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

What "specialized" actually means for exterior waterproofing at our company — not a marketing word, a set of specific practices.
We don't treat exterior work as a bigger version of interior injection — it's a different discipline requiring different equipment and technique.
Active water intrusion visible from outside — pooling against the foundation, saturated soil — moves to priority scheduling.
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.
We don't run a one-size-fits-all playbook — every exterior waterproofing job starts from these core service components, adapted to what your property actually needs.
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.
We regrade the perimeter to direct water away from the structure and coordinate downspout extensions as part of a complete exterior fix.
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.
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.
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 Skillman, NJ exterior assessments are scheduled within a few days given the scope of a proper perimeter evaluation.
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 Skillman-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."
The questions Skillman customers ask us before booking exterior waterproofing service.
Our exterior waterproofing crews cover Skillman and the surrounding Skillman, NJ service area, with regional dispatch keeping response times tight regardless of which part of the footprint you're in.
Because exterior work requires excavation crews, coverage is more regional than interior services — worth confirming by phone either way.
