A lot of Potomac, MD exterior waterproofing failures trace back to a footing drain that was installed without proper slope, which means it never actually moved water the way it was supposed to. We verify slope during installation, not just at design.
Exterior work involves excavation near the foundation, and every crew member is trained and insured for that specific scope.
Excavation equipment and membrane materials are staged locally so an exterior project doesn't wait on out-of-town logistics.
Landscaping restoration is included in the scope, not billed as a separate surprise line item.
We install dimpled membrane rated for below-grade use, paired with a footing drain that ties into your existing or new drainage system.
Every Potomac, MD Exterior Waterproofing job starts with an inspection, not a generic package — here's what that typically includes.
This is the most comprehensive Potomac, MD waterproofing fix available, addressing the wall itself rather than just managing water after it gets in.
We slope footing drains correctly during installation, since a flat or reverse-sloped drain simply won't move water.
Soil that slopes toward the foundation instead of away from it is one of the most common Potomac, MD water intrusion causes, and it's often the cheapest fix on this list.
We also inspect and reseal the window frame itself while the well is open.
This is often bundled with grading correction since the two issues usually show up together.
Photos of the exterior foundation area help us plan equipment and access before the visit.
We flag any utility lines or landscaping features that need special handling during excavation.
We explain what's included in landscaping restoration so there's no confusion after backfill.

Interior systems manage water after it enters; exterior systems stop water from reaching the wall in the first place, which is more invasive but often more permanent.
Some disruption is unavoidable near the foundation, but we restore grading and replant where reasonable as part of the scope.

We'll walk through both options and their trade-offs so you can make an informed choice.
