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

Halo Water Proofing is a licensed and insured Exterior Waterproofing company built around one idea: show up when you say you will, explain the problem in plain language, and fix it so it stays fixed.

Every technician on our Greenwich 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 Greenwich 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.
Even small cracks are worth a second look — they rarely stay small once seasonal ground movement gets involved.
It's easy to dismiss efflorescence as harmless dust, but it actually signals active moisture movement through the wall.
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 Greenwich customers not to wait on — wall movement tends to progress rather than resolve on its own.
Flooring that's cupping or warping near an exterior wall is a common clue our Greenwich crews trace back to a drainage issue.
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.
When your Greenwich basement floods, minutes matter for your drywall, flooring, and belongings. We dispatch a crew around the clock, pull the water, and start drying the space with commercial-grade equipment the same visit.
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 →A damp, uninsulated crawl space under a Greenwich home drives up humidity, invites mold, and wastes energy year-round. We seal it with heavy-duty vapor barrier, address any standing moisture, and can add dehumidification if needed.
Get a Crawl Space Quote →We work directly with Greenwich property managers and business owners on below-grade waterproofing, parking structure sealing, and large-scale drainage corrections — scheduled around your operating hours.
Request a Commercial Quote →No confusing steps, no hard sell — just the same process our Greenwich crews follow on every job.
You call +1-866-476-1348 and talk to a real technician who asks the right questions to understand what's likely happening at your Greenwich property.
A technician inspects the Greenwich property in person, checking the foundation, drainage, grading, and any active moisture before recommending a fix.
You receive a written, itemized quote before any work begins — the number you approve is the number you're billed.
Once the repair is done, you get documentation of the work and a written warranty — not just a handshake.
There's no verbal quote that magically grows once the crew arrives at your Greenwich property — the written estimate is the final word.
Our trucks stage locally around Greenwich, which is why emergency calls typically get a technician on-site in under two hours, not "sometime tomorrow."
Our repairs come with written, transferable warranties — a real asset if you sell the Greenwich property later.
We'd rather earn a repeat customer with an honest small fix than push a system you don't need.
We can supply the photo documentation and repair scope most Greenwich, NJ carriers ask for before approving a claim.
Every Greenwich job reflects on the next referral, so we treat each one like it's the only advertising that matters.
"They came out the same afternoon I called about water coming in during a storm. Explained everything before they touched anything. Basement's been bone dry since."
"Fair price, showed up on time, cleaned up after themselves. Wish more contractors worked like this."
"Crawl space smelled awful for years. Encapsulation crew did a clean job and the smell is completely gone upstairs now."
"Managed our building's parking garage waterproofing project. Kept to the schedule, communicated well with tenants, minimal disruption."
"French drain install took two days like they said it would, not five. Yard was put back together better than before."
"Technician actually explained why the water was coming in instead of just quoting a number. First contractor who's done that for us."
Whether you're in the older, established parts of Greenwich or a newer subdivision still settling, our crews have likely already worked on a foundation like yours nearby.
