Exterior membrane systems, footing drains, and corrected grading tackle Dunkirk, MD water intrusion at the source, before it ever reaches the interior wall.
A lot of Dunkirk, 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.
Weather-dependent scheduling means we plan exterior jobs around Dunkirk, MD's rainy season windows when possible.
Pricing is quoted per linear foot of foundation wall being treated, based on an on-site measurement, not a phone estimate.
Membrane seams are overlapped and sealed to manufacturer spec so the barrier performs as designed for decades, not just years.
Every Dunkirk, MD Exterior Waterproofing job starts with an inspection, not a generic package — here's what that typically includes.
We excavate to the footing, apply a dimpled waterproof membrane directly to the foundation wall, and backfill with proper drainage material.
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 Dunkirk, 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.
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.

"Window well kept flooding every storm. They excavated, added drainage, and resealed the window frame while they were at it."
— Dunkirk Homeowner
"Footing drain from the original builder had failed completely. New one actually slopes correctly and moves water like it should."
— Dunkirk Customer
We'll recommend the right approach based on what the inspection actually finds.
Some disruption is unavoidable near the foundation, but we restore grading and replant where reasonable as part of the scope.
We measure your specific foundation during the on-site inspection rather than assuming a standard depth.
Generally yes, since it involves excavation, but it addresses the source of water intrusion rather than managing symptoms after entry.
