Exterior Waterproofing in Severna Park, MD — Stop Water Before It Reaches the Wall
We excavate only where necessary and restore landscaping as part of the scope.
We excavate only where necessary and restore landscaping as part of the scope.
A lot of Severna Park, 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.
We scope every Exterior Waterproofing job in person before quoting it, since two properties with the same symptom rarely need the same fix.
We excavate to the footing, apply a dimpled waterproof membrane directly to the foundation wall, and backfill with proper drainage material.
A perforated footing drain collects groundwater at the base of the foundation and routes it away before it can build pressure against the wall.
We regrade the perimeter to direct surface water away from the wall, typically paired with downspout extensions.
We also inspect and reseal the window frame itself while the well is open.
Downspouts discharging within a few feet of the foundation send roof water directly toward the problem — we extend them well clear of the wall.
We ask about grading, downspout placement, and where interior water is showing up to narrow down the likely exterior cause.
We flag any utility lines or landscaping features that need special handling during excavation.
You'll see linear footage, membrane type, and footing drain scope broken out with pricing before any digging starts.
Excavation, membrane installation, and backfill for a typical residential wall section usually take a few days depending on access and weather.

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.
