Merrillville properties face specific mold challenges driven by the seasonal moisture patterns common here. Our crews understand those conditions, which means faster accurate assessments and remediation that addresses the actual cause — not just the visible symptom.
Every Merrillville project starts the same way: a live person answers when you call, certified crew dispatched fast, thorough inspection with documented findings, written estimate you sign before work starts, and a job that closes only when post-clearance air testing confirms success.

Found black mold in our Merrillville home after a hidden plumbing leak. Called Koppers Waterproofing at 9 PM expecting voicemail. Someone answered immediately.

That's exactly how it should work.

They understood exactly what was at stake.
Two years of musty smell in our Merrillville basement we kept blaming on old construction. Finally tested it — significant mold behind the drywall.
