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

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 excavation depth, membrane application, and footing drain installation specific to exterior systems.
Initial exterior assessments, requiring a full perimeter walk, are typically scheduled within a few days across our service area.
No surprise charges for unexpected utility lines or rock encountered during excavation — those are flagged and discussed first.
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.
Drainage board over the membrane channels water 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.
Older homes often have drains that have silted in or collapsed over decades — we assess and replace where compromised.
We regrade the perimeter to direct water away from the structure and coordinate downspout extensions as part of a complete fix.
Window wells without proper drainage collect and hold water against a vulnerable point in the 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 interior injection.
Four steps, start to finish — from your call to a backfilled, regraded foundation wall.
Photos of the affected area, texted ahead, help the technician plan equipment before arriving.
Technicians walk the full property perimeter before recommending excavation, checking grading and downspout placement.
Utility locates are scheduled ahead of excavation as standard practice.
Excavation sites are backfilled, compacted, and regraded to proper slope before the crew leaves, with landscaping restoration included.
