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.

What "specialized" actually means for exterior waterproofing at our company — not a marketing word, a set of specific practices.
Certification covers grading assessment, drainage board installation, and rubberized membrane application to manufacturer spec.
Active water intrusion visible from outside — pooling against the foundation, saturated soil — moves to priority scheduling.
No surprise charges for unexpected utility lines or rock encountered during excavation — those are flagged and discussed before proceeding.
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.
Older homes often have footing drains that have silted in or collapsed over decades — we assess existing drain condition and replace where compromised.
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.
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.
Most Londonderry, OH 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.
Excavation sites are backfilled, compacted, and regraded to proper slope before the crew leaves, with landscaping restoration included where disturbed.
What Londonderry, OH 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."
"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."
