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

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.
Initial exterior assessments, which require walking the full property perimeter, are typically scheduled within a few days.
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.
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.
We regrade the perimeter to direct water away from the structure and coordinate downspout extensions as part of a complete exterior fix.
We install window well drains tied into the footing drain system, plus a clear cover to reduce debris accumulation.
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.
Active pooling against the foundation is flagged for priority scheduling.
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 Blaine-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."
