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.
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.
No surprise charges for unexpected utility lines or rock encountered during excavation — those are flagged and discussed before proceeding.
We apply rubberized asphalt or sheet membrane systems rated for below-grade application, not a consumer-grade coating that degrades within a few seasons.
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, 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.
You'll get a text confirmation with an arrival window and any documents needed, like utility locate authorization.
A full grading and drainage evaluation identifies whether the fix needs full excavation, footing drain repair, or grading correction alone.
We document the completed system with photos before backfilling, so you have a record of exactly what's below grade.
