Londonderry homeowners finding mold in their home need three things immediately: a complete picture of the scope, a clear binding price, and fast professional action.

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

That's exactly how it should work.

Koppers Waterproofing knows the protocol — contained the Londonderry property, kept adjacent tenants operational, complete insurance documentation at close. They're the only company I call for Londonderry commercial remediation now.
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.
