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

Standard homeowners insurance in Sumner typically covers mold remediation resulting from a covered sudden event — burst pipe, storm damage, appliance failure. Mold from gradual neglect is generally excluded under MI policies. Koppers Waterproofing provides complete documentation packages structured for Sumner insurance carrier submission: inspection reports, certified lab analysis, photo documentation, remediation scope, and clearance reports. We communicate with your Sumner adjuster directly when that helps the process.
Properly performed remediation eliminates the active colony. Recurrence happens when the underlying moisture condition isn't resolved — because mold spores are naturally present in every indoor environment at trace levels.
