Halo Water Proofing is a NJ-licensed Exterior Waterproofing company that treats every Greenwich job like it's the only one on the schedule.
We don't run a bidding war between crews. The Greenwich technician who inspects your property is the same one who does the repair, start to finish.

One phone call gets you a straight answer and a real appointment — not a vague callback promise.
📞 +1-866-476-1348Catching one of these early usually means a smaller repair bill and a lot less stress for Greenwich homeowners.
A musty smell usually means moisture is already moving through your Greenwich basement, even if the floor looks bone dry.
A crack that wasn't there last year is worth a look before it becomes an active leak point.
It's easy to mistake efflorescence for harmless dust, but it actually signals active moisture movement.
If your pump only shuts off for a few minutes at a time, it's worth having it checked before it fails outright.
If a foundation wall looks like it's curving inward, that's beyond a simple patch and needs a real assessment.
Flooring that's cupping near an exterior wall often traces straight back to a basement moisture issue below.
From a 2 a.m. sump pump failure to a planned exterior drainage project, here's what our Greenwich crews handle most.
A flooded Greenwich basement doesn't wait for morning, and neither do we. Our crews pull the standing water and start drying the space the same visit.
Get Emergency Help →Not every crack means a structural problem, but every crack deserves a real look. We'll tell you which kind yours is.
Ask About Crack Repair →A failed sump pump is the top reason for emergency calls across Greenwich after heavy rain — we install pumps sized to your actual water volume, plus battery backup for power outages.
Book a Pump Check →Some Greenwich properties need both systems working together — we'll say so honestly instead of selling just one.
Talk Drainage Options →Older Greenwich homes with vented crawl spaces see the biggest swings in seasonal humidity — encapsulation closes that off for good.
Get a Crawl Space Quote →We handle below-grade waterproofing for Greenwich property managers and business owners, scheduled around your operating hours to limit disruption.
Request a Commercial Quote →Here's exactly what Greenwich customers can expect from first call to final walkthrough.
A real technician asks the right questions to understand what's likely happening at your Greenwich property before anyone drives out.
A Greenwich technician walks the property, checks the foundation and drainage, and explains what's found in plain language.
No verbal number that quietly grows once the truck pulls up — the written quote is the final word.
Our crew completes the repair, cleans up, and walks you through the warranty on what was installed.
Plenty of companies advertise Exterior Waterproofing in Greenwich — here's what actually separates the ones worth calling from the ones that aren't.
You get a real number before any work starts — what you approve is what you're billed.
A local dispatch model means the technician who answers your questions is the same one who shows up.
If a covered repair fails, we come back and fix it. That's part of the contract, not just a promise.
Our technicians are trained to diagnose accurately, not to upsell — that changes the advice you actually get.
We can supply the documentation most carriers ask for before approving a Greenwich claim.
Every Greenwich job reflects on the next referral, so we treat each one like it matters.
"Woke up to a wet basement and had someone out by mid-morning. No pressure, no upsell, just fixed it."
"Got three quotes for a crack repair. This was the only company that actually explained why the crack was happening instead of just naming a price."
"Our sump pump died during the worst storm of the year, obviously. Battery backup was installed the next day and we haven't worried since."
"Handled waterproofing for our parking structure with minimal disruption to tenants and stuck to the schedule."
"French drain install took two days exactly as quoted, and the yard looked better than before."
"First contractor who actually explained where the water was coming from instead of just quoting a number."
"Crew was respectful of our landscaping during the drain install and left the yard looking better than before they started."
We back our Greenwich work with real, transferable warranties because we plan to be here long after the job is done, not just for the one visit.
