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 is a licensed and insured 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.
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.
It's easy to dismiss efflorescence as harmless dust, but it actually signals active moisture movement through the wall.
A pump under constant strain tends to fail at the worst possible time — usually during the next big Greenwich storm.
A bowing basement wall is a structural concern in addition to a water one — this is the kind of Greenwich call we prioritize fast.
Peeling paint low on a basement wall or warped baseboards upstairs often trace back to moisture migrating up from below.
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 pump out the basement 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 →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 →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 →We can phase larger Greenwich commercial projects around business hours or tenant schedules so operations aren't disrupted mid-project.
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.
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.
A local dispatch model means the technician who answers questions about your Greenwich job is the same one who shows up to do it.
Warranty terms are explained before you sign, in plain language, so there's no fine print surprise if you ever need to use it.
We'd rather earn a repeat customer with an honest small fix than push a system you don't need.
We document the damage with photos and a written scope your insurance adjuster can actually use, and we'll walk you through the claim process.
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."
"Straightforward commercial quote, no back-and-forth, crew was professional the whole project."
"We had three foundation cracks and expected a huge bill. Turned out only one needed injection — they didn't try to sell us on the other two. That honesty is rare."
"Technician actually explained why the water was coming in instead of just quoting a number. First contractor who's done that for us."
