That's exactly how it should work.
My Gaithersburg restaurant was flagged for mold during a health inspection. Called Koppers Waterproofing that morning.

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

Standard homeowners insurance in Gaithersburg typically covers mold remediation resulting from a covered sudden event — burst pipe, storm damage, appliance failure. Mold from gradual neglect is generally excluded under MD policies. Koppers Waterproofing provides complete documentation packages structured for Gaithersburg insurance carrier submission: inspection reports, certified lab analysis, photo documentation, remediation scope, and clearance reports. We communicate with your Gaithersburg adjuster directly when that helps the process.
Properly performed remediation eliminates the active colony. Recurrence happens when the underlying moisture condition isn't resolved — because mold spores are naturally present in every indoor environment at trace levels. Every Koppers Waterproofing project in Gaithersburg addresses the moisture source as a required deliverable. We identify the cause, document it, and provide specific prevention recommendations for your Gaithersburg property type. Our optional maintenance program includes 30-day and 90-day follow-up air quality checks for Gaithersburg customers.
