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.
Large Mentor commercial projects get a dedicated project manager, daily updates, and complete documentation for insurance carriers and regulatory bodies.
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.
Attempting DIY removal in Mentor without containment is one of the most common ways a localized problem becomes a building-wide crisis. Our protocol prevents that.
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.
Remediation removes the active colony. Prevention keeps it from coming back — which in Mentor's climate requires addressing the moisture source directly. Every Koppers Waterproofing project in Mentor includes moisture source identification and documented prevention recommendations as standard deliverables.
Our optional maintenance program for Mentor customers includes 30-day and 90-day follow-up air quality checks — documenting that the property remains clear after remediation closes.

We earn these reviews by doing exactly what we said we'd do.
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.
I manage commercial properties in Mentor and I've dealt with enough remediation contractors to know the difference. Koppers Waterproofing knows the protocol — contained the Mentor property, kept adjacent tenants operational, complete insurance documentation at close. They're the only company I call for Mentor commercial remediation now.
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.
Clear information before any Mentor property owner commits to anything.
For emergency calls in Mentor, we dispatch immediately with a goal of same-day arrival.

Signs that warrant a professional Wet Basement Repair inspection in your Mentor 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 Mentor 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 Mentor typically covers mold remediation resulting from a covered sudden event — burst pipe, storm damage, appliance failure.

Koppers Waterproofing provides complete documentation packages structured for Mentor insurance carrier submission: inspection reports, certified lab analysis, photo documentation, remediation scope, and clearance reports. We communicate with your Mentor adjuster directly when that helps the process.
Our Mentor 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.
