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.
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.
Quotes break out excavation linear footage, membrane material, footing drain installation, and backfill/regrading separately, in writing.
Footing drains are set in washed gravel and wrapped in filter fabric to resist silt clogging over the system's service life.
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.
Drainage board goes over the membrane to create a channel for water to travel down to the footing drain instead of pressing against the wall. 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.
Cracks and cold joints exposed during excavation get treated directly at the source, from the outside, before the membrane goes over them.
Here's what happens between your call and a completed exterior fix.
Photos of the affected exterior area, texted ahead of the visit, help the technician plan equipment needs before arriving.
Most Newport, SC 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 Newport, SC 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."
