Attempting DIY removal in Adelphi 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 Adelphi property receives EPA-registered antimicrobial treatment specific to toxigenic species. The job closes with post-clearance air sampling and a written clearance report.

We were buying a home in Adelphi and mold showed up on the inspection report two days before closing. I called Koppers Waterproofing in a panic. They came out the next morning, knocked it out in 48 hours, and we had the clearance report in time for the lender. Deal closed. I've already recommended them to two friends in Adelphi.
My Adelphi restaurant was flagged for mold during a health inspection. Called Koppers Waterproofing that morning. Crew on-site by noon, affected prep area contained without shutting down the full kitchen, clean clearance report before my reinspection. Saved us from a week-long closure. They understood exactly what was at stake.
Two years of musty smell in our Adelphi basement we kept blaming on old construction. Finally tested it — significant mold behind the drywall. Koppers Waterproofing removed it, treated the framing, recommended dehumidification, did a 30-day follow-up test. Clean. Two years of guessing solved in one week.
Clear information before any Adelphi property owner commits to anything.

Yes — unconditionally on every Adelphi project.

Signs that warrant a professional Foundation Crack Repair inspection in your Adelphi property: visible dark spotting on walls, ceilings, or floors; persistent musty odor in bathrooms, basements, or after water events; allergy-like symptoms among occupants that improve when leaving the building; past water damage not dried within 24 to 48 hours; relative humidity consistently above 60%. Any of these in your Adelphi home or business warrants a call to +1-866-476-1348. Early inspection is almost always less expensive than delayed remediation.
Standard homeowners insurance in Adelphi 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 Adelphi insurance carrier submission: inspection reports, certified lab analysis, photo documentation, remediation scope, and clearance reports. We communicate with your Adelphi adjuster directly when that helps the process.
Mold recurrence in Adelphi properties almost always traces to an unresolved moisture source — not to failed remediation work. We address this directly by identifying and documenting the cause on every project. Call +1-866-476-1348 to learn more about our Adelphi prevention services.
