They require full containment, PPE-equipped removal, and HEPA air scrubbing throughout the entire work period. Our Annandale black mold protocol starts with confirmed species identification through certified lab analysis — not a visual assumption.

Homeowners and business operators in Annandale — real testimonials from people who called Koppers Waterproofing when mold became a real problem.
We were buying a home in Annandale 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 Annandale.
My Annandale 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 Annandale 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.
