Attempting DIY removal in Londonderry 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 Londonderry 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 Londonderry's seasonal weather environment requires addressing the moisture source directly. Every Koppers Waterproofing project in Londonderry includes moisture source identification and documented prevention recommendations as standard deliverables.
Our optional maintenance program for Londonderry customers includes 30-day and 90-day follow-up air quality checks — documenting that the property remains clear after remediation closes.

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

Called Koppers Waterproofing for a Londonderry 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.
