We find every affected area in your Sterling home — including growth hidden inside walls, beneath flooring, in crawl spaces, and in attic spaces. We document everything before quoting anything.

Pre-sale mold inspections in Sterling are among our most requested services — buyers, sellers, agents, and lenders need documented mold status before transactions close. Our reports meet both insurance submission and real estate disclosure requirements in Sterling, IL.
Toxigenic mold species — particularly Stachybotrys — appear in Sterling properties with histories of water damage or chronic moisture. They require full containment, PPE-equipped removal, and HEPA air scrubbing throughout the entire work period. Our Sterling black mold protocol starts with confirmed species identification through certified lab analysis — not a visual assumption.
After removal, every exposed surface in your Sterling property receives EPA-registered antimicrobial treatment specific to toxigenic species. The job closes with post-clearance air sampling and a written clearance report.
Remediation removes the active colony. Prevention keeps it from coming back — which in Sterling's humidity conditions requires addressing the moisture source directly. Every Koppers Waterproofing project in Sterling includes moisture source identification and documented prevention recommendations as standard deliverables.
Our optional maintenance program for Sterling customers includes 30-day and 90-day follow-up air quality checks — documenting that the property remains clear after remediation closes.

We were buying a home in Sterling and mold showed up on the inspection report two days before closing. I called Koppers Waterproofing in a panic. They came out the next morning, knocked it out in 48 hours, and we had the clearance report in time for the lender. Deal closed. I've already recommended them to two friends in Sterling.
I manage commercial properties in Sterling and I've dealt with enough remediation contractors to know the difference.

Two years of musty smell in our Sterling basement we kept blaming on old construction. Finally tested it — significant mold behind the drywall. Koppers Waterproofing removed it, treated the framing, recommended dehumidification, did a 30-day follow-up test. Clean. Two years of guessing solved in one week.
