Dennison homeowners finding mold in their home need three things immediately: a complete picture of the scope, a clear binding price, and fast professional action. Koppers Waterproofing delivers all three — thermal imaging, air sampling, written estimate, and IICRC S520 protocol from the first inspection through final air clearance testing.
After inspection, you receive a complete written itemized estimate for your Dennison project. The process follows IICRC S520 from containment setup through antimicrobial surface treatment and post-clearance air testing.
We've worked in Dennison area restaurants, medical facilities, retail spaces, warehouses, and multi-unit residential buildings. HVAC-distributed mold is assessed on every Dennison commercial inspection as standard.
Large Dennison commercial projects get a dedicated project manager, daily updates, and complete documentation for insurance carriers and regulatory bodies.
Not sure if your Dennison property has an actionable mold problem? Our inspection delivers documented answers — calibrated air sampling through certified labs, thermal imaging, moisture mapping, and surface swabs to build a complete picture before any remediation is recommended.
Pre-sale mold inspections in Dennison 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 Dennison, IL.
Toxigenic mold species — particularly Stachybotrys — appear in Dennison 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 Dennison black mold protocol starts with confirmed species identification through certified lab analysis — not a visual assumption.
After removal, every exposed surface in your Dennison property receives EPA-registered antimicrobial treatment specific to toxigenic species. The job closes with post-clearance air sampling and a written clearance report.
Prevention services for Dennison properties include crawl space encapsulation, vapor barrier installation, dehumidification system design, ventilation assessments, and structural moisture intrusion identification.
Our optional maintenance program for Dennison customers includes 30-day and 90-day follow-up air quality checks — documenting that the property remains clear after remediation closes.

Found black mold in our Dennison home after a hidden plumbing leak. Called Koppers Waterproofing at 9 PM expecting voicemail. Someone answered immediately. Crew was at our Dennison property the next morning with a written estimate before they looked at anything. Done in 48 hours, air clearance test passed, price matched exactly what they quoted. That's exactly how it should work.
I manage commercial properties in Dennison and I've dealt with enough remediation contractors to know the difference.

Two years of musty smell in our Dennison 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.

Signs that warrant a professional Foundation Crack Repair inspection in your Dennison property: visible dark spotting on walls, ceilings, or floors; persistent musty odor in bathrooms, basements, or after water events; allergy-like symptoms among occupants that improve when leaving the building; past water damage not dried within 24 to 48 hours; relative humidity consistently above 60%. Any of these in your Dennison home or business warrants a call to +1-866-476-1348. Early inspection is almost always less expensive than delayed remediation.
Standard homeowners insurance in Dennison typically covers mold remediation resulting from a covered sudden event — burst pipe, storm damage, appliance failure.

We communicate with your Dennison adjuster directly when that helps the process.
Our Dennison remediation is designed to last — and we back it with a written satisfaction guarantee. For customers who want ongoing documented verification, our maintenance program provides follow-up air quality checks at 30 and 90 days.
