Halo Water Proofing has been the Leonia area's go-to call for Interior Drainage System because we answer the phone, show up on time, and stand behind the work.

Halo Water Proofing started as a small NJ crew and grew because Leonia customers kept referring us to neighbors — that's still how most of our work comes in today.

Every technician on our Leonia crew is background-checked, factory-trained on the equipment we install, and held to the same estimate we quote you over the phone — no upsell surprises when the truck pulls up.
Call now and talk to an actual technician, not a script. We'll walk you through what's likely going on and get a crew scheduled.
📞 +1-866-476-1348Most Leonia customers didn't wake up one day with a flooded basement. It usually started small. These are the early signs worth calling about.
If the basement smells damp even when it looks dry, moisture is likely moving through the walls or floor somewhere.
Hairline cracks can widen over a Leonia winter's freeze-thaw cycle and become active leak points by spring.
That white chalky film on basement walls is efflorescence — mineral deposits left behind as water evaporates through concrete.
If your pump is running around the clock instead of only during storms, it's worth having it evaluated before it fails completely.
This is one sign we tell Leonia customers not to wait on — wall movement tends to progress rather than resolve on its own.
These signs upstairs are often the last clue Leonia homeowners notice, even though the moisture issue started in the basement months earlier.
Every Leonia property is different — soil, slope, foundation age, water table depth. We size the fix to the actual problem, not a one-size package.
Storm season in Leonia, NJ means our emergency line gets busy fast — we triage calls by severity so active flooding at your Leonia address jumps the queue ahead of routine inspections.
Call for Emergency Service →Freeze-thaw cycles in Leonia, NJ push existing cracks wider every winter, which is why we recommend sealing them before they become an active leak rather than after.
Get a Crack Assessment →A tired or undersized sump pump is the #1 reason we get emergency calls in Leonia after heavy rain. We install battery backup units so your basement stays dry even if the power goes out mid-storm.
