Here's the full Clarkston service lineup.
Every Clarkston 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.
HEPA air scrubbers, negative pressure containment, industrial dehumidifiers, antimicrobial supplies — Clarkston emergency crews arrive with everything deployed on arrival. We stop the spread before it reaches unaffected areas.
Clarkston 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.
We coordinate with homeowners insurance carriers in Clarkston when situations qualify. Documentation is prepared for carrier submission from day one — inspection reports, lab results, photo documentation, remediation scope, and clearance reports.
We've worked in Clarkston area restaurants, medical facilities, retail spaces, warehouses, and multi-unit residential buildings. HVAC-distributed mold is assessed on every Clarkston commercial inspection as standard.

Not sure if your Clarkston 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 Clarkston 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 Clarkston, WA.
Toxigenic mold species — particularly Stachybotrys — appear in Clarkston 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 Clarkston black mold protocol starts with confirmed species identification through certified lab analysis — not a visual assumption.
After removal, every exposed surface in your Clarkston property receives EPA-registered antimicrobial treatment specific to toxigenic species. The job closes with post-clearance air sampling and a written clearance report.

Found black mold in our Clarkston home after a hidden plumbing leak. Called Koppers Waterproofing at 9 PM expecting voicemail. Someone answered immediately. Crew was at our Clarkston 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.
My Clarkston restaurant was flagged for mold during a health inspection. Called Koppers Waterproofing that morning. Crew on-site by noon, affected prep area contained without shutting down the full kitchen, clean clearance report before my reinspection. Saved us from a week-long closure. They understood exactly what was at stake.
Called Koppers Waterproofing for a Clarkston crawl space inspection after heavy rain flooding. They found early-stage mold before it spread, treated it, encapsulated the crawl space, and the follow-up test was clean. Catching it early saved me from a much bigger remediation cost. Should have scheduled an inspection sooner.
