When water reaches your foundation from the outside, through poor grading, a failed membrane, or saturated soil, the fix belongs outside too, not just masked from the inside.

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 distinct discipline requiring different technique and specialized equipment.
Active pooling against the foundation moves to priority scheduling ahead of routine appointments.
Pricing accounts for landscaping restoration where excavation disturbs existing beds or hardscape.
We apply rubberized asphalt or sheet membrane rated for permanent below-grade exposure, not a consumer coating that degrades in a season or two.
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, prep the surface, and apply a rubberized membrane rated for permanent below-grade exposure. This is the most thorough exterior fix available and typically carries the longest service life.
Older homes often have drains that have silted in or collapsed over decades — we assess and replace where compromised.
Soil sloping toward the foundation sends every rainfall straight at your basement wall, regardless of how good the membrane below is.
We install well drains tied into the footing drain system with a clear cover to reduce debris.
Cracks and cold joints exposed during excavation get treated directly from the outside before the membrane goes over them.
Here's what happens between your call and a completed exterior fix.
Active pooling against the foundation is flagged for priority scheduling.
You'll get a text confirmation with an arrival window and any documents needed, like utility locate authorization.
A full grading and drainage evaluation identifies whether the fix needs excavation, drain repair, or grading correction alone.
Membrane and footing drain work carries a written warranty against failure at the treated wall section.
What Dupont, PA customers are saying after their exterior waterproofing service.
"They found our footing drain had completely collapsed after thirty years — explains why 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."
"They explained why interior injection alone wasn't going to solve our specific problem before recommending exterior work."
