We earn these reviews by doing exactly what we said we'd do.
We were buying a home in Gresham 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 Gresham.
My Gresham 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.
Two years of musty smell in our Gresham basement we kept blaming on old construction. Finally tested it — significant mold behind the drywall. Koppers Waterproofing removed it, treated the framing, recommended dehumidification, did a 30-day follow-up test. Clean. Two years of guessing solved in one week.
