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.
Call +1-866-476-1348
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.
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.
Drainage board over the membrane channels water to the footing drain rather than letting pressure build against the wall.
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.
A footing drain intercepts groundwater at the base of the foundation and carries it away before it can build pressure against the wall.
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.
Describe what you're seeing from outside — pooling water, visible staining on the wall, saturated soil — and dispatch routes a crew equipped for exterior assessment.
Technicians walk the full property perimeter before recommending excavation, checking grading and downspout placement.
Pricing is itemized by excavation footage and membrane material, in writing before any digging begins.
Membrane and footing drain work carries a written warranty against failure at the treated wall section.
