Attempting DIY removal in West Chester without containment is one of the most common ways a localized problem becomes a building-wide crisis. Our protocol prevents that.
After removal, every exposed surface in your West Chester property receives EPA-registered antimicrobial treatment specific to toxigenic species. The job closes with post-clearance air sampling and a written clearance report.
Remediation removes the active colony. Prevention keeps it from coming back — which in West Chester's seasonal weather environment requires addressing the moisture source directly.
