Exterior membrane systems, footing drains, and corrected grading tackle Malverne, NY 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.
Weather-dependent scheduling means we plan exterior jobs around Malverne, NY'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 Malverne, NY 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.
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.
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.
We explain what's included in landscaping restoration so there's no confusion after backfill.
We restore grading and any disturbed landscaping as the final step before calling the job complete.
"Membrane and footing drain install took three days but the wall that used to weep every storm has been bone dry since."
— Malverne Homeowner
"They found our downspouts were dumping water two feet from the foundation. Extended them and regraded, and that alone made a noticeable difference."
— Malverne Customer
"Window well kept flooding every storm. They excavated, added drainage, and resealed the window frame while they were at it."
— Malverne Homeowner
"Footing drain from the original builder had failed completely. New one actually slopes correctly and moves water like it should."
— Malverne Customer
We'll recommend the right approach based on what the inspection actually finds.
We discuss landscaping impact during the estimate so there are no surprises.
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.
We'll recommend starting there if the inspection suggests surface water is the primary cause.
A typical residential wall section with membrane and footing drain work takes a few days depending on access and weather conditions.
