A lot of Hewlett, NY 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.
Membrane seams are overlapped and sealed to manufacturer spec so the barrier performs as designed for decades, not just years.
Every Hewlett, NY Exterior Waterproofing job starts with an inspection, not a generic package — here's what that typically includes.
This is the most comprehensive Hewlett, NY waterproofing fix available, addressing the wall itself rather than just managing water after it gets in.
A perforated footing drain collects groundwater at the base of the foundation and routes it away before it can build pressure against the wall.
Soil that slopes toward the foundation instead of away from it is one of the most common Hewlett, NY water intrusion causes, and it's often the cheapest fix on this list.
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.
Photos of the exterior foundation area help us plan equipment and access before the visit.
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.
"Interior fixes hadn't worked for us — turned out the real problem was grading pushing water straight at the foundation. Exterior correction solved it."
— Hewlett Homeowner
"They found our downspouts were dumping water two feet from the foundation. Extended them and regraded, and that alone made a noticeable difference."
— Hewlett Customer
"Appreciated that they called in utility locates before digging near our gas line."
— Hewlett Homeowner
"Fast turnaround given how much digging was involved."
— Hewlett 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.
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 Hewlett, NY water intrusion issues on their own.
