We're Halo Water Proofing — a NJ-licensed, fully insured waterproofing outfit that's spent years learning exactly how water moves through Greenwich-area foundations, and exactly how to stop it.

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.
Stair-step cracks in block foundations are a common early warning sign we see across Greenwich-area homes.
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.
If a foundation wall looks like it's leaning or bulging inward, that's beyond a simple seal and needs a full assessment.
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.
Standing water in your basement doesn't wait for business hours, and neither do we. Our Greenwich emergency crews extract standing water first, then diagnose the entry point so it doesn't happen again next storm.
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 →Already have a sump pump that's failing or too small for your Greenwich lot? We'll test it, tell you honestly whether it needs replacing, and size the new one to your actual water volume — not the cheapest unit on the truck.
Schedule a Pump Inspection →Some Greenwich lots need both an interior and exterior system working together — we'll tell you honestly if that's the case rather than selling just one.
Ask About Drain Systems →Musty smell upstairs that you can't explain? It's usually the crawl space. Our Greenwich crews encapsulate the space fully — floor, walls, and vents — so moisture stops migrating into your living areas.
Get a Crawl Space Quote →Commercial properties in Greenwich carry bigger stakes when water gets in: inventory, tenants, downtime. We scope commercial jobs with the same crew leads who run our residential work, backed by written specs and timelines.

We start with a phone conversation, not a script — enough to know whether this is an emergency dispatch or a scheduled inspection.
We walk the space with you, point out what we find, and explain it in plain language — no jargon, no pressure.
You receive a written, itemized quote before any work begins — the number you approve is the number you're billed.
Our crew completes the work, cleans up the site, and walks you through the warranty coverage on what was installed.
There's no verbal quote that magically grows once the crew arrives at your Greenwich property — the written estimate is the final word.
Because we're actually based near Greenwich rather than routing calls through a national center, we can usually get someone out the same day you call.
If a covered repair fails, we come back and make it right. That's written into every contract, not just promised on the phone.
If your Greenwich basement just needs a $200 crack seal instead of a $12,000 system, that's what we'll tell you.
