Harleysville 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 Harleysville project. The process follows IICRC S520 from containment setup through antimicrobial surface treatment and post-clearance air testing.

Toxigenic mold species — particularly Stachybotrys — appear in Harleysville 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 Harleysville black mold protocol starts with confirmed species identification through certified lab analysis — not a visual assumption.
After removal, every exposed surface in your Harleysville 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 Harleysville's climate requires addressing the moisture source directly. Every Koppers Waterproofing project in Harleysville includes moisture source identification and documented prevention recommendations as standard deliverables.
Our optional maintenance program for Harleysville customers includes 30-day and 90-day follow-up air quality checks — documenting that the property remains clear after remediation closes.

Called Koppers Waterproofing for a Harleysville crawl space inspection after heavy rain flooding.
