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

Called Koppers Waterproofing for a Cottage Grove 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 Cottage Grove 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 Cottage Grove home or business warrants a call to +1-866-476-1348. Early inspection is almost always less expensive than delayed remediation.
Standard homeowners insurance in Cottage Grove typically covers mold remediation resulting from a covered sudden event — burst pipe, storm damage, appliance failure.

We communicate with your Cottage Grove 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.

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