When Mentor homeowners and business operators deal with mold, they need a company that knows the area, shows up fast, and gives them a binding written price before touching anything. That's Koppers Waterproofing. Our certified crews serve Mentor and surrounding OH communities with the same standard on every job — IICRC S520 protocol, written flat-rate pricing, and a satisfaction guarantee in writing.
Whether you're a Mentor homeowner dealing with a weekend mold discovery or a business operator who needs commercial remediation planned around your operating schedule, Koppers Waterproofing has the crew and protocol to handle it.
Here's the full Mentor service lineup.
Every Mentor 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 — Mentor emergency crews arrive with everything deployed on arrival. We stop the spread before it reaches unaffected areas.
Mentor 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 Mentor project. The process follows IICRC S520 from containment setup through antimicrobial surface treatment and post-clearance air testing.
We've worked in Mentor area restaurants, medical facilities, retail spaces, warehouses, and multi-unit residential buildings. HVAC-distributed mold is assessed on every Mentor commercial inspection as standard.
Post-remediation verification reports are provided on every Mentor commercial project — meeting insurance carrier, OSHA, and property management requirements. Call +1-866-476-1348 for a Mentor commercial site assessment.
If inspection finds no actionable issue in your Mentor property, we tell you that honestly. We don't manufacture work that isn't needed.
Pre-sale mold inspections in Mentor 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 Mentor, OH.
Toxigenic mold species — particularly Stachybotrys — appear in Mentor 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 Mentor black mold protocol starts with confirmed species identification through certified lab analysis — not a visual assumption.
After removal, every exposed surface in your Mentor 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 Mentor properties include crawl space encapsulation, vapor barrier installation, dehumidification system design, ventilation assessments, and structural moisture intrusion identification.

Homeowners and business operators in Mentor — real testimonials from people who called Koppers Waterproofing when mold became a real problem.
We were buying a home in Mentor 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 Mentor.
My Mentor 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 Mentor 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.
