Exterior waterproofing addresses the source directly: excavation, membrane application, and footing drainage designed to keep water away from the wall in the first place.

Four commitments that separate a properly trained exterior waterproofing crew from a generalist showing up with a truck and a hope.
Crews are trained in proper excavation depth, membrane application technique, and footing drain installation specific to exterior waterproofing systems.
Initial exterior assessments, which require walking the full property perimeter, are typically scheduled within a few days.
Pricing accounts for landscaping restoration where excavation disturbs existing beds or hardscape.
Drainage board installed over the membrane channels water down to the footing drain rather than letting hydrostatic pressure build against the wall.
Each service below is scoped specifically to exterior waterproofing, not a generic waterproofing menu with the name swapped in.
We excavate along the affected wall section down to the footing, clean and prep the existing foundation surface, and apply a rubberized waterproofing membrane rated for permanent below-grade exposure. This is the most thorough exterior fix available and typically carries the longest service life of any waterproofing method.
A footing drain intercepts groundwater at the base of the foundation and carries it away via gravity or a connected sump system before it can build pressure against the wall.
Soil that slopes toward the foundation instead of away from it sends every rainfall straight at your basement wall, regardless of how good the membrane below is.
Window wells without proper drainage collect and hold water against a vulnerable point in the foundation wall — often the source of a leak that seemed to come from nowhere.
Cracks and cold joints exposed during excavation get treated directly at the source, from the outside, before the membrane goes over them.
Four steps, start to finish — from your call to a backfilled, regraded foundation wall.
Active pooling against the foundation is flagged for priority scheduling.
Most Newfane, NY exterior assessments are scheduled within a few days given the scope of a proper perimeter evaluation.
A full grading and drainage evaluation identifies whether the fix needs full excavation, footing drain repair, or grading correction alone.
Excavation sites are backfilled, compacted, and regraded to proper slope before the crew leaves, with landscaping restoration included where disturbed.
What Newfane, NY customers are saying after their exterior waterproofing service.
"They found our footing drain had completely collapsed after thirty years — explains why the interior fixes never fully worked before."
