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.

Four commitments that separate a properly trained exterior waterproofing crew from a generalist showing up with a truck and a hope.
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.
Footing drains are set in washed gravel and wrapped in filter fabric to resist silt clogging over the system's service life.
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.
Photos of the affected exterior area, texted ahead of the visit, help the technician plan equipment needs before arriving.
You'll get a text confirmation with an arrival window and any documents needed, like utility locate authorization.
Utility locates are scheduled ahead of excavation as standard practice, not an afterthought.
Excavation sites are backfilled, compacted, and regraded to proper slope before the crew leaves, with landscaping restoration included where disturbed.
