Exterior membrane systems, footing drains, and corrected grading tackle Mullica Hill, NJ 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.
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.
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.
Downspouts discharging within a few feet of the foundation send roof water directly toward the problem — we extend them well clear of the wall.
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.
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 fixes hadn't worked for us — turned out the real problem was grading pushing water straight at the foundation. Exterior correction solved it."
— Mullica Hill Homeowner
"They found our downspouts were dumping water two feet from the foundation. Extended them and regraded, and that alone made a noticeable difference."
— Mullica Hill Customer
"Window well kept flooding every storm. They excavated, added drainage, and resealed the window frame while they were at it."
— Mullica Hill Homeowner
"Footing drain from the original builder had failed completely. New one actually slopes correctly and moves water like it should."
— Mullica Hill Customer
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 measure your specific foundation during the on-site inspection rather than assuming a standard 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 Mullica Hill, NJ water intrusion issues on their own.
Larger projects or difficult access points can extend the timeline, which we'll outline in the written quote.
