When water is reaching your foundation from the outside — through poor grading, a failed membrane, or saturated soil — the fix belongs outside too, not just inside masking the symptom.

What "specialized" actually means for exterior waterproofing at our company — not a marketing word, a set of specific practices.
Certification covers grading assessment, drainage board installation, and rubberized membrane application to manufacturer spec.
Active water intrusion visible from outside — pooling against the foundation, saturated soil — moves to priority scheduling.
Quotes break out excavation linear footage, membrane material, footing drain installation, and backfill/regrading separately, in writing.
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.
Drainage board goes over the membrane to create a channel for water to travel 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 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.
Soil that slopes toward the foundation instead of away from it sends every rainfall straight at your basement wall, regardless of how good the membrane below is.
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.
