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.
