Foundation leaking? Basement smells off? Halo Water Proofing sends a real technician to your Greenwich property, gives you a straight answer, and fixes it right the first time.
Free, no-obligation estimates · 24/7 dispatch
We built Halo Water Proofing around a simple promise: show up when we say, tell you the truth about what's wrong, and fix it so it stays fixed.
Every Greenwich technician we send is background-checked and trained on the exact equipment we install — not a subcontractor picked up for the day.
We've worked on foundations from decades-old Greenwich homes to brand-new builds still settling into their soil, so whatever your basement is dealing with, we've likely seen a version of it nearby.
One phone call gets you a straight answer and a real appointment — not a vague callback promise.
📞 +1-866-476-1348Water problems build slowly before they become emergencies. These are the clues our Greenwich crews hear about most.
If the basement smells damp no matter the season, water is likely finding a way in somewhere you can't see.
Small cracks in a Greenwich foundation rarely stay small — seasonal ground movement tends to widen them over time.
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.
These upstairs clues usually show up months after the basement moisture problem actually started.
From a 2 a.m. sump pump failure to a planned exterior drainage project, here's what our Greenwich crews handle most.
When water shows up fast, we move fast — extraction, drying equipment, and a plan to stop it from happening again.
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 →Musty smell upstairs with no obvious source? Check the crawl space first — it's usually the culprit.
Get a Crawl Space Quote →We can phase larger Greenwich commercial projects around business hours or tenant schedules so operations keep running.
Request a Commercial Quote →No pressure, no scripts — just what actually happens once you call +1-866-476-1348.

Word of mouth is still how most Greenwich customers find us, which keeps our standards high.
"Woke up to a wet basement and had someone out by mid-morning. No pressure, no upsell, just fixed it."
"Fair price, on time, cleaned up after. Wish every contractor worked this way."
"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."
"Sump pump inspection was thorough and they didn't try to sell me a new one when mine just needed a part replaced."
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.
