After removal, every exposed surface in your Grand Marsh property receives EPA-registered antimicrobial treatment specific to toxigenic species. The job closes with post-clearance air sampling and a written clearance report.

That's exactly how it should work.

Two years of musty smell in our Grand Marsh basement we kept blaming on old construction. Finally tested it — significant mold behind the drywall.
