer non-invasive, professional evaluations to test for the presence of mold contamination.

Accurate testing is essential for formulating a safe, effective remediation plan—especially when dealing with potentially toxic varieties like black mold (Stachybotrys chartarum). Early detection can help prevent or minimize expensive repair work and reduce health risks.

Brandon, Jacob, and Ricky were excellent. Very professional, clean, and knowledgeable. Kept us informed throughout the process and went above in maintaining a time sensitive completion deadline.

Our mold issue was discovered by our home buyer's inspector. Needless to say it was a very stressful situation given we could have lost the sale of our home. Brandon came in and was extremely helpful in explaining the process and making us feel at ease. Crew was exceptional; very courteous and efficient.

I am very happy with the services rendered by Cornerstone. From the minute I called to inquire they took immediate concern and came out asap. Ricky, Alex and Leo worked cautiously and with minimal disruption which was greatly appreciated given the fact that I have a 3 year old running around and a 3 month old baby. They went above and beyond to ensure everything was cleaned and in place before wrapping up. Thank you!
