Mold remediation built for Georgetown
If you're in a Georgetown rowhouse, you're living in one of the oldest buildings in the country — many of these Federal-style homes date to the late 1700s and early 1800s, built decades before anyone thought about a foundation waterproofing membrane, often straight onto Potomac floodplain clay. If your below-grade room has a moisture problem, it's working against 200+ years of settling, not something you did wrong.
Because most of Georgetown sits in a federally designated historic district, you can't just have a contractor repoint the brick, swap a window, or alter a basement entrance — that work goes through the U.S. Commission of Fine Arts and DC's Old Georgetown Board first. It's worth knowing that up front, because it adds real time to any remediation that touches the outside of the building, and it's better to hear that from us on day one than discover it mid-job.
You're right on the C&O Canal and the Potomac here, and if you're on one of the low-lying blocks near the waterfront, flash-flood intrusion during major storms is a documented risk, not a hypothetical one. If your property has taken on water during a storm, don't assume it dried out fine on its own — that's exactly the kind of thing worth having verified.
