From a hairline foundation crack to a fully flooded crawl space, Halo Water Proofing has handled it in Greenwich before. We show up, we diagnose it straight, and we fix it right.

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

We don't send apprentices to figure it out on your dime. Every Greenwich job is run by a technician who has done this exact repair dozens of times, with a supervisor who signs off before we call it finished.
One call gets you a straight answer and a real appointment window — not a call-back promise.
📞 +1-866-476-1348Water problems rarely announce themselves all at once — they usually show up as small clues first. Here's what our Greenwich technicians hear about most often before an inspection.
A musty smell in the basement or crawl space is usually moisture you can't see yet, not just "old house smell."
Even small cracks are worth a second look — they rarely stay small once seasonal ground movement gets involved.
That white chalky film on basement walls is efflorescence — mineral deposits left behind as water evaporates through concrete.
A pump under constant strain tends to fail at the worst possible time — usually during the next big Greenwich storm.
This is one sign we tell Greenwich customers not to wait on — wall movement tends to progress rather than resolve on its own.
These signs upstairs are often the last clue Greenwich homeowners notice, even though the moisture issue started in the basement months earlier.
Every Greenwich 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 Greenwich, NJ means our emergency line gets busy fast — we triage calls by severity so active flooding at your Greenwich address jumps the queue ahead of routine inspections.
Call for Emergency Service →A cracked foundation wall isn't just a cosmetic issue — it's a water entry point and, over time, a structural one. Our Greenwich crews assess whether it's a simple seal or a sign of bigger settlement issues before recommending a fix.
Get a Crack Assessment →Most sump pump failures we see in Greenwich happen during the exact storms that need them most — a battery backup closes that gap when the power drops.
Schedule a Pump Inspection →For Greenwich properties fighting grading or drainage issues, an exterior French drain can intercept water before it ever reaches the foundation wall at all. We map your yard's slope and water flow before recommending which approach fits.
Ask About Drain Systems →Older Greenwich homes with vented crawl spaces are especially prone to seasonal moisture swings — encapsulation closes that off for good.
