Exterior membrane systems, footing drains, and corrected grading tackle Greenbelt, MD water intrusion at the source, before it ever reaches the interior wall.
Exterior work only pays off if the membrane, footing drain, and grading are all addressed together — fixing one without the others often leaves the underlying pressure problem unresolved. We scope the full picture before recommending excavation.
We call in utility locates before any digging starts, standard on every Greenbelt, MD exterior job.
Weather-dependent scheduling means we plan exterior jobs around Greenbelt, 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.
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.
We slope footing drains correctly during installation, since a flat or reverse-sloped drain simply won't move water.
We regrade the perimeter to direct surface water away from the wall, typically paired with downspout extensions.
Window wells collecting water get excavated, fitted with a gravel bed, and tied into the exterior drain system so they stop acting as a funnel toward the foundation.
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.
A technician walks the exterior perimeter, checks grading slope, and identifies where excavation would be needed for a membrane or footing drain fix.
You'll see linear footage, membrane type, and footing drain scope broken out with pricing before any digging starts.
We restore grading and any disturbed landscaping as the final step before calling the job complete.

Excavation typically goes down to the footing, which varies by home but is often four to eight feet depending on foundation depth.
We'll walk through both options and their trade-offs so you can make an informed choice.
Yes — grading correction and downspout extension are often standalone fixes that resolve a surprising number of Greenbelt, MD water intrusion issues on their own.
