When water reaches your foundation from the outside, through poor grading, a failed membrane, or saturated soil, the fix belongs outside too, not just masked from the inside.

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 distinct discipline requiring different technique and specialized equipment.
Initial exterior assessments, requiring a full perimeter walk, are typically scheduled within a few days across our service area.
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.
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.
We regrade the perimeter to direct water away from the structure and coordinate downspout extensions as part of a complete fix.
We install well drains tied into the footing drain system with a clear cover to reduce debris.
Sealing from the exterior addresses hydrostatic pressure at the point of entry rather than relying solely on interior injection.
Here's what happens between your call and a completed exterior fix.
Photos of the affected area, texted ahead, help the technician plan equipment before arriving.
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 excavation, drain repair, or grading correction alone.
Membrane and footing drain work carries a written warranty against failure at the treated wall section.
Real feedback from Riverside-area customers who called us for exterior waterproofing.
"They found our footing drain had completely collapsed after thirty years — explains why interior fixes never fully worked before."
"Regraded the whole side yard and extended our downspouts as part of the job. Haven't seen water against that wall since."
"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."
The questions Riverside customers ask us before booking exterior waterproofing service.
Our exterior waterproofing crews cover Riverside and the surrounding Riverside, NY service area, with regional dispatch keeping response times tight regardless of which part of the footprint you're in.
Because exterior work requires excavation crews, coverage is more regional than interior services — worth confirming by phone either way.
