Interior drain tile, sump basins, and vapor barrier wall systems installed by technicians who've done this hundreds of times in Potomac, MD basements.
We've seen enough Potomac, MD basements to know that a wet spot in one corner rarely tells the whole story. Before we recommend drain tile or a sump upgrade, we trace the water back to where it's actually entering, not just where you noticed it.
Every technician carries full state licensing and liability coverage before they ever step into your basement.
Most inspection requests get a same-day or next-day appointment, not a two-week wait.
No hourly billing and no change orders once your basement floor is already open.
We use pin-type moisture meters and a flashlight-and-crowbar inspection to trace water back to its real entry point.
Every Potomac, MD Basement Waterproofing job starts with an inspection, not a generic package — here's what that typically includes.
We route drain tile beneath the existing slab line so flooring disruption stays minimal during installation.
Battery backup is available for any sump system, so a power outage during a storm doesn't undo the whole fix.
Vertical wall cracks get epoxy or polyurethane injection depending on whether they're still actively weeping.
A dimpled plastic membrane behind any finished basement wall channels residual moisture down to the drain tile instead of trapping it behind drywall.
Poor window well drainage is one of the most overlooked Potomac, MD basement leak sources, and it's often the cheapest fix on the list.
