When water is reaching your foundation from the outside — through poor grading, a failed membrane, or saturated soil — the fix belongs outside too, not just inside masking the symptom.

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.
Local crews understand your region's soil composition and typical frost depth, both of which affect excavation planning.
Pricing accounts for landscaping restoration where excavation disturbs existing beds or hardscape.
We apply rubberized asphalt or sheet membrane systems rated for below-grade application, not a consumer-grade coating that degrades within a few seasons.
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.
We install window well drains tied into the footing drain system, plus a clear cover to reduce debris accumulation.
Sealing from the exterior addresses hydrostatic pressure at the point of entry rather than relying solely on an interior injection to manage it after the fact.
Here's what happens between your call and a completed exterior fix.
Describe what you're seeing from outside — pooling water, visible efflorescence on the wall, soil that stays saturated — and dispatch routes a crew equipped for an exterior assessment.
Technicians walk the full property perimeter before recommending excavation, checking grading, downspout placement, and existing drainage.
Utility locates are scheduled ahead of excavation as standard practice, not an afterthought.
We document the completed system with photos before backfilling, so you have a record of exactly what's below grade.
Real feedback from Northfield-area customers who called us for exterior waterproofing.
"They found our footing drain had completely collapsed after thirty years — explains why the interior fixes never fully worked before."
"Regraded the whole side yard and extended our downspouts as part of the job. Haven't seen water against that wall since."
"Excavation crew was careful with our landscaping and put everything back better than it was before."
"Appreciated that they explained why interior injection alone wasn't going to solve our specific problem before recommending exterior work."
