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.

What "specialized" actually means for exterior waterproofing at our company — not a marketing word, a set of specific practices.
Certification covers grading assessment and rubberized membrane application to manufacturer spec, verified on every job.
Initial exterior assessments, requiring a full perimeter walk, are typically scheduled within a few days across our service area.
Quotes break out excavation footage, membrane material, footing drain installation, and backfill separately in writing.
We apply rubberized asphalt or sheet membrane rated for permanent below-grade exposure, not a consumer coating that degrades in a season or two.
Each service below is scoped specifically to exterior waterproofing, not a generic waterproofing menu with the name swapped in.
We excavate along the affected wall section down to the footing, prep the surface, and apply a rubberized membrane rated for permanent below-grade exposure. 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.
Soil sloping toward the foundation 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 wall — often the source of a leak that seemed to come from nowhere.
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.
Active pooling against the foundation is flagged for priority scheduling.
You'll get a text confirmation with an arrival window and any documents needed, like utility locate authorization.
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.

"Excavation crew was careful with our landscaping and put everything back better than it was before."
"They explained why interior injection alone wasn't going to solve our specific problem before recommending exterior work."
