We were buying a home in Saint Louis 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 Saint Louis.
My Saint Louis 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 Saint Louis 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.

Signs that warrant a professional Interior Drainage System inspection in your Saint Louis 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 Saint Louis home or business warrants a call to +1-866-476-1348. Early inspection is almost always less expensive than delayed remediation.

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.

We identify the cause, document it, and provide specific prevention recommendations for your Saint Louis property type. Our optional maintenance program includes 30-day and 90-day follow-up air quality checks for Saint Louis customers.
