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

That's exactly how it should work.
I manage commercial properties in Harrietta and I've dealt with enough remediation contractors to know the difference.

Called Koppers Waterproofing for a Harrietta 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.

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