Homeowners and business operators in Wilmette — real testimonials from people who called Koppers Waterproofing when mold became a real problem.
Found black mold in our Wilmette home after a hidden plumbing leak. Called Koppers Waterproofing at 9 PM expecting voicemail. Someone answered immediately. Crew was at our Wilmette 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 Wilmette 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 Wilmette 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.
