Every Harpster emergency call gets same-day response as the operational standard. We don't send a technician to "assess and schedule" — our crews arrive with everything needed to begin containment and remediation on the first visit.

Harpster 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 Harpster project. The process follows IICRC S520 from containment setup through antimicrobial surface treatment and post-clearance air testing.
We've worked in Harpster area restaurants, medical facilities, retail spaces, warehouses, and multi-unit residential buildings. HVAC-distributed mold is assessed on every Harpster commercial inspection as standard.

We were buying a home in Harpster and mold showed up on the inspection report two days before closing. I called Koppers Waterproofing in a panic.

Two years of musty smell in our Harpster basement we kept blaming on old construction. Finally tested it — significant mold behind the drywall.
